Output Port Pk Det To

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.
