The following test procedure measures the test set gain for one
frequency point. This procedure must be repeated if the frequency or
hardware con guration is changed.
The gain of the test set is measured over de ned frequency ranges
with the test set con gured with the appropriate cables and lter.
The following table summarizes those hardware con gurations. See
Figure 3-5 and Figure 3-6 for hardware locations.

HP 84125C download utility disk is generated during factory
calibration of the HP 84125C system and is shipped with each system
and is speci c to that system. The disk contains amplitude correction
factors for the test set and the three available antennas.
The download utility disk contains the DLP and a MS-Windows utility
that allows you to restore calibration data or modify antenna data
if needed. The utility combines the test set gain factors with the
antenna correction factors and down-loads the data (via GPIB) into
the spectrum analyzer's AMPCOR registers. The correction factors for
Table 3-2.
