Compare two pulse counts

Hello,
I'm trying to compare two simultaneous pulse counts using a cDAQ-9172 chassis, a 9401 card, and LabVIEW 8.2. What I want to do is set up a single output pulse that lasts for, say, 1000 incoming pulses on ctr0, and then use that single output pulse as a gate on ctr1 to count the input pulses that it sees during those 1000 pulses on ctr0. In other words, I want to synchronize the two counters, and as soon as ctr0 reaches 1000 pulses, they should both stop so I can compare the two counts. The issue is slightly complicated by the fact that both counter inputs are very noisy and require a pulse width filter in order to be read properly.
I more or less understand what needs to happen conceptually, but I'm at a loss for how to make it happen. A simple walkthrough would help enormously. Alternatively, if there's a better way to accomplish this, that would be helpful as well.
Thanks.

Thanks for the advice. I set up a program (attached) that tries to implement basically what you suggest, but there are still problems. The main issue is that it gives me an error -200141 message telling me to change the data transfer mechanism to DMA. When I set up a channel property node to do this, it tells me that DMA is not available.
The other concern I have involves the pulse width filter on the counter output task. The 1000 pulse signal is extremely noisy, and without any filtering, the noise will increase the frequency by a significant amount. I've set up the filters as you can see in the program, but I have no idea whether I've done this properly.
Any further help you could offer would be greatly appreciated.

Analogue Signal Pulse Count

I am using CDAQ with a NI9229 4 Channel analgoue input card.
I have a sensor that outputs an analogue 5v square wave signal. The pulses are triggered from eithe a north or south pole of a magnet. I have an aluminium wheel with 30 magnets, all magnets are in opposition to each other. when the wheel is rotated the output is a square wave.
My magnet wheel is rotating at 182° per second. Over 360 degrees there is 30 magnets. Thus making the sensor switch 30 times.
The time to revolve the wheel one revolution is 1.978 seconds.
I have set up the NI9229 to the following
- sampling rate is set to 25kS/s So to record the data for one revolution it works out as 49450 bits.
- Have set the trigger levels for recording a hi or lo pulse to 2.7 and 0.7 volts.
50000 samples would be two seconds worth of data which would be more than 360° of rotation of the magnet wheel.
The problem I am having is that my pulse count changes between 30 and 31. But as I am only recording 1 revolution of data there is physically only 30 switches. Do you know why I am getting a change of 30 and 31.

I think I know what the problem is now but don’t know a way around it.
I have attached two screen shots. One shows that the rising edges are counted as 15 and the falling as 16 the other shows both are 15. This is due to where it starts to take data I believe.
For detecting the rising or falling edge I compare the data to 4.0 or 0.5v If its below 0.5 then sends a hi signal and counts 1, if its above 4.0 it sends a hi signal and counts1.
But depending on when it starts taking data the signal is already a falling or rising edge. Comparing one bit of data on a rising edge to see if its below 0.5 will send a hi as it hasn’t started to rise as shown in the first picture.
Is there a better way to count pulses

How do you cyclicly trigger data acquisition after n pulses counted

Hello all, please forgive my ignorance because I am very new
to lab view and data acquisition. I am working on a system which is going to
scan an object and produce an image. The gimble that I am scanning the object
with is an X-Y type of gimble with stepper motors on each axis. The stepper
motor controller will output pulses real time to indicate the real time
position of the gimble in each axis. What I need to be able to do is count
pulses from the stepper motor controller and then output a trigger pulse to
trigger the data acquisition in a buffered mode when N number of pulses have
passed and then generate another pulse to stop the acquisition after another N
number of pulses have passed. The controller puts out 10,000 pulses per degree
of travel. The velocity that I am traveling at is 20 degrees per second, so
timing here is really important. I need to be able to utilize the speed of the
daq card and not so much the speed of the computer to iterate through a loop. I
have tried using the count down feature in the NIDAQ MX library but it does not
appear to be useful to me. I set it up and it will count down but once it hits
zero it continues to count down. My expectation was that it would either
restart the down count or it would stop. I was expecting some sort of trigger
event to take place once the count reached the zero point but I did not observe
any sort of event taking place. Once again my knowledge and background is
really limited so I could be missing something really fundamental here. I have
tried using some of the legacy functions which would enable me to do exactly
what I want to do but they do not seem to work with my daq card. I have a NI
PCI-6122 and if anyone has any knowledge on how to get this type of card to
talk to some of the non MX functions I would be more than happy to hear how. It
seems to me though, that I am limited to the MX functions which I can not
really translate into what I have learned I can do with the legacy functions. I
thank you all once again for taking the time to read this I and I will
appreciate any and all responses that can be helpful.

I have run a few more tests and obtained some data per the request of a telephone support engineer. I have some scope screen shots that might be able to shed some light on what is going on. I will provide a brief description of what I discovered before I show the resulting data. I discovered that using the number of up ticks and down ticks suggested does not yield the right timing for the clock pulses that I will need for triggering my data acquisition. When I use 55 low ticks and 2 high ticks as my settings I end up getting a pulse every 32 pulses read on the PFI line. I get the same results when I interchange the numbers, for example, when I set the program up for 2 low ticks and 55 high ticks I get the same resulting one clock pulse per 32 pulses on the PFI line. I started playing with the numbers and come to find that I was able to generate a pulse every 57 pulses in this setup. I set the high ticks to 2 and the low ticks to 71 and once I did that it generated a pulse every 57 pulses in. The results are not ideal though, a number of things happen within the first second of operation. One mode of operation the clock output pulse latches after a few pulses generated. Another mode of operation that I noticed was that it would generate n number of pulses and then just stop even though the program was still running. The results I am getting are not reproducible when it comes to the long-term operation of the clock pulse generation but the bottom line is not matter what happens the end result after 1 second is not what is expected. I will show below screen shots of my program and also scope shots for the respective modes of operation.
Front End interface
Block Diagram
55 High ticks and 2 low ticks results
55 low ticks and 2 high ticks results
77 Low ticks and 2 high ticks results
Undesired Latch after 1 second of operation
N number of pulses generated and stopped while program was still running
It appears the the long term operation (and when I say long term I mean after a second) is intermittent, it either latches high or low after a random number of pulses are generated on the clock output. I am not sure why this is happening. The one setup that I came up with that generates a pulse every 57 pulses is not going to work for the setup that I have I think I would have to reduce the 71 to 69 in order to compensate for the two pulses that happen while the output pulse of the clock is high. To be honest I have no idea what is going on and I am starting to wonder about my daq card. Being that it is not really reproducing the same results I am starting to think maybe something is wrong with it. Another possibility is that it might be the bnc 2110 that I am using. I will try another one tomarrow and see if this problem persisits. I am leaving now so I won't be able to try that as of yet but I wanted to pass this info and data along such that maybe you will notice something and be able to lead me in the right direction. Thank you again for all of your help.

With this code, i can check only one time the cells. If I clear cell2 press enter, and then I write in cell2 again it code doesn't work.
How can i do it with other method?
Thanks in advance

Okay, say the above is my table, how do I compare two cells in a row for two numbers? Say I wanted to find out if row A2 contained a 7 and a 28?
"A2" is an address for a single cell, not a row. Its current content, assuming no empty rows above or empty columns left of what's shown, is "Jan 4, 2011". Perhaps you mean Row 2, or the range B2:G2.
Assuming that you want to know 'if' (or 'how many times') two specific numbers occur in the range of cells from column B to column G in a single row, COUNTIF is the function you want.
Place the two target numbers into cell I1 and J1.
Enter the formula below into I2:
=COUNTIF($B2:$G2,I$1)
Fill the formula right into J2, then fill both down to row 4.
You'll get a count of the occurrences of each number.
If you want only a "Yes" (both numbers appear in the range) or "No" (neither of the numbers appear, or one appears but not the other), use this variation (in I2 or J2):
=IF(AND(COUNTIF($B2:$G2,I$1)>0,COUNTIF($B2:$G2,J$1)>0),"Yes","No")

Compare two characteristics in Query

Hi Experts,
I have to compare two characteristics in Query fields like (A)Approved Level of Job(contain values like 01,02,03,04) and (B)Required Level of Job(contain values like 01,02,03,04).
Now I have to do these calculations
If A>B =1
If A<B =0
And also in other case
If A=b then value 1
Of A =/= B then value 0
Please let me know how I can achieve this.
These values could be in A,B,C,D instead of 01,02,03,04 then in that case how I will calculate these comparison.
Thanks
Take care

so my CKF will be
A>B/5 means 3/5=60%
I also need to know how i am going to count A and B too.

How to compare two oracle database schemas

hi all,
i want to compare and find out differences between two oracle databases. The comparison should be made on between table definition,table data,primary and foreign keys, packages and functions.
Is there any management console or tool embedded in the oracle enterprise manger?
it is really appreciate if anyone can point me towards wright direction asap.

REGEXP_ compare two tokenized strings

Hi,
I need to compare two fields (from two tables), to see if any of the tokenized contents match.
I have two tables with a "name" field, but the names might be incomplete or in random order. To get a match, I just need 1 part of both to really match, for example "John Doe" should match to "Doe J.".
Something like:
SELECT names1.name, names2.name
FROM names1, names2
WHERE INSTR(names1.name, REGEXP_SUBSTR(names2.name, '[[:alpha:]]+')) > 0
But the statement should consider all tokens, not just the first one as in the example.
Any suggestion on how to achieve this?
Thanks,
K.

The performance of the regexp_instr in the where clause is terrible ... I stopped working out other scenarios, because the conclusion will be the same:

Hi.. all I want to compare two universes of different data mart to check the table structure. Can anybody please tell me how to compare two Universes of different Datamarts?How i can achive this usinig BusinessObjects Enterprise XI Release 2 ??
Thanks in advance.

Good day. Is there into Pages the possibility to compare two documents? In order to reveal changes.

Hi iMayner,
I don't know of a way to easily compare two documents in Pages. Maybe there is an app to do this, but I don't know of one.
What you can do in Pages is to open both documents, resize the windows and drag them side-by-side on the screen. Pages 5 has a limit on how narrow you can make the windows, so this may be a bit of a pain.
The first step would be to show the Word Count in both documents. (Pages 5.5.1 Menu > View > Show Word Count, or click on the View button in the ToolBar and Show Word Count). If the Word Counts are the same, you have **some** confidence that the documents are identical, but no guarantee.
An example of two short documents with different word counts:
Document A (33 words)
The quick brown fox jumps over the lazy dog.
Don't count your chickens until they hatch.
Don't cross your bridges until you come to them.
An apple a day keeps the doctor away.
Document B (34 words)
The quick brown fox jumps over the lazy dog.
Don't count your chickens until they have hatched.
Don't cross your bridges until you come to them.
An apple a day keeps the doctor away.
To home in on that difference, copy and paste each document into a column in a spreadsheet such as Numbers or Excel, so that each paragraph becomes a cell in a column. Turn on Wrap text in cell.
The different heights of each cell (paragraph) become apparent.
Happy Christmas!
Regards,
Ian.

Pulse count fieldpoint

Hi! I need to write a VI with a pulse counter employing fieldpoint. Here's my problem: I have an energy meter with pulse output. I can set pulse frequency, pulse lenght and number of pulses for kWh. I have to read the signal from that instrument but I don't really understand how. I mean, I do not have to measure the frequency of the pulses 'cos I already set it, I'd rather read the signal from the meter in a specified period of time and count the number of pulses in that time. How can I do that?
I can both connect the meter to a cFP AI-110 or cFP CTR500. There are mainly two things I don't understand:
-how can I count the pulses in, let's say, 30 s?
-how can I define the reset condition?
Thanks!
Valeria

Valeria,
CTR500 is the best solution. Have you verified that the pulses from the energy meter are compatible with CTR500 inputs? If so, the two counter method will give you the best results. The first counter creates a window of known width which is then used to enable another counter that counts the pulses. There is an example .vi that ships with LV called "Frequency Measurement.vi" that demonstrates the 2 counter method. Instead of calculating frequency you will need to calculate energy.

How to compare two signals

I would like to compare two singals from NI-DAQ (ch0) and NI-Function generator (ch1).
One(ch0) is 500 Hz and the other(ch1) is a little bit complex (sine and then square pulse 250 times faster than 500Hz).
In so many times, I tried to get a trigger mode in ch0 or ch1.
The comparison points of two signals are starting and ending point(phase) to check the synchronization.
Is it possible to compare them by oscilloscope?
Is there a suitable instrument to compare them conveniently?
Best,
labmaster.

Hello labmaster,
Could you tell me a little more about what you are trying to do? What devices are you using to generate your signals, and where are you trying to start and stop the aquisition? The way you would go about triggering on a 3rd party oscilloscpe will depend on the triggering options supported by that scope.
If a pure hardware-defined oscilloscope does not give you the kind of triggering you need, you might consider looking into using a NI digitizer. Not only do our digitzers support a large variety of triggering methods, you will be able to choose which samples to display through use of LabVIEW.

Compare two different iPhoto Libraries

Is there any program that could compare two iPhoto Libraries and let me know the difference between them? I've got two libraries, they should have the same pictures, but for some reason one is 80GB bigger than the other one.
I know there are duplicates, but 80GB seems a lot for only duplicates, so I want to compare both of them and see what pictures are missing.

How many photos does iPhoto indicate in each of the libraries? Open the Photo mode, do a select all and see how many are indicated at the bottom of the window. See if that corresponds to the number beside the Photos icon under the Events library. Be sure to turn on Item Counts in iPhoto's General preference pane.
Which is the larger: the old or the new?

How to Compare Two Strng without .equals() method

Hiii,
How to compare two Strings with out .equals method if there are white spaces in between these string it should be avoided..
eg: ab cd ef g is equal to a bc de fg
Please give me the logic or code..
Your help will be appreciated

dude find the code without the equal method
public class test {
     public static void main(String args[])
          String str = "ab cd ef g" ;
          String str1 = "a bc de fg";
          char []ch = str.toCharArray();
          char []ch1 = str1.toCharArray();
          int counter =0, counter1 = 0;
          while(counter < ch.length && counter1 < ch1.length)
               while(ch[counter]==' ')
                    counter++;
               while(ch1[counter1]==' ')
                    counter1++;
               if(ch[counter] != ch1[counter1])
                    break;
               counter++; counter1++;
          if(counter == ch.length && counter1 == ch1.length)
               System.out.println("true");
          else
               System.out.println("false");
}

Trigged generation of two pulse trains

I have to write an application that will generate two equal pulse trains (with a given phase difference) on two different counters when I recieve a trigger signal. I'm using a 6063daq-card. If anyone have an related example, or some hint on how to solve this (elementary problem) please let me know.

Hi OG,
Although this functionality is present on NI-TIO counter/timer chips (NI-660x boards) by use of an initial delay within the counters (could program a delay equal to the desired phase shift) this is not available on DAQ-STC chips (E Series boards). This is because DAQ-STC counters do not support an initial delay in pulse train generation mode (driver doesn't support it).
The only way I see this happening is if you use the frequency generator on the E Series to generate your first pulse train (output on the freq_out pin) and use your two main counters to generate 1) a triggered and delayed pulse which will gate 2) your second counter which is a pulse train of the same frequency. To get the phase correct, your delay of the pulse should be equal to t
he desired phase shift of your pulse train period and should be gated/triggered by one of the rising edges of your frequency generator pulse train. The actual pulse width of this single pulse should be made as large as possible (or should toggle the output - see the 2nd knowledge base linked below). I have included a couple good references to get you started. Hope that helps. Have a good day.
