Output Port
This field selects the RF generator’s output port. Higher RF generator
levels are available at the DUPLEX OUT port than at the RF IN/OUT
port.
Operating Considerations
CAUTION Applying reverse RF power to the DUPLEX OUT
connector can damage the instrument. (A message is
displayed when an overpower conditions occurs.)
Whenever possible, use the RF IN/OUT connector when
testing transceivers to prevent damage from accidental
transmitter keying.
If a reverse-power condition triggers the internal
protection circuit, remove the reverse-power signal and
reset using
Meas Reset (press and release the Shift key, then
the
Hold key) or turn the Test Set off and on to reset it.
Maximum signal levels at the RF IN/OUT, DUPLEX OUT,
and ANT IN ports are printed on the connector panel.
Exceeding these levels can cause permanent instrument
damage.

Pk Det To
This field selects the signal source for the peak detectors. This allows
you to bypass certain sections of the AF analyzer’s circuitry when
making ac-level measurements.
• Filters analyzes the signal after filtering through Filter 1.
• De-Emp analyzes the signal after filtering through Filter 1 and
Filter 2, and after de-emphasis.
