Problem with the new STG2008: Sweep light is on

Dear MCS,

I have recently purchased a new STG2008 stimulator. In the past, I used exactly the same device loaned to me by Scientifica. When I got our own stim, I just thought I would plug it instead of the previous one and it would work. However, when I switch the power on, the Sweep light turnes yellow even if the stim is not connected to the PC. Moreover, the PC and MC Stim do not see the new stim through the USB connection. Could you tell me what could be the reasons for these problems?

Many thanks,

Maksym

The internal circuit board had come loose during transportation. It was reconnected by our local distributors (Scientifica), and the device sent back to the customer.

Do you have any feedback that STG2004 gives unstable voltages for a long term period? And do you know the best way to see and record signals from the stimulator except for a oscilloscope (because we can't record)?

Dear Fari,

an Oscilloscope would be exactly what you need. as an alternative you might try to stream the STG output into any DAQ system and plot the result. However this would add more components to the test and is not my first choice for such a test...
