MEASURING WITH HP 54600 SCOPE

Hello
I am new user of labview and I am trying to make a program that measures the output of a simple circuit (ie LP filter) and shows it on the labview display window in time domain and to modify it to show the magnitude as a function of frequency.I managed to have the right sinusoidal curve on the oscilloscope (hp54600B) display but I only get a ramp on my labview window
I am using version 7.1 and using a GPIB and the hp 33120A waveform generator
i appreciate if any one can take a look at the program code and advice how to change it.
Thanks in advance

Don't have to shout.
Did you also download the driver for the 33120A? I would recomend you do that as well. One of the functions is ag33xxx - config Waveform. This has a frequency input control. You can put the function gen and scope VIs inside a loop and increment the frequency with each iteration of the loop. There are several ways to do that. You can create an array of values and with each iteration, you index the next frequency value out of the array. You can also do it with a calculation. You can provide a start value, an increment, and a final value. You would wire your start value to a shift register and with each iteration, add the step size, and terminate the while loop when the value in the shift register is greater or equal to the final value.

NI 5124, max points measured with 256MB memory

I want to know if there is a simple calculation that i can do to know
the maximum amount of points that i can measure with the 5124 scope.
With My application i want to measure a burst of 520 mS of signal at
ones, the signal is downconverted from 406MHz with the 5600. So
the signal is at a minimum frequency of 5MHz. This burst i want t save
completely and still be able to retrieve offline the following features:
- Frequency
- Power
- IQ
- Decode the message.
For this i need a high enough sample rate (minimum niquist). So as
absolute minimum i need 520mS signal, but it would be nice to have at
least 1 second of signal..
is there an ellegant sollution for this?

So I've implemented the change and it seems to work a bit better. I don't know if there's a drastic speed increase, but the intervals between stage motion (the only indication that an acquisition is done in the auto acquire mode) seem more uniform and on the quicker side of where they were last night.
I opted against using the "Fetch Relative To" property node in your example (which is for continuous data acquisition) in favor of the "Fetch Offset" property node used in the 'Fetch in Chunks' NI-SCOPE example (which is more along the lines of a single triggered acquisition like my situation). I also found that fetching relative to the read position wouldn't start the data stream at the normal pretrigger location, even though the position is supposed to be set to zero after each acquisition start. I would presume I would get the same waveform out using 'fetch relative to:read position' as I would using the scope soft panel, but it doesn't.
A similar problem I have now that I've messed with the "Fetch Relative To" property node is that now it seems like I have to make an extra acquisition before anything like trigger delay or number of samples to read is registered. In the manual mode, I used the "Fetch Relative To: Pretrigger" in order to get the section of data to be properly oriented in time. But it still exhibits the updating only after an acquisition has been made. Example: I setup a 1Msample acquisition at 50MS/S w/ a trigger delay of zero. I acquire and see my pretty graph. There's an interesting feature at t=8ms, so I set my trigger delay to 8ms, but I have to acquire twice in order to see my graph update with a waveform that starts near the interesting feature. Any idea why this is happening now?
Also, I've attached a screenshot of the acquisition loop. Let me know if this is approximately what you had in mind for fetching 65000 bytes (or 65000 data points w/ my I8 acquisition) at a time and streaming that to disk. Now that I look at it, it might make more sense to use another queue (like in your example) that passes the waveform ID and the chunk of data to a separate loop that is always waiting on data to write to disk. Also, when I save the files, I'd like to be able to load them and see the original Voltage/timing information on the file and I'm at somewhat of a loss as to how to include information like offset, gain, t0 and dt. Right now, even though I think it creates a weird header at the beginning of the file, I use the waveform attributes to keep this information. I ended up saving those four items in reasonably related waveform attributes, but if there's a better way you can think of, let me know.

"Semi/Non additive measure with" : "LastChild Across All Dimension" OR "LastChild Across Time and MAX across All Other Dimension"

Hey All
I am using the SQL SERVER 2008R2 standard edition so please be mindful when posting any suggestion if that will work on this edition or not.
Here is the situation: I have Cube with one fact table "Positions". Measure I am querying is "AUM" and Dimensions across user can query are combinations of {"Portfolio", "Security" and "Time"}.
I am receiving the "AUM" values at "portfolio+Security+Time" level. AUM is actually the Portfolio level value. so sample data I receive would like this.
PORTFOLIO SECURITY TME AUM
A SEC1 JAN-1 100
A SEC2 JAN-1 100
B SEC1 JAN-1 200
B SEC3 JAN-1 200
A SEC1 JAN-2 300
A SEC2 JAN-2 300
B SEC1 JAN-2 400
B SEC3 JAN-2 400
So, as shown in above example , we received same "AUM" value for a given portfolio and time. (regardless of what security value is).
And as AUM is the snapshot values, we can not sum across time as well, so if user is looking across time we need to pick Last values.
Now when user wants to view this data from cube, two different ways s/he wants to look at it.
option one: AUM at port+sec+time level. that is same as shown above in example.
option two: AUM at portfolio level only, (notice that this is across time so results are picking values for time=JAN-2)
PORTFOLIO AUM
A 300
B 400
GRAND TOTAL 700
I have applied the "LastChild" aggregation property to measure to achieve "Do no Sum across Time "behavior. but with this I also get "SUM Across Except time" and hence my AUM values get summed across Portfolio and security as
well. I have also enable Time Intelligence to enable MTD, YTD calculations.
I tried to add SCOPE statement for Security before and after the "time calculations" yet I am not able to achieve expected behavior.
here is the calculated member definition, and scope statement i have tried.
CREATE MEMBER
CURRENTCUBE.[MEASURES].[AUMNetBaseCurrency] AS
[Measures].[AUMNetBaseCurrency_Raw_Max],
FORMAT_STRING = "#,##0.00 ;( #,##0.00 )",
VISIBLE = 1 , DISPLAY_FOLDER = 'Position';
After this I have MTD and YTD time calculation for few measures including AUM.
I tried placing the following SCOPE for AUM before and after the Time calculations but it no difference in result, in fact it seems like it has no affect of scope at all due to the "LastChild" aggregate property applied on measure.
SCOPE([MEASURES].[AUMNetBaseCurrency]);
SCOPE([Security].[Symbol].[All]);
THIS = MAX([Measures].[AUMNetBaseCurrency_Raw_Max]);
END SCOPE;
END SCOPE;
so options I am thinking of but do not have clear idea how to implement those are:
0) why my Security Scope Statement are not showing any effect, and can we do something about it?
1) Can be change "SUM" behavior to "MAX" / "MIN" across all Dimension except time.
2) Is there a way to implement "LastChild" across all dimension instead only across Time.
3) Should I need to make any changes at Fact table level to achieve this ? I refer one Q&A in this forum that suggested to create such measure in different measure group but it doesn't have any clarification.
Any help would be appreciated.
Thanks

hi,
you will have to enable cache in your nqsconfig.ini file under the section
# Query Result Cache Section
[ CACHE ]
ENABLE = YES;
cache seeding is also a mechanism through which the data would be updated in the cache.

How to use external timebase for Two Edge Separation measurement with PCIe 6351

Hi
I am working with PCIe 6351 x series DAQ card.
counter measurements.
Here i need to measure the time/no edges between two edges. Falling to Raising of two signals.
I got the measurement with internal time base.
here i need to synchronize the measurements with external clock from the external setup.
so i need to use that external clock,timebase for the counters.
Any solution please..
Regards,
Hari

First, the VI you mention is NOT for STC timer/counters. Therefore, it won't work.
If you want to get the time interval between two edges, you want to use the Functions -> Data Acquisition -> Counter -> Count Events or Time VI. This will do the function you are looking for.

Unit of measure with language Key

Hello Guruz,
WHile creationd of purchase order, there is a check kept which compares the vendor communication language which gets updated in the Po header - Communucation tab with Db table T006A which holds the Unit of measurements with Language Key and pops up an error message.
It cheks the order unit in the PO, and the T006A whether the unit is maintained in the Language key as in the PO header - Communiction tab.
But while creating a unit of measurement in CUNI, we dont have the option to maintain the language key for the UOM.
In CUNI, it defaults the language key as EN in table T006A.
I need a prompt support from you guys on this issue. Please suggest how to go about with this?
Best Regards
Greg.

Hello,
When i am trying to go for the language key in CUNI, it says that the said language is 'not available in server'. I guess it is checking whether the language patch is updated in the server.
But it doesn't sound logical to maintain all the unit of measurements in all the vendor languages. Suppose if we are having vendors with 75 communication languages and we are having 50 units os measurements, so does that mean that we have to maintain units of measurements 75 X 50 times ?
Kindly provide your inputs on the issue. We are facing lots of issues with this control kept in PO header checking for the T006A with the vendor communication language.
Regards
Greg

Samples Not Acquired on NI 660x or NI 6624 Devices When using pulse width, semi-period or two-edge separation buffered measurements with the NI 660x and NI 6624 on counters 0 and 1, some samples may not be acquired under certain circumstances.

In the DAQmx 9.4 Readme the following is stated:
Samples Not Acquired on NI 660x or NI 6624 Devices When using pulse width, semi-period or two-edge separation buffered measurements with the NI 660x and NI 6624 on counters 0 and 1, some samples may not be acquired under certain circumstances.
Could anyone elaborate on this? I am particularly interested in knowing under what circumstances this problem arises for the 6602 PCI devices.
How should I understand 'NI 660x and NI 6624 on counters 0 and 1'. Is it only a problem on counter 0 and 1 for the 660x or does this only apply for the 6624 devices.

Personal recruitment How to do new measure with function call Update IT4000

Hi out there and happy new year to forum,
i want to update to implement a recruitment measure (Transaction PB40). I did it already with batch input, but i guess it's much more comfortable to do with funtion module, bapi or calsses.
After choosing the measure, the infogroup will be processed. So i guess, i just have to use the corresponding function modules to update the infotypes in a given sequence. is this suggestion right?
What are these function modules? How to update f.e. IT4000? Does anyone has a coding snippet?
Is it HR_INFOTYPE_OPERATION?
In our Infogroup there are also customer specific infotypes f.e. 9***. Can I use the sap standard function modules for "own implemented" infotypes?
I also appreciate an abap oo pattern or any similar....
Best regards,
T

But I don't think that it's possible to hire an application completly with function modules (there is no PERNR in the beginning so I would keep the BIM).
The applicants already exists in system, i just want to implement a measure with exact one click!
Otherwise there is a BAPI for applicant_create.
I'm not very expierienced focussing the implementation in pa-recruiting. I'm really looking for a good documentation or anything like that f.e. sap press.

What are the alternatives to it. (I'm not looking forward to upgrade releases or using wd4a or webgui). we are on ecc 6.0 There is already a lot of z-coding in recruitment. We are also using an self implemented e-recruiting approach

Exporting set of measures with aliases into essbase cube

We were wandering if there is an easy way to import bunch of measures with aliases into Essbase cube rather then entering them one by one?
thank you

Simplest way, would be to create a spreadsheet with the Measures and alias listed in column format.
You can organize them in Generation, Level or Parent-Child format.
Create a dimension load rule that maps the columns to properties in Essbase.
When you want to modify the Measures dimension layout, change the spreadsheet and rerun the load rule.

Error "CONVT_NO_NUMBER" while performing user measurement with USMM

Hi,
While running user measurement with USMM I am getting following run
time error.
To be specific - After preselections in USMM->system measurement->while
checking Green Check mark this error is screaming up.
Ae per Note - 1230640 :- You call transaction USMM and want to cancel
the user measurement using the cancel button (red 'X') on the dialog
box of the user measurement. However, the measurement continues and is
completed as if you had chosen the ok button (green check mark).
Above note is applied if the problem comes if we check red button
rather than green check mark.
Please suggest us the best way to procees.
ST22 details:-

Exception CX_SY_CONVERSION_NO_NUMBER
Date and Time 09/16/2008 07:42:32
Short text
Unable to interpret " 1,410 " as a number.
What happened?
Error in the ABAP Application Program
The current ABAP program "RSUVM001" had to be terminated because
it has
come across a statement that unfortunately cannot be executed.
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to
class 'CX_SY_CONVERSION_NO_NUMBER', was not
caught and
therefore caused a runtime error.
How to correct the error
Whole numbers are represented in ABAP as a sequence of numbers,
possibly
with an algebraic sign.
The following are the possibilities for the representation of
floating
point numbers:
[mantissa]E[algebraic sign][exponent]
[whole number part].[fraction part]
For example, -12E+34, +12E-34, 12E34, 12.34
If the error occurred in your own ABAP program or in an SAP
program you modified, try to remove the error.
If the error occures in a non-modified SAP program, you may be able
to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the
following
keywords:
"CONVT_NO_NUMBER" "CX_SY_CONVERSION_NO_NUMBER"
"RSUVM001" or "RSUVM001"
"START-OF-SELECTION"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
Information on where terminated
Termination occurred in the ABAP program "RSUVM001" - in "START-OF-

Build the Bar chart from Cross Tab which have 3 measures with cell refr.cal

Hello Friends. I want to Build the Bar chart from Cross Tab which have 3 measures with Actual , Plan and Forecast
But Issue here is each cell is defferent like i have to do different calculation for each cell for actual, plan, forecast
like A = Jan act/Budget actual, Where as B = Feb Act/ Jan Budg+Febbdgt_March Budget
So now when I right click to say turn to Chart it is not generating the chart
Please help how to build bar chart since i do not have 1 key figure which i can drag and drop in view structure of chart so how to handle this
                         Jan, Feb, March, Aprl, May, June
Actual                  A       B       C     D
Plan                     N       M       O     P
Forecast
SONIYA

Hi Soniya,
It will be better if you can get these keyfigures calculated from the BEx with the help of structures in the BEx.
At the report level it will be complex to create these variables and also not sure whether going to work:
But you can try something like this:
A= If (L01 Moths="JAN") then Sum (Actual)/Sum (Bud) Else 0 similarly for other months.
Then you need to create one more variable (measure) which should be plotted on the chart as:
Final Act = If([L01 Month]="JAN") Then A ElseIf([L01 Month]="FEB") Then B ElseIf([L01 Month]="MAR") Then C
Final Plan= If([L01 Month]="JAN") Then N ElseIf([L01 Month]="FEB") Then M ElseIf([L01 Month]="MAR") Then O
similarly you have to create variables for Forecast, then finally you can plot final 3 variables in the graph.
Hope it helps you.

Rohit

Configuring measures with custom aggregation for hierarchies

Can I Configuring different measures with different aggregation for hierarchies . in AWM the aggregation for measures are disabled, am I missing something.
For example
Dimension : supplier
Measure : risk score
Aggregation : maximum
Dimension : supplier
Measure : spent
Aggregation : sum

Yes it is possible. But make sure that you have turned the compression off in the cube

AC resistivity measurement with MyDAQ on TEC

Hello,
I would like to ask for advice: we would like to measure resisitivity of Peltier-elements. If we use DC method, because of the Seebeck-voltage of the element, we do not get the real resistivity value. The common method to use AC measurement in case of such devices. I would like to know, if it is possible to use a MyDAQ device for this task? As a first approach we do not need the best accuracy, this would be more as a "broken-element" test (there is usually a significant shift away from the nominal AC resistivity value stated by the manufacturer).
What would be the easiest way to carry out a simple measurement? What about if I use one analogue output of the MyDAQ lets say with 1kHz, and I drive the Peltier-element with this voltage AC source? And I connect a known resistor in series, and I measure the AC voltage drop on this. From this data, I could calculate the current, and the AC resistance of the Peltier-element? Of course I have to choose a resistor so the MyDAQ can drive the network.
what is your opinion, where to start?
Thanks!
Solved!
Go to Solution.

Hello, thanks for the reply!
Actually I am just going to replace 60 Peltier elements in a "home-made" 15 years old heat exchanger (I expect to find some mice too ). This assembly has dropped performance (heat transfer power) and also I know that, a few years ago after a malfunction with the hot side cooling fans, this device was running for a certain time without forced cooling. What is quite bad in case of Peltier-elements. I have already bought 65 brand new Peltier-modules and after I get some heat conducting paste, I will replace them. And I will have 60 pieces of old Peltier modules, to play with them
Since I have this NI MyDAQ, I thought it would be fun (and would give also valuable information) to try to measure the old elements' AC resistivity. Since this task is not like I should do often, so for first, I would not like to go for more pro solutions, I will try the MyDAQ first.
I expect that some of the modules got structural degradation during the heat shock, and this may be measurable in a shifted AC resistance.
I would do the measurement with zero applied DC voltage. These modules are Melcor PT3-12-30L (discontinued product), the nominal module resistance is about 5 Ohm.
EDIT: and would you recommend a certain circuit to try? Shell I use a known resistor for current measurement via measuring the voltage on it? Or I could use a known AC current to drive the Peltier, and I would measure the resulted AC Voltage on it?

Create new object (measure) with IIF function on BW Olap universe:mdx error

hello
i have a universe based on a BEX query
i want to create a new object (a measure) with the IIF(,,) function
i created the following select:
<EXPRESSION>IIF(@Select(Currency Type\CurrencyTypeCode)="10",@Select(Key Figures\RevenueGlobalCurrency),@Select(Key Figures\RevenueLocalCurrency))</EXPRESSION>
defined as number
where
CurrencyTypeCode is a dimension (character format)
RevenueGlobalCurrency and RevenueLocalCurrency are measure (number format)
i always have a parse which is OK but
when i want to use the object on a webi report i always have an MDX error : ...invalid MDX with .... (WIS 10901)
and advise ?
Thanks

Hi Didier,
Thanks a lot for your help.
Now it works : i do not understand why
i explain:
the correct syntaxe of my new measure is :
<EXPRESSION>([Measures].[4FVLHG7OAJMNY9WC06X6JLOZQ], [0CURTYPE].[10])</EXPRESSION>
it does not works with my "L01 currency type" BO dimension
([0CURTYPE].[LEVEL01])
when i had :
-my universe is based on a BW BEX query
-my universe has been automaticaly generated with the assistant
-the Currency Type Class was define as below:
       - 1 BO dimension object : L01 Currency Type =>
[0CURTYPE].[LEVEL01]
       - 3 BO detail objects : L01 Currency Type techName =>
[0CURTYPE].[LEVEL01].[TECH_NAME]
                                          L01 Currency Type Key =>
[0CURTYPE].[LEVEL01].[[20CURTYPE]].[Value]
                                         L01 Currency Type Long Name =>
[0CURTYPE].[LEVEL01].[[40CURTYPE]].[Value]
i always had a wrong mdx syntax error on the webi report
i updated the class with the follow
     - 1 BO dimension object : L01 Currency Type =>
[0CURTYPE].[LEVEL01] (idem)
       - 3 BO detail objects : L01 Currency Type techName =>
[0CURTYPE].[LEVEL01].[TECH_NAME] (idem)
                                          L01 Currency Type Key =>
[0CURTYPE].[LEVEL01].[NAME] (updated)
                                         L01 Currency Type Long Name =>
[0CURTYPE].[LEVEL01].[DESCRIPTION] (updated)
then it was working
Then i tried to reproduce from scratch and now it also works with the previous version of the class.
I do not understand anything
Is there something like a cache file of the MDX query (in RSRT, cache mode is set to inactive for the bex query) ?
ps: this is the same if a use webi under infoview (java) or webi rich client...

Alternate Unit of Measure with several Qty KF's

Case is as follows:
3 different plain KFs related to qty. Sales volume, net weight anddelivery qty.
All need to be dispalyed in the same report. All have different base unit of measure.
I have only one variable [YTAUNIT) for entering required unit.
Now if I enter all KFs using this same YTAUNIT variable for them each separately I get error message on the query that this is not permitted.
How should I change the structure ?
- add new variable for each KF ? (YTAUNIT1, YTAUNIT2, .....) -> do I need to change any of the ABAP codes? is there a link only picking YTAUNIT ?
Please can You give me an example (detailed) how to proceed ?
Thanks in advance
Petri

Hi,
I have worked on single variable But from the understanding of working I feel you need to create three diff variable (input var) YTAUNIT1, YTAUNIT2 ect Because they are on same base unit of measure with different units of measures. And you will have to take corresponding variable for every key figure in the calculated KF.
Just try with different variables.
Assign points if it helps.

Wrushali
