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.
