ELECTRICAL TESTS. This section tests the critical voltages on the power supplies and CCAs inside
the camera.
(1)
POWER SUPPLY TEST. Checks the voltages, noise and inhibit characteristics of the five
camera power supplies.
(2)
ALC/AGC TEST. Checks the ALC and AGC function on the analog CCA.
(3)
FDLS TEST. Checks the voltage and timing parameters of the seven signals accessible via the
FDLS function in the camera.
g. VIDEO TESTS. These tests check the camera output for proper video.
(1)
VIDEO AMPLITUDE SNR TEST. Measure the video amplitude and signal to noise ratios with
the video amplitude adjusted so that the ALC output is set to 2.40 and 1.00 volts.
(2)
CTF. Contrast transfer function test. Measure the black-to-white response (contrast) at certain
frequencies and directs the operator to focus the camera (if required) to achieve the optimum resolution.
h. IMAGE GEOMETRY TEST. These tests check the rotation and boresight of the camera and directs
the operator to adjust, if the parameters are out of tolerance.
(1)
IMAGE ROTATION TEST. Measures the image rotation and adjusts the rotation and boresight,
if the parameters are out of tolerance.
