Bug: Issues in setting 1 microsecond scale in tektronix oscilloscopes

[Albert.Geven]

Hi Nathan and Mathan

Indeed reading the graph into the pc can solve the missing cursor vi's but especially when the traces are long it consumes more time.

So if the driver can be updated with some cursor vi's it would be very nice.

Dear Albert,

Thanks for the post. Yes it would be nice if the cursor vi's comes along with the drivers.

Can you suggest me any method to measure the values of t1, t2 from the waveform in the previous posts. Sorry for repeatedly asking this again and again. But i need a solution to my problem.

look in the palette signalprocessing/wfm measurements

Dear All,

This is what i tried. I captured waveform from the scope and stored in the waveform graph and did the processing in LabVIEW 2009.

I got the exact peak of one waveform using the cursor properties of the waveform.

So if i add 13.5 MHz or 74.04 nsec (that is the frequency), i will get the exact peak of next one and so on until i reach the 90% value in the given waveform. But in adding up to find the next peak, due to the approximate value, this is not finding the appropriate value. Can you please help me in finding out the value of t1?

Thanks a lot,

Mathan

I expect to do a peak find on the datavalue's not the cursor values.

So what are you trying, are you trying to calculate the expected next peak and have rounding errors. Or do you try to find the next peak from the data and have a resolution problem?

[Mathan]

Dear Albert,

I got good suggestion from Thomas how to measure t1 here. Thanks a lot for all your support.

[Edit: Anybody from NI can explain why there are scaling problems and some functions missing in the new set of drivers(Tektronix 7000 Series.)]

Hello Mathan,

       We will look into the issues that you have reported and consider adding the cursor VIs to the newer driver.

Thanks,

Thanks a lot NathanT

Hi Mathan

thanks for pointing.

Did you check with  the extract single tone informatio.vi

It is very good in calculating the exact frequency but you need a few more cycles.

Hi All,

I have added Configure Cursor.vi in the Configure folder and also the palette. This version has not been released to ID net. Most of the cursor functions are implemented on this VI and to get the Programmer's Manual, click here. All cursor functions are on page 26 to 28. If you think there are more useful functions that have yet to be implemented, please let us know.

Thanks,

Alvin T.
