(a) The output shall be a continuous ac signal of frequency F1
3 Hertz in accordance with Drawing 2412395. Output
amplitude shall be 1.8
0.8 volts ac, with a total
harmonic distortion of not greater than 10 percent.
(b) Load impedance shall be not less than 9.5K ohms.
(2) Acquisition lambda, W1, P2-5.
(a) The output of pin W1, P2-5 shall be not greater than 0.1 volt
ac, with either the STATION switch in the OFF position or
with the ACQA switch in the OFF, two, or three position.
(b) With the ACQA switch in position one or four, and the STATION
switch in either the LI/RO or LO/RI position, the output shall
be 2.2
0.1 volts ac, at a frequency of F1
3 Hertz in
accordance with Drawing 2412395. Total harmonic distortion
shall be not greater than 10 percent.
(c) With the ACQA switch in position 5 and the STATION switch in
either the LI/RO or LO/RI position, the output amplitude
shall be 0.24 to 0.30 volt ac.
Frequency and distortion
shall be as specified in 3.4.5.2.d.(2)(b).
(d) With the STATION switch in the LI/RO position, the left-right
reference output shall have a phase shift of 25
3 with
respect to the acquisition lambda signal.
For the LO/RI
position of the STATION switch, the output shall have a phase
shift of -155
3 with respect to the acquisition lambda
signal.
(e) External load impedance shall be not less than 9.5K ohms.
(3) Electrical cage return, W1, P2-23.
(a) The input impedance for positions one through five of the
front panel ACQA switch shall be not less than 102K ohms in
parallel with not greater than 0.02
(b) The amplitude of the input signal shall be monitored by a
frequency sensitive (low pass) threshold detector. Accept/
reject criteria for the various ACQA switch positions are
shown in table VI.
(c) For ACQA switch positions three and four, the output of the
threshold detector shall enable or disable the missile audio
output, W1, P2-15.
In either of the above switch positions,
an accept status shall disable the missile audio output (0.1
volt ac maximum output voltage). A reject status shall enable
the missile audio output in accordance with the setting of the
front panel AUDIO switch (see 3.4.5.2.d.(4)).
