4-34. DESCRIPTION OF MAINTENANCE CONTROLS, INDICATORS, AND SWITCHES. (CONT)
CONTROL OR INDICATOR
Two-position switch, when placed in RT position, allows
position, functions controlled from control-indicator site.
XMTR LOCAL indicator lights when LOCAUREMOTE switch
Is in RT position. XMTR REMOTE indicator lights when
LOCAUREMOTE switch is in IND position.
ANT PLZN switch
Two-position switch selects either circular or linear
REMOTE switch in RT position).
DS5301 and DS5302 ANT
DS5301 indicator lights when circular mode of polariza-
tion is selected at receiver-transmitter or control-
indicator site. DS5302 indicator lights when linear
mode of polarization is selected.
SCAN MODE switch
Five-position switch selects any of five modes of antenna
scan operation when in local mode of operation.
Three-position switch selects linear (LIN) ftc or loga-
rithmic (LOG) ftc video In OFF position, ftc video output.
circuit is disabled and video is amplified linearly.
Ftc switch is used to break up video clutter while in
local mode of operation.
Monitors various BITE signals as selected by MONITOR
switch in local mode of operation.
Twenty-four position switch selects receiver-transmitter
low-voltage power supply and antenna data to be indi-
cated on MONITOR meter, when in local mode of
In ON position, reduces receiver gain for radar targets
at close ranges. Used during local mode of operation.
EL TARGET control
Adjusts monopulse operation of receiver in local mode of
operation. When rotated clockwise, targets and ground
clutter become narrower in vertical plane on elevation
IF GAIN control
Controls receiver gain for five types of antenna scan
operation while in local mode of operation.
ANT SERVO switch
Four-position switch controls azimuth antenna tilt and
elevation antenna servo position when in local mode.
