Old Device restarts when receiving any command

[Tarrant]

Hey,

I have connected 4 devices on a GPIB to USB adapter. I can see all 4 of them at the interface and 3 of them are working as they should (can send commands and get the expected answers).

The 4th one "Programmable Pulse Current Source P4000" of the company "fastest" reboot itself whenever it get´s a command and causes therefore a connection timeout. (Also it doesn't turn to remote because of the restart).

It shows the same problem, when it is the only connected device.

The Current Source is about 20 years old and the company doesn't exist anymore, also we don't have a manual for that source.

Are there some old devices, which need a special command to get to remote instead of reboot? Or is maybe this old device damaged on the gpib-interface?

Thanks for your time and help,

Tarrant

HI,

does this happen with any command? Did you try the "*IDN?" command?

This should work even with old devices.

Best,

Anna

Hi Anna,

I solved the problem. It happen with every wrong command and for this device also *IDN? is a wrong command, because it is older than these commands got standardized. I got lucky to find an old program, which was forgotten by the institut members, where some commands where used to talk to the device and with them it works fine.

Thanks for your help anyway 😉

Best regards,
