NORM supplies No. 1 and No. 2 stabilator amplifier-pitch rate gyro output

signals through test set connectors J1 and J2, to No. 1 and No. 2 stabilator

amplifiers, respectively. NORM also supplies No. 1 stabilator amplifier-filtered

pitch rate output signal through test set connector J3 to SAS amplifier. Signal

from No. 1 stabilator amplifier-pitch rate gyro can be monitored at STAB 1

SNSR and STAB 1 SIM test points. No. 1 stabilator amplifier-filtered pitch

rate output signal can be monitored at SAS SNSR and SAS SIM test points.

GND supplies ground from test set through connectors J1, J2, and J3 to No. 1

stabilator amplifier, No. 2 stabilator amplifier, and SAS amplifier inputs,

respectively. These grounds can be monitored at STAB 1 SIM, STAB 2 SIM,

and SAS SIM test points. SIM STAB 1 & 2 supplies variable dc simulation

signal selected by NOSE DN/NOSE UP control through test set connectors J1

and J2 to No. 1 and No. 2 stabilator amplifiers, respectively. These simulation

signals can be monitored at STAB 1 SIM and STAB 2 SIM test points. This

position also supplies a ground through test set connector J3 to SAS amplifier.

This ground can be monitored at SAS SIM test point. SIM STAB 1 supplies

variable dc simulation signal selected by NOSE DN/NOSE UP control,

through test set connector J1 to No. 1 stabilator amplifier. This simulation sig-

nal can be monitored at STAB 1 SIM test point. SIM STAB 1 position also

supplies No. 1 stabilator amplifier-filtered pitch rate output signal through test

set connector J3 to SAS amplifier. This filtered pitch rate signal can be moni-

tored at SAS SIM test point. SIM STAB 1 also supplies ground through test

set connector J2 to No. 2 stabilator amplifier. This ground can be monitored at

STAB 2 SIM test point. SIM STAB 2 supplies variable dc simulation signal

selected by NOSE DN/NOSE UP control, through test set connector J2 to No.

2 stabilator amplifier. This simulation signal can be monitored at STAB 2 SIM

test point. SIM STAB 2 also supplies ground, through test set connectors J1

and J3, to No. 1 stabilator amplifier and SAS amplifier, respectively. These

grounds can be monitored at STAB 1 SIM and SAS SIM test points. SIM SAS

1 supplies variable dc simulation signal selected by NOSE DN/NOSE UP con-

trol, through test set connector J3 to SAS amplifier. This simulation signal can

be monitored at SAS SIM test point. SIM SAS 1 position also supplies ground

from test set through connectors J1 and J2, to No. 1 and No. 2 stabilator

amplifiers, respectively. These grounds can be monitored at STAB 1 SIM and

STAB 2 SIM test points. SIM SAS (WO) supplies variable dc simulation sig-

nal selected by NOSE DN/NOSE UP control through test set connector J3 to

SAS amplifier. This simulation signal can be monitored at SAS SIM test point.

SIM SAS (WO) position also shorts out capacitor in SAS amplifier, allowing

gain checks to be done using steady state dc simulation signal from NOSE

DN/NOSE UP control. SIM SAS (WO) also supplies ground from test set

through connectors J1 and J2, to No. 1 and No. 2 stabilator amplifiers, respec-

tively. These grounds can be monitored at STAB 1 SIM and STAB 2 SIM test

points.
