HP 83480A - Mainframe Calibration

Mainframe Calibration
Mainframe calibration improves timebase accuracy. The calibration factors are
stored in the instrument's nonvolatile RAM.
NOTE
Mainframe calibration should be done on a periodic basis (at least annually), or if the temperature
since the last mainframe calibration has changed more than 6 5

C and measurements of the highest
accuracy
are required.
The procedures
and equipment
needed
to
perform
a
mainframe
calibration
are
included
in
the
optional
