RF IN/OUT
This Type-N connection is used to output signals from the RF generator and to input RF
signals.
CAUTION Overpower Damage — Refer to the Test Set’s connector panel for maximum input power
level. Exceeding this level can cause permanent instrument damage.
If the RF power at the RF IN/OUT port exceeds allowable limits, a loud warning signal
sounds and a message appears at the top of the screen. If this occurs, disconnect the RF
power, reset using
Meas Reset
(press and release the
Shift
key, then the
Hold
key), and
allow the Test Set to cool off for approximately 2 minutes before making any other
measurements on this port.
Operating Considerations
This port must be used when measuring TX (RF) power.
Signals ≤60 mW can be input to the ANT IN connector for all RF measurements except
TX Power.
This port can be selected on the RF ANALYZER, RF GENERATOR, CDMA
GENERATOR, CDMA ANALYZER, CODE DOM, or SPEC ANL screens.
SCOPE MONITOR OUT
This connector provides an external output from the AF analyzer.
Operating Considerations
The Scope To field in the AF ANALYZER screen determines the source of this signal.
For more information see the “Scope To” on page 214.
The level is not affected by the front-panel VOLUME knob.
Output impedance <1 kΩ
