Connects an external frequency reference signal to the analyzer that
is used to phase lock the analyzer for increased frequency accuracy.
When the analyzer is equipped with option 1D5, this connector must
be connected to REF OVEN connector.
The external frequency reference function is automatically enabled
when a signal is connected to this input. When the signal is removed,
the analyzer automatically switches back to its internal frequency
reference.
Connects to the frequency reference input of an external instrument
