2-2.2 Knobs
Squelch
Squelch control. Clockwise rotation increases
the receiver threshold signal level above which
the squelch opens.
Volume
Controls volume of the speaker audio.
Bright
Intensity adjustment of the display. Clockwise
rotation results in higher intensity.
Tuning
Incrementally changes the digit over which the
cursor is currently sitting. Clockwise rotation of
the tuning knob increases the number;
counter-clockwise rotation decreases the
number. This provides the equivalent of an
analog control for numeric cursor entry locations.
2-2.3 DISPLAY
9 c
m x 11 cm bit-mapped LCD. Provides data,
operating controls, and instructional information.
Displays in digital, analog, and bar graph forms.
NOTE
The LCD has a screen saver feature that
reduces intensity after approximately
30 minutes of inactivity. Press any key to
restore the display.
2-2.4 Connectors
2-2.4.1 Front Panel Connectors
RF IN/OUT
Provides RF input signal to the analyzer's internal
monitor or output signal from the analyzer's
internal generator. Also provides combined in-
put/output in DUPLEX mode. Contains the RF
wattmeter load. This is the only front panel con-
nector to which RF power may be applied.
GEN OUT
Provides a high level generator RF output port
isolated from the Monitor input.
DO NOT APPLY RF POWER.
ANT
Input port for sensitive monitor receiver.
Useful for off-the-air measurements.
DO NOT APPLY RF POWER.
NOTE
The GEN OUT and ANT connectors are
protected from overload by an RF fuse in-
stalled in the front panel connector. This fuse
may be accessed by unscrewing the front
portion of the BNC connector from the panel
using a 7/16 inch deep socket wrench.
Replacement fuse part number is
GG-6530277C002.
CAUTION
The RF fuse leads must be trimmed to a length
of .48 +
.02 inches and the tips cut to a point
to facilitate installation.
VERT/SINAD DIST/DVM COUNTER IN
Combined input port for oscilloscope vertical,
SINAD meter, DVM/counter, Distortion meter,
DVM, and frequency counter inputs.
