Waveform & Digitworth in a box

Hello,
I use an D/A Converter and get some volt worthes in a 2D Array (first Index, second worth).
Now I wont to read the actual worth and put it to a box.
Unfortunately the waveform should dimension it
self, because I don´t know how long a
mesurement take and i need the hole graph.
I use Labview 7.0.
thx

LV7.0_Developer_DE,
i am not sure if i understand you correctly, but i repeat what i understood:
you are acquiring data via a dataacquisition-device (infact, you are
using an A/D-Converter then, analog-to-digital). you retrieve the data
in a 2D array, where the first column represents a incrementing number
(index) and the second column contains the values of the measurement.
now the point i do not understand: in LV, you simply connect the signal
you retrieve to a waveformchart or - graph to display it. there is no
need to "to read the actual worth (value would be the correct word here) and put
it to a box". if the chart or graph displays it the wrong dimension
first, you should transpone your array first. if you dont want to
display the index-column, you can simply remove it with the
array-functions in LV.
all in all, i believe that you want to acquire the data continuously.
so please take a look into the example finder of LV under
DAQ->Analog in->continuous acquisition with chart. this is of
course only applicable when you are using DAQ-hardware from NI.

Problem with Plot Starting at Zero Seconds.vi

In document with ID: 4KTFBLE9 an example vi is offered. Its name is "Plot Starting at Zero Seconds.vi". I have problems in "borrowing" the function labeled "Waveform Chart", comprising a box with the text "XScale Multiplier". When I transfer this function to another vi, the function is transmutated to another function. What happens, and what am I doing wrong?

This is a property node and it will only link directly to items in the same VI. If you move it to a different VI, it will turn into a plain property node.
If you have another waveform chanrt in the other VI, you can right-click the copied proeprty node and select "link to..." and select the local waveform chart.
If you want it to act on the "other" wavform chart, you need to make the second VI a subVI and wire the reference to it via a connector.
If you want to create a new such property node, simply right-click the waveform chart and select the desired property.

LabVIEW Champion . Do more with less code and in less time .

I am trying to acquire several cycles of a waveform and save it to an excell file.

Only one or two (I don't remember which) of the values shows up on the excell spreadsheet, the spreadsheet remains otherwise empty. I know that the waveform is being captured by the DAQ because it is graphed, and it looks fine. If someone could point to where I have gone wrong and offer some suggestions, I would greatly appreciate it. Also, if there are some obvious indications that I am missing some necessary understanding of what is going on within my vi, feel free to enlighten me.
Thanks for all your help.

The reason is that you are trying to wire a 1D arrray of WDT (waveform data type) to the file box. WDT is a special data structure where are stored not only the signal readings but also t0 (the time stamp = date of the first data point) and delta t (the time increment between to points). You need to reorganize the data before saving to a file. Use the "get waveform components" (in the waveform subpalette) to separate the time stamp from the data.

Audio waveform sync and drifting problems on imported AIF's in FCP 6

Hi FCP people,
I have been having problems importing bounced audio files into Final Cut Pro 6. I've done a search and can't find anything to help me yet, so here's a new post.
This has happened on two projects: both files are 16-bit 48KHz.
1) Having finished an edit (HDV 1080/50i timeline) I exported my audio into Soundtrack to finish the audio mix and normalise, and then saved the bounce. When I imported that back into FCP the audio seems to drift. What is particularly strange is that the waveform looks like the audio is in the right place, but the sound comes out before it should. V. Weird!!!
2) The second file was sent to me from another system. I was given a FCP file (I have a copy of the source footage on my HD and reconnected it). They also sent me the audio mix. Once again, this file seems to drift out of time, yet the waveform looks right.
When I import the video file and audio bounce file into FCPv5 it works ok.
Can anyone help me on this? Or is this a problem with FCP that others are also having?
Many thanks, Tim

Hi Zak,
many thanks for your reply, i have contacted Apple and taking your advice and using compressor i have converted the codec H.264 to Apple Pro Res 422 for interlaced material.
I have imported this file and when i drag once again from the viewer to canvas i get the standard box asking to change the sequence to match the clip.
I am still getting the red line above the timeline and bleeping as audio.
any idea?

Audio waveforms not showing up in viewer

Using Final Cut Pro 6. When double clicking an audio track, it doesn't show up correctly in the viewer. The top half doesn't come up at all and the bottom doesn't look right. No idea why this is happening or how to fix it. Tried dumping the audio waveform cache, but that did nothing. Help ASAP would be much appreciated as this system needs to be used to edit something with audio right away. Thank you!

I am having the same problem. I am running FCP 6.0.4 and when I double click on an audio clip in the timeline, there is no waveform in the viewer. Just a big black box.
In the past I have deleted the waveform cache folder and trashed preferences. But this isn't working anymore.

Waveform chart, plot and Dynamics Data and double data

Hello everyone !
I would like to get separate plots on the same waveform chart.
Actually, I am simulating 4 signals (but in reality, it would be signal from sensors) and I would like to get 4 plots.
In the end, I get 3 plots and no 4 plots.
It is very strange... Yet, I have selected 'Stack plots' and '4 plots shown'.
Actually, I can see the last data has been merged with the first one.
How can I fix that ?
Thank you !

I'm not sure how you got into this state but try going into the chart properties (right click front panel chart and click Properties from menu) and under the appearance tab, unclick "stack plots", unclick "Show digital displays(s), hit "OK", then go into properties again and reselect those two boxes and hit okay. It should correct the problem.
All statements are my opinion and worth every cent you paid for them.

Real time waveform graph in while loop

Hi
I have a VI which includes a subVI that reads data from an oscilloscope and presents the output in the form of a cluster made up of the initial time t(0), a time interval delta t and an array of voltage readings.
This cluster can then be wired to a waveform graph in the usual way. All of this is situated within a while loop in my VI and on each iteration of the loop I obtain a waveform graph of the voltage readings starting at the same time t(0) and ending at the same time t. However I want my graph to begin at a time t(0) when I set my VI running and then continuously acquire and build up the data on each iteration of the while loop so after my VI has finished executing I have a complete graph of all the voltage readings acquired after the set number of iterations of the loop. I know on the Express X-Y Graph VI you can double-click the node and deselect the box that says 'clear data on each call' - if I could do this in my case that would be great but I can't use an x-y graph because I have an array of y-values to plot on each iteration.
If anyone can help me out it would be much appreciated - I'm sure there must be an easy solution to this but I'm going out of my mind trying to find out what it is!
Many thanks,
Bex.

As usual, you have several options.
You can use an XY Graph by generating the X values yourself. This will ensure that you place the data exactly where you want it on the X axis. This is fast, but does involve a memory cost.
You can use a Waveform Graph with a waveform input instead of the cluster you are using. Use the Build Waveform primitive instead of the bundler to make your waveform. Set the t0 values to the appropriate values (negatives do work, as do small numbers - time is in seconds, use the To Time Stamp primitive to convert from DBL to timestamp). Finally, you need to set the Waveform Graph to use the t0 values. Pop up on the Waveform Graph and make sure Ignore Time Stamp is not checked. Depending on your version of LabVIEW, you may have to pop up on the graph or the axis. When you unselect Ignore Time Stamp, you will probably want to reformat the X-axis again. The Waveform Graph clears data at each iteration, so you will need to replot all your data each time. Just create an array of waveforms and keep adding to it. The t0s will put the waveforms in the right places. Yes, this may cause memory problems.
Finally, you can use the Waveform Chart, which does have memory. Create the waveforms like you did for the Waveform Graph and send them to the chart. It will remember what was sent to it from run to run. Make sure you set the Chart History Length (pop up on chart and select Chart History Length...) to long enough to hold your entire data. You can use a property node to get the data back at the end, if you need to.
Good luck!

Want a constant time axis in waveform chart

hello,
my time axis in waveform chart is changing .how can i keep it constant say 1-100 .the whole point of this is to make waveform chart luk like a CRO.please need help.
thanks in advace
naveen.rabelli

I don't think what you're asking for is possible, due to the nature of the chart - it accepts Y values and inserts the X value automatically. Offhand, I can think of 3 solutions -
The bad one - constantly change the offset by moving it backwords. You will probably have flickering.
The workaround one - Paste a text box over the first number saying 1 and another over the second number saying 100.
The probably most correct one - Use a XY graph. Just have a 1D array of 100 elements and append it to a second 1D array with 1..100. Wire the 2D array into the graph terminal.

Graph cursor box diamonds

I have a graph with the cursor legend visible. There is a box with four diamonds next to the cursor legend, and the four diamonds allow the users to move the cursors. Since I allow cursors dragging on my graph, there is really no reason for the diamonds to appear. Is there a way to get rid of the diamonds boxes? I can't just move them out of the way, since the graphs are inside a tab controls, and there is no where in the tab control where I can hide the diamond boxes.
Kudos and Accepted as Solution are welcome!
Solved!
Go to Solution.

You can move it behind the waveform control or behind the cursor legend
Just select it by itself and use the arrow key.
You may have to move it to the back (Ctrl-Shift-J)

Set waveform chart size to value 1000

Is there any possibility to set the size of waveform chart buffer to value >1000 in LabVIEW?

Hello Konigusko,
you've got to right-click on the chart and choose "Chart History Length", then this little Dialog box appears.

How to split n merged waveforms coming in one AI

I have one AI channel that Im useing to recieve n waveforms on. How would I got about splitting up these waveforms so I can look at they're indiviual attributes? They will be square waves with unique duty cycles, pulse widths, periods, and amplitudes. I know its some what of a big problem, Ive been looking around for VIs but turned up with no luck. Anyone have any ideas to put me in the right direction, or have done similar things?
Thanks
Mark

Hello again!
I was wondering....do you have access to the original clock signal at all times? It looks like your higher frequency square wave is an exact multiple of the lower one...if so, there might be a way of re-dividing the signal based on that clock. Do you need to perform this function in real time, or process it later. Perhaps if you can give me the actual source for this signal, there might be a more elegant way to do this than with the waveform operations.

Measuring waveforms through shared variables

Dear All,
I am trying to measure 4 waveforms from a signal generator, I am
transferring the waveforms through a shared variable on my host.vi from
the target.vi. But the signal is not coming as it is. I am attaching
some screen shots, I have tried changing the parameters of the shared
variable but it does seem to help. I am also confused about the options
that become active when click theI check box of the "use
buffering" option.
The screen shots are zipped.
Thank you very much.
Sincerely,

Dear Nick ,
I am sending the program in zip format including the files of the
waveforms that I have saved. I used the select signal express VI but it
does not seem to select the different waveforms. There are two .dat
files. One contains all the 4 channels and the other
contains 1 channel.
Thank you for the really fast response.
Sincerely,

Recorded waveform not visible in region

Hi.
I had to re-record a backing vocal track on a song I am working on.
I was experimenting with the Sample Editor on the original track and, basically destroyed it.
However, the new track doesn't show a waveform in the region.
It was visible while recording and is visible in the Sample Editor and it plays ok.
After recording, a small dialogue box appeared which said it was analyzing the track and then the waveform subsequently disappeared.
Can anyone help me with this?
Cheers for now.

Dear jari,
Thanks for your reply..
Currently i have APEX in node 1 and DB along with listener in node 2.
Using DADs.config file in APEX(node1) im trying to connect to the DB(node2). Im not sure with the listener im using. Im using the listener which comes with the DB. Whether is this the APEX listener.

If free disk space reaches 45 MB, the Manage Temporary Folder Reserve Space dialog box appears

This was a big problem for me in AA2 but I thought it was gone in AA3. It has only just started happening in AA3. I have gigabytes of space yet this dialog box is only supposed to appear when you have only 45mb of space available?
It seems to happen when a serious amount of editing of files has taken place. I mean sliced & diced and tuned almost every sylable of a vocal line.

Ok - This has happened a couple of times since my last post on the subject but this time I took some readings.
When doing an "export" the Manage Temporary Folder Reserve Space (MTFRS) appeared after doing a vocal edit/comp - I mean a real lot of slicing and dicing in multitrack view (I have no control over the client's vocal ability).
Details
OS XP/SP2
Audition on C drive 92gb free
Recorded files (24/44.1) on H Drive 131gb free
Primary temp on H drive
Secondary Temp on E drive
There is no undo history showing in the "undo History" area
There are a large number of files listed in the "waveform" area
The temp files totalled about 80mb and are the same size (with the exception of AudxNRJI.tmp which goes from 65.5mb and is then deleted) when the program exits.
I understand that there are limits to everything and that this is more of an annoyance than anything.
It would be good to know just exactly it is that triggers this situation.
PS Just about to post when I did some more sums.
It maybe that Peter K. Larson is correct about the 4gb undo history.
I note that the MTFRS shows "134319 free" space on the primary temp drive and after AA exits there is 131gb. While some of these figures are not exact (file size vs space on disk etc) there is some anomaly.
Do we know where the undo history is stored on disk - I would assume the temp drive?

How to control individual channel of signal generated from digital waveform generator?

Digital waveform generator has 8 channels. I need to generate two different signals to HSDIO. How to modify and control two different channels? Also, how to translate pin outs from PXI-6541 to channels? I need to control signal into pin 1,3,29,and 31 individually.
Thank you!!
Solved!
Go to Solution.

You must combine your individual data into an array. The digital waveform is simply a digital representation of the binary array. It still boils down to bit 0 of each array element going to channel 0 (or the first channel you specify in Create Dynamic Channels). The next bit goes to the next channel. My last post is quite clear. To display the array in binary, right click on an array element, then select Display Format, then select Binary. You can also right click on the element, select Visible, then select Show Radix to display the small b before the number. One more thing, in the Display Format window, uncheck the box next to Use minimum field width. Then set the numeric just under the box to 8. Then select Pad with zeros on left in the box below.
You should not use waveforms until you learn more about how the HSDIO operates on input data. It isn't hard to combine waveforms, but it also isn't as clear as using an array of U8 or U16 or U32.
Trying to explain further. The first number to be writen to the HSDIO will have this effect: Bit 0 (LSB) of the number gets written to the first HSDIO channel you specify. Bit 7 goes to the 8th channel you specify. If you don't specify 8 channels, the bits get ignored. So wiring in one number will produce only one bit on each channel. In other words, the number already combines the bits of all the channels you specify. You don't combine anything yourself. Look again at my picture on my last post. By wiring in an array, you cause a bit pattern to be generated.
I hope this is more clear.
