I recently acquired a HP8752A . This is a wonderful VNA.
But I have a question:
Each time when I have stored a calibration in internal memory I loose the entire calibration when the VNA is switched OFF.
-- is this normal behaviour ?
I also checked that the internal buffered RAM had its 5V by the buffer capacitor, it keeps the volatage over days !
-- has anyone an idea what goes wrong or do I wrong?

The instrument is working the way it is supposed to according to Table 10-6 on page 10-86 of instruction manual 08752-90054 which is available from Keysight.
Do you or anybody know a workaround how to store & retrieve cal data for the HP8752A ?
As I know disks and floppys are not available anymore, what to do then ?
Thank you XMO to have pointed me to table 10-6.
This table was not on my radar before
Look at the GPIB toolkit from KE5FX. The VNA utility may do what you want and the ability to capture screens is also nice to have.
thanks XMO this is a good hint , I just check it what I could find there and this looks very applicable
thanks for the valuable answer

A 9122 HPIB interfaced disk drive would be a nice addition to the analyzer.
thanks fur the concrete valuable hint XMO
Your Flash EEPROM to store measurement files could be corrupted. This is a common problem on older instruments.
