As per the subject, our E8257D is responding very slowly on ":STAT:QUES:POW:COND?" query.
It takes about 10 seconds until value returns and it seems intermittent behaviour.
Thanks in advance.
The first thing that comes to mind is to check for other settings you have running on your instrument. Often times when multiple status registers/settings are enabled, the PSG could be busy doing other operations before it answers your SCPI command, which could help to explain why the behavior is intermittent.
There was a semi-recent firmware update that sought to fix a problem with the un-leveled power command.

This could be a possible contributor to the delay. Make sure your firmware is the most recent version: C.06.25 . Find instructions on how to update your firmware here: PSG Signal Generator Firmware
