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.
