I have a Rigol DG1022Z function generator I bought new 7 years ago and when I get access to a GPSDO I would like to tweak the frequency accuracy of the Rigol. Don't want to touch anything else, just the frequency. Could someone point me to a step by step guide how to do this?
I don't think it has noticeably drifted, just want to make sure it is as accurate as possible.
