Control Fields for Analog Measurements
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.
