Hi Steven,

I can't really explain what you're seeing, it's certainly unexpected.

Would you be able to put these signals on a real-time scope so we could see what that looks like?

Hi Denis,

There's a few things you could improve in your code:

1) There's no reason to do both *RST and FAC
2) DATA:SOU is for curve queries, it's irrelevant here
3) MEASU:AUTO EXEC is for jitter measurements, it shouldn't be used here
4) MEASU:MEAS1:CCRESU:ALLA:MEAN? is for getting the mean value of a measurement across multiple acquisitions, this is not what the procedure is asking for. Instead, you should use MEASU:MEAS1:VALUE?

Hi Makis,

Please make sure you're on the latest version.
If this issue remains, I'd ask if you could share a setup file.

Glad to hear you got it working and thanks for sharing how you did it!

Hi,

I think that's almost correct, only thing is that you should use the MEASUrement:ADDNew command instead of ADDMeas (which is also a valid command but won't let you set the index).
Apart from that, I think your code should work for what you want. Do note that you didn't set the edge types (rising or falling), so they will be set to their defaults.

Hi Makis,

From my quick testing, neither of those happens when a clipped measurement is taken. Instead, it clears out the whole histogram and doesn't start rebuilding it until the channel stops clipping.

Hi Justin,

The P6015A does not use a dielectric fluid, instead it uses a silicone based insulator that does not need to be replaced/refilled.

The P6015 (non-letter), does use a dielectric fluid that can be refilled, more information is available here: https://w140.com/tekwiki/wiki/P6015
Please do note that R-114 has been a banned product for over 30 years and the probe can still be used (although derated, as specified in the manual) without the fluid.
 

Hi Makis,

If you notice, when your signal is outside of the screen, you will get clipping warning on the channel tab and measurement badge. This is because you're overdriving the ADC and any captured signal is invalid.
Additionally, any measurement taken is essentially undefined behavior.

No, the calculation doesn't depend on vertical scale (except for unavoidable side effects like differing noise, resolution, etc)

Hi,

I am not aware of any issues. If you're experiencing any issues then please make sure you're on the latest firmware: https://www.tek.com/en/support/software/firmware/2-series-mso-nonwindows-firmware-v2638
If the problem remains on the latest version, then let me know and I will submit a report on it.

Hi Gil,

As discussed here, the TFW file format does not contain timing data, so no, I don't think there is a way for you to define the sampling rate in the file.
For a csv, the AFG ignores timing data in the file (all it cares about are the sample values), so you have to manually set the sample rate. In the advanced menu this can be done directly through the menu you can pull up at the bottom. In basic mode, there's no explicit way to do this, you just have to calculate the correct period from your number of samples in the file and desired sample rate.
