3.5.14 Elapsed time indicator. With POWER SUPPLY cable W1
connected to control assembly connector J2 and +28 ± 0.6 Vdc applied
to cable W1, W1-C (+), W1-D (ret), the elapsed time indicator shall

a.
The control assembly shall be in the Pulse condition.
b. With the FUNCTION SELECT switch in the RF MONITOR
position, the RANGE SELECT switch in the R3 position, and the PHASE
CONTROL at midrange, the RF LEVEL attenuator shall be adjusted such
that the digital display (DVM) indicates +2.500 ± 0.020.
c. With the control assembly in the Pulse condition, the
digital display (DVM) shall not vary more than ± 1.200 for RANGE
SELECT switch positions R1, R2, and R4.
d. With the control assembly in the Pulse condition, the
digital display (DVM) shall not vary more than ±0.500 when the PHASE
CONTROL is varied from one extreme (counter clockwise) position to
the other extreme (clockwise) position.
e. All requirements shall be measured for all positions of
the FREQ SELECT switch.
3.5.16 Clutter signal characteristics.
a. All clutter signal characteristics are to be measured
with an internal RF power calibration (Pulse) accomplished prior to
(within 30 seconds) of any measurement unless otherwise indicated.
b. An internal RF power calibration (Pulse) shall be
accomplished by adjusting the RF LEVEL dial such that the digital
display (DVM) indicates +2.500 ± 0.025 with the RF FUNCTION switch in
the RF MONITOR position.
c. All clutter signal characteristics shall be measured
with the MODE SELECT switch in the SELF TEST position unless
otherwise indicated.
