Function

CPU DISPLAY (cont)

PROGRAM ADDRESS

Six-digit indicators that display the unit-under-

(A1U4 thru A1U9)

test digital processor 16-bit program ROM address

in octal form.

INSTRUCTION

Eight-digit indicators that display the 24-bit

(A1U11 thru A1U18)

instruction output of the addressed unit-under-test

digital processor program ROM in octal format.

OVFL

LED indicator that displays the state of the ALU

(A1CR19)

overflow register of the unit under test:

LED on = overflow register set, LED off = overflow

CARRY

LED indicator that displays the state of the ALU

(A1CR20)

carry register of the unit under test: LED on =

carry register set, LED off = carry register cleared.

RUN

LED indicator that displays the state of the

(AlCR1)

digital processor unit-under-test: LED on = digital

processor running, LED off = digital processor halted.

FAULT

LED indicator that lights when a unit-under-test

(A1CR2)

digital processor failure occurs.

COMMAND DISPLAY:

OCTAL DISPLAY

Six-digit indicators that display the unit-under-

test output word response to a SER. INT. CONTROL

test or COMM. PROC. TEST. This display is in octal

format.

DESIRED DELAY LINE

LED indicators that display the correct delay

CMD

line command generated by the df control. These

(A2CR1 thru A2CR12)

data are in binary form: LED on = 1, LED off = 0.

RESULTING DELAY

LED indicators that display the delay line preset

LINE CMD

(DLP) CMD generated by the df control. When the

(A2CR13 thru A2CR24)

unit-under-test is functioning normally, these data

match the DESIRED DELAY LINE CMD data. These data

are in binary form: LED on = 1, LED off = 0.

ANTENNA SWITCH CMD

LED indicators that display the antenna switching

(A2CR25 thru A2CR36)

command (ASC) generated by the df control test

command in binary form: LED on = 1, LED off = 0.
