PicoScope Bug

Post by setti »

Hello,
I've managed to use with success the deskew math function in time-based mode under PicoScope. However, when I try to do the same thing in spectrum mode there are no spectra displayed in the screen!!!
I am using the latest stable version of PicoScope (6.14.54) under Windows 10 (64bits).
Regards

Can you post a .psdata of what you have done.

Now I am not in my lab but this issue can also be seen by Signal Generator.
Setting the time delay as 1/4 of the time period (2.5ms) yields the signal called Ashift. However when I try to visualize its spectra nothing is displayed in the screen!

This type of maths channel will not work in the spectrum view.

If you look at the time domain picture you will see that there are gaps in the data at the start of the trace due to the time shift. The calculation of the maths channel is performed post data collection, hence the gaps, before drawing on the screen. Spectrum mode performs a software based FFT calculation on raw data collected from the device, before any post processing, and there is no mechanism to pre process the data for doing this.

I've tested this type of maths channel in PS 7 early access and it works.
The problem comes with the fact that PS6 handles these gaps in data as NaN so the spectrum cannot be done as well as related measurements like THD.
One thing that I cannot accept in PS7 is its inability to print vector graphs (pdf or postscript) as opposed to PS6. Only rasterized (bitmap) figures are available!!! and just one function in AWG demo (only sinewave function)
I have tried to export psdata from PS7 to PS6 but without success! :(

Hi,
Monitoring 3 channels: A,B and C.

A for frequency: OK
B for minimum value: OK
C for peak-to-peak: OK but it registers as a measurement for channel B

Channel B registers as having two measurements: minimum value and peak-to-peak

Channel C is not registered in the legend on my computer screen.

BUG somewhere?

It seems that this problem is related to 64-bits OSs, I've tested the PicoScope version 6.11.12 under Windows XP (32-bits) and it has worked!
