Channel enable/disable started behaving weird...

[DrBwts]

It was all working fine before Xmas but now whenever I uses j.setchannelenable(True, True) the channels sometimes turn on & off but always raises the exception UnexpectedReplyError(ret)

It doesnt seem to matter which channel I'm enable/disabling I sometimes get what I asked for but always get that exception.

Things I've changed, I'm now running from a virtual environment which has QCodes in it that needs Python 3.8 or above, will this effect the functionality of your code?

Thanks for your feedback. Two questions: - do you only have an issue with that specific command? Or do other commands also give that exception? - What version of python do you use? Kr.Message ID: ***@***.***

All the commands return the exception. When I put them in a try: .. except: ... they all do their jobs except the change frequency method that does nothing.

I have just tried on an ubuntu 20.04LTS with python 3.8.10 and python 3.9.5 and both seems to work correctly. The error you get indicate that the module does not receive a ":ok" after issuing a command to the device. Can you try the following debug commands. (You should get the following answers) >> j.DEBUG_readregister(0,0) b':r00=60.\r\n' >> j.DEBUG_writeregister(0,100) b':ok\r\n' >> j.DEBUG_readregister(0,0) b':r00=60.\r\n' Note, that changing the frequency does not work is normal as the method first calls a "self.getmode()" before changing the frequency. If that command fails, it will not continue, so the frequency is never set. Kr.
