DUPLEX OUT
The duplex output is an output for the RF Generator and Tracking Generator.
Operating Considerations
•Type N
• Output impedance = 60
Ω
• The RF Generator's output is selected in the Output Port field. This field is
available on the CONFIGURE, CDMA REVERSE CHANNEL SPECTRUM, analog
RX TEST, DUPLEX TEST, RF GENERATOR, and SPECTRUM ANALYZER
screens.
CAUTION: Connecting an RF source of >200 mW to this connector can permanently damage the
instrument.
EVEN SEC INPUT
This input allows the user to synchronize the Test Set’s CDMA frame clocks with
an external trigger. The input must be a positive edge TTL signal, and must be
present when the Test Set is turned on.
Operating Considerations
The input must be a positive edge TTL signal. When the Test Set is powered on,
the frame clocks will align to within 2.4 and 3.25
µ
s
after the trigger.
