Re: freezes in stopped mode with slow time-base

Tried the college Picoscopes on home PC running XUbuntu and found same freeze problem when timebase is 5 seconds per division or slower. Mini Gigabyte motherboard with integrated AMD processor Description: Ubuntu 16.04.2 LTS Release: 16.04 Codename: xenial amd64 Same problem with 2203 & 2205 Picosco...

Re: freezes in stopped mode with slow time-base

Hi Hitesh
Using the original light grey (Picoscope provided) lead did not solve the issue.
I was using a longer lead originally belonging to a printer.
Handy to have a slightly longer lead but I guess its another variable that could cause issues.

Re: freezes in stopped mode with slow time-base

Hi Hitesh,
I think I was using a dark grey coloured USB lead.
I am making the dangerous assumption that USB leads are relatively inter changeable.
Will try it with the slightly unusual looking Picoscope provided lead and let you know what happens.
Many thanks,
Mark

Re: freezes in stopped mode with slow time-base

Hi Hitesh, The USB was plugged directly into to PC. We tried using different usb ports at the back of the PC and also using the ones at the front. We also tried it using a similar XUbuntu PC and always got the same symptoms. Maybe our PC architecture is unusual (they are all the same make). I'll tak...

freezes in stopped mode with slow time-base

I’m having a difficulty with Picoscope running XUbuntu on our college physics lab PCs Picoscope works at higher time-base speeds but freezes in stopped mode when time-base is slowed down to 10seconds per division or below. Picoscope can be unfrozen by closing closed down the program and reopening bu...

Re: how do I invert a channel

I've just saved the default Picoscope settings from my Windows PC and copied the default.PSSETTINGS file from the Windows PC to a Linux PC. An invert channel I created on the Windows PC is now available on the Linux PC (and it works) so my problem of how to invert a channel is solved. Surprisingly t...

Re: how do I invert a channel

Thanks for the workaround Hitesh, 8) I’ll experiment with creating custom probes using a windows laptop and copy the setup file. Our students are investigateing the current voltage relationship of inductors and capacitors with a range of frequencies. I'm using a 1K resistor as a shunt to measure cur...

how do I invert a channel

I would like to invert a channel using PicoScope for Linux but can’t figure out how to do it. In the Windows version I can define a probe with a scale factor of * - 1 but I don’t think can define a probe in the Linux version. The Linux version allows me to scale a channel but it does not seem to acc...
