We have DSO7032A scopes, 8 of which had CAL PROTECT switch issues.
IN-CIRCUIT testing suggested that the switch was OK.
BUT, it was not.
Out-of-circuit testing revealed a BAD SWITCH. All 8 were BAD!
Take a look at this Instructable created to address this issue named:
Agilent DSO7032A Oscilloscope - Repair of CAL PROTECT Switch
See if this helps. Good luck.
