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 "Reference Frequency: External". 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 "Reference frequency: Internal".
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.
Warning
It is forbidden to load input signals on the output port to avoid damage or abnormal function.
3. Trigger IN: If spectrum analyzer uses an external trigger, the connector receives the rising of falling edge
of an external trigger signal. The external trigger signal is feed in spectrum analyzer by BNC cable.
