Rear Panel Description
The diagram below illustrates all rear panel connections. For further
explanation of labels found on the rear panel see the section on safety
considerations on
page 48 .
1.
TRIGGER 2 OUT
provides a transmitter tester trigger output. This is
used to synchronize other test equipment with the
transmitter tester.
2.
TRIGGER 1 OUT
provides a transmitter tester trigger output. This is
used to synchronize other test equipment with the
transmitter tester.
3.
EXT REF IN
allows the input of a 1 to 30 MHz external frequency
reference signal. The external reference frequency
must be entered by the user.
4.
10 MHz OUT
provides an output of the transmitter tester’s internal
10 MHz frequency reference signal. This is used to lock
the frequency reference of other test equipment with
the transmitter tester. This is a switched output.
5.
TRIGGER IN
The external trigger allows external triggering of
measurements. The external trigger accepts an
external trigger signal between
−
5 and +5 V, and has a
nominal impedance of 10k
Ω
. For more information on
triggering, see page 79 .
