27
Low level RF input port for the sensitive receiver monitor on the R8100. Used for off-the-air and other
low level measurements where the RF power is below 0 dBm.
CAUTION
Do not apply high level RF Power to the Antenna port.
Lower front panel connectors Needs new photo
RF In/Out
Bidirectional port that routes RF input signals to the analyzer's internal monitor or output signals from the
analyzer's internal generator. Also provides combined input/output in Duplex mode and contains the RF
wattmeter load. Note: This is the only front panel connector to which high level RF power may be applied.
RF Gen Out
A high level generator RF output port isolated from the Monitor input.
CAUTION
Do not apply RF Power to the Generator port.
Meter In
Combined input port for oscilloscope vertical, SINAD meter, Distortion meter, and DVM/counter
functions,
Mod In/Out
When configured as an output, this port provides a composite sum of all internally generated modulation
signals applied to the R8100 RF carrier. When set as an input, audio signals external to the R8100 can be
used to modulate the RF carrier. Note: The audio signals must equal +/- 1Vpk to provide a reference for
accurate display of the applied modulation level.
