TABLE 1-7. BTS SWITCH INFORMATION (Continued)

FUNCTION

SWITCH

NOISE INHIBIT - Alternate action pushbutton - When enabled

1A2S1O

inhibits random noise ECM in LRU-1 under test.

SW-3 INHIBIT - Alternate action pushbutton - When enabled

1A2S11

inhibits SW-3 ECM in LRU-1 under test.

CP - Alternate action pushbutton - When enabled inhibits

1A2S12

pulse program in LRU-1 under test.

LAMP TEST - Pushbutton switch - When pressed provides a

1A2S13

ground return to light the status signal lamps and

forcing function lamps on status panel.

SWITCH COAXIAL - Enabled by the YIG FILTER IN-OUT switch

1A2S14

on control panel.

IN Position - YIG filter and driver control (FL1)

is connected into the RF path of status panel.

OUT Position - YIG filter and driver control (FL1)

is disconnected from RF path.

1A2S15

SWITCH COAXIAL - Enabled by the YIG FILTER IN-OUT Switch on

control panel.

IN POSITION - YIG filter and driver control (FL1)

is connected into the RF path of status panel.

OUT POSITION - YIG filter and driver control (FL1)

is disconnected from RF path.

FREQ SEL (F1-F2-F3) - Three position toggle switch - Selects

1A3/1A4S1

the low, mid and high RF frequencies directed to

the UUT.

1A3/1A4S2

CS FREQ - Two decade thumbwheel switch- Sets conical scan

(CS) frequency in 1 Hz steps from O to 99.

OUT SEL (PULSE/CW) - Two position toggle switch - Selects

1A3/1A4S3

either pulse modulation of RF signal or Continuous

Wave (CW) RF output to LRU-1 under test.

1A3/1A4S4

PW - Two decade thumbwheel switch - Sets the pulse width

from 0.1 to 9.9 microseconds in 0.1 microsec steps.
