I recently purchased an old 8753E and would like to recalibrate and test the unit as much as possible/reasonable.

Can anybody tell me what calibrations and tests listed in the service guide are recommended and SAFE to do?

Or shouldn't i touch the device at all to not worthen things?

I only got an 3 GHz spectrum analyzer, so tests that require an external power meter etc. are not possible for me.




If I'm right, the following calibrations/tests, listed in chapter 3 of the 8753E service guide, should be safe to perform?
