MIL-C-48490B(AR)
3.3.1.4 Lasing pulse timing. During laser firing, the time elapsed
between the start of SCR trigger and the start of A-trigger, measured at J2-P
and J2-n shall be as specified in figure 1. (See 4.6.2.4)
3.3.1.5 A-trigger waveforms. During laser firing, the A-trigger wave-
forms, measured at J2-m and J2-n shall be as specified in figure 2. (See
4.6.2.5)
3.3.1.6 Malfunction 3 signal. The voltage measured at J2-f shall be as
follows: (See 4.6.2.6)
a. 4.2 1.2 V after laser firing.
b.
.002 0.2 V with the voltage at J2-S removed and the logical zero
type-A signal (item 3.1 of table I) momentarily applied to J2-R.
C.
4.2 + 1.2 v with the logical zero type-A signal (item 3.1 of
table I) momentarily applied to J2-e.
3.3.1.7 Range and video signal. With the digital type-A input signal
(item 3.1 of table I) applied as specified in figure 39 the range and video
signal outputs shall be as specified in figure 4. The signals may recur at a
period of l.0 0.1 microseconds (ins). (See 4.6.2.7)
3.3.1.8 Reset signal. After laser firing, the reset signal as specified
in figure 5 shall appear at J2-c and J2-d. (see 4.6.2.8"
3.3.1.9 AGC inhibit. With the input to the receiver aperture covered and
the digital type-A input signal (item 3.1 of table I) applied as specified in
figure 6, the AGC inhibit output between J2-b and J2-V (rtn) shall be 29.0
4.0 V. With the type-A input signal removed, the output shall be 0.0
1.OV. (See 4.6.2.9)
3.3.1.10 Ranging. Range conditions of the assembly shall be as follows:
(See 4.6.2.10)
a.
The minimum range shall be 200 meters.
b.
The maximum range shall be 5000 meters.
c.
The range accuracy shall be plus or minus 10 meters.
d.
The range resolution shall be 20 meters,
3.3.1.11 Minimum range inhibit. With the optical input signal to the
receiver aperture attenuated 40 + 1 decibels (db) for Target No. 36 1 or 36 1
dB for Target No. 3B and the logical zero type-B signal {item 3.2 of table I)
applied to J2-w, the second video pulse signal as specified in figure 7 shall
not be present with the laser fired at Target No. 3A or 3B (item 8 of
table X) and the Range readouts shall display 9990, 9995 or 000 and the
RETURNS readout shall display 0. (See 4.6.2.11)
