4.6.10 Maximum ranging test. Apply 37 1 dB attenuation at
the receiver aperture input. Perform a laser firing (4.6.1.3) at the
target (item 1 5) specified in table V. Observe the output at J1 -e to
determine compliance with 3.3.1.9.
4.6.11 Minimum range inhibit and TPG inhibit test. Attenuate
the input signal to the receiver aperture 37 1 dB, apply the digital
type -A logical zero to J2-f, and fire the unit at the target described in
3.3.1, 10. Verify that the requirement of 3.3.1.10 is met. Then, with
the input signal still attenuated 37 1 dB, and with the logical zero still
applied to J2-f, apply the digital type-A logical zero to to J2-i and again
fire the unit at the same target Verify that the requirement of 3.3.1.10.
is met.
4.6.12 Events counter test. Observe the performance of the
events counter during a laser firing to determine compliance with 3.3.1.11.
4.6.13 AGC inhibit test. Apply 37 1 dB attenuation at the receiver
aperture input. Apply the digital type-B signals of table I to J1-j and J1-k
with the waveforms shown on figure 7. Measure the input at J2-j to
determine compliance with 3.3.1.12. Remove the type-B signals from
J-lj and J1 -k, and again measure the output at J2-j to determine
compliance with 3.3.1.12.
4.6.14 Reticle illumination test. Adjust the reticle light
control voltage (item 2.8, table I) to obtain normal illumination.
Visually examine the reticle etchings against a darkened background
to determine compliance with 3.3.1.13. Vary the reticle light
control voltage and observe the intensity of illumination to
determine compliance with 3.3.1.13.
4.6.15 A trigger threshold test. Set the energy output
level of the unit to 18.0 3.O millijoules. Verify that the require-
ment of 3.3.1.14 is met.
4.6.16 Diopter adjustment test.
4.6.16.1 Diopter adjustment torque (+75 15F and +125F) test.*
This test shall be conducted with standard torque measuring equipment
provided with appropriate adapters to accommodate the assembly
under test to determine compliance with 3.3.1.15.1. Utilizing an
adapte affixed to the diopter knob,measure the running torque to
determine compliance with 3.3.1.15.1.
*Dioptcr adjustment torque tests performed at the component level may be
utilized to satisfy this test and the test of 4.6.16.2.
