PEN LIFT OPTION (A-5)
-
Provides mounting holes for BNC connectors used with special modifications or
options.
When Pen Lift Option is installed, these
2
terminals provide contact closure during
sweep "ON" time. This option operates only when the Front Panel SWEEP
TIME Selector is set to the 100-10 SEC. position.

After the RF signal passes through the RF circuit of the
device under test
it
must be demodulated before being con-
nected to the DEMOD
IN of the Model 2001. If a demodu-
lator is not a part of the device under test, one must be
added externally. (See Figure

The input impedance
of the demodulator must present the proper load to the
RF circuit being tested. The Wavetek Model

Detector is recommended for 50-ohm applications.
