22.214.171.124.1 Laser feedback voltage. With the azimuth boresight knob set
to 4.0 and 36 1 Vrms at 400 Hz, item 2.2 of table I, applied to J6-W and
J6-X, the laser feedback voltage between J6-S and J6-Y shall be not less than
5.94 V peak-to-peak.
126.96.36.199.2 Tachometer out put. With 36 1 Vrms at 400 Hz, item 2.2 of
table I, applied to J6-W and J6-X, the tachometer voltage between J6-W and
J6-V shall be not less than 2.5 Vrms.
188.8.131.52.3 Boresight knob travel - elevation. The elevation boresight
knob travel shall be not less than 5.0 mils from the boresight position.
184.108.40.206.4 Boresi ght knob travel - azimuth. With the mirror positioned
to achieve the boresight condition and the azimuth boresight knob adjusted for
the null condition, 10 mV rms at J6-Y, the azimuth boresight knob shall be
further adjustable CW and CCW to obtain a feedback of not less than 295 mV
rms, 5.0 mils, at J6-Y. With CW rotation of the boresight knob the feedback
voltage shall be in phase with AC Ref 1, (item 1.5, table I), and with CCW
rotation the feedback voltage shall be out of phase with AC Ref 1.

18.104.22.168.4, the resolver feedback voltage shall be as specified in table IV.
3.3.17 Sight system. (See 22.214.171.124)
126.96.36.199 Resolution. Resolution on the optical axis shall be not greater
than 7 arcseconds at 12X and shall be not greater than 10 arc seconds at 6X.
At 0.7 field, the resolution shall be not greater than 15 arcseconds at 12X
and shall be not greater than 30 arcseconds at 6X.
