Or share a screenshot of the settings

Hi Gislain,
I was able to get an FFT with the TBS2kB on Tekscope; could I see the settings you have when you click on Math 1? Could you check where the Source is set to?

Hi Kyle,
Both the MSO24 and MS4kB have 8 bits of vertical resolution (2^8 = 256 voltage levels, so "2 decimal places" worth of resolution), so that's a limitation of the scope itself rather than some memory/USB protocol limitations.
You can try using Hi Res or averaging signal values; the horizontal column/TIME does not have to do with the vertical resolution.

Hi Pawan,
Using your example range; if you had 5V/div and 10 divisions, the vertical range would be 50V.
With the 8 bits, there would be 2^8= 256 voltage levels represented across 50V. 50 Volts/256 levels = 0.1953125 V per level.
The scope may use some bits to detect clipping on the signal though.
As for the programmable amplifier, what scope are you using/referring to?

Hi Martin,
Copying over the reply to the ticket that you sent in:
Are there any other VISAs downloaded to your PC? There is this bug where TekVISA needs to be the first VISA installed if you're using others (like NI-VISA). Does the MSO46 show up in TekVISA, even if not in TekScope?
Does the scope show up at all in the windows Device Manager (even if it isn't labelled as MSO46B)? Maybe try a few different USB cables as well, preferably USB 3.0 with a ferrite bead.
We will start from here and try to narrow down where the issue is occurring.

Hi Hernani,
No, the 2-series does not have a direct printing option. You can save to a flash drive and print the .png from there.
It might also be easier to write a script or use
Tekscope Utility, if you have USB or Ethernet connection to your PC.
You can directly save scope images to your PC and print from there.

Hi Sowmya,
You can read an image file but in order to decode it on the PC side, you'll still need some kind of script because FILESYSTEM:READFILE sends the raw data-- it's not going to just automatically show a .png in the Talker/Listener terminal.
If you want a program that can do that, I would recommend Tekscope Utility: https://forum.tek.com/viewtopic.php?t=140382

Hi Ramesh,
You can save the screenshot, you just need to send a scope.read_raw() after the FILESYSTEM:READFILE command because it sends binary data to the PC.

Hi Sowmya,
You also have to read the raw data after the FILESYSTEM:READFILE command.
I've edited Afonso's python script he previously posted for the 6-series for the TBS2000B.
1) Replace the VISA resource address with your scope's.
2) You should be able to find the .png saved under "TBS2000B_%Y%m%d_%H%M%S.png" after running this script (or feel free to change it so it doesn't generate a file name based on date/time.)
Best,
Iris
