Restoring factory settings for all modes
In addition to the PRESET function key (see “Using the front panel” on

function. This function resets all modes to their factory default settings
and returns you to the spectrum analysis mode. In order to restore the
factory settings for all modes proceed as follows:

Factory Settings softkey. The Factory Settings menu
appears.

Preset All softkey. A message will be displayed asking you
to confirm that all modes should be reset.
4Press E
NTER to confirm the process. All modes will now be reset to
their factory settings.
Improving the frequency accuracy
The 9102 Handheld Spectrum Analyzer has an internal time base that
is used to generate the internal frequencies for both the receiver and
the optional tracking generator. The accuracy of the internal time base
is specified in the data sheet for the 9102.
If necessary, the frequency accuracy can be further improved by using
an external, high-precision time base. The time base should consist of
a stable frequency of either 5, 10 or 13 MHz. This reference clock
signal should have a power level of at least 0 dBm and should be fed
to the E
XT. REF. IN/ EXT. TRIG. BNC connector (see “EXT. REF. IN/ EXT.
T
RIG. connector” on page 15).
