Overview of Rear Panel

1. 10MHz Reference Input: Spectrum analyzer can use internal reference source or as an external
reference source.

If the instrument detects that the [REF IN 10MHz] connector is receiving a 10MHz clock signal from
an external source, the signal is automatically used as the external reference source. The user
interface status displays "Freq Ref: Ext". When the external reference source is lost, exceeded or
not connected, the instrument reference source is automatically switched to the internal reference
and the measuring bar on the screen will show "Freq Ref: In".
Warning
It is forbidden to load the input port with a signal that does not meet the rated value, and ensure
that the probe or other connected accessories are effectively grounded to avoid equipment
damage or abnormal function.
2. 10MHz Reference Output: Spectrum analyzer can use internal reference source or as an external
reference source.

If the instrument uses an internal reference source, [REF OUT 10 MHz] connector can output
10MHz clock signal generated by the instrument's internal reference source, which can be
used to synchronize other devices.
