Equipment Required
Calibration PROTECT/UNPROTECT switch
The 1670G-series logic analyzers have a calibration
PROTECT/UNPROTECT switch on the back panel. This switch must
be set to UNPROTECT before new calibration values from the
operational accuracy calibration can be stored to nonvolatile RAM.
Set up the equipment
1 Turn on the logic analyzer. Let it warm up for 30 minutes if you
have not already done so.
2 Facing the front panel, reach around to the lower right corner on
the back of the logic analyzer. Flip the PROTECT/UNPROTECT
switch to UNPROTECT (flip the switch up).
