Nuoptix Stereo Optical Recording System, Owner'S Manual

Page: 9 / 38

ELECTRONICS may be recorded by switching the input select switch from
INPUT to AUX. The XMOD test signals may be used to verify crossmodulation
distortion cancellation on the print or for recording standard crossmodulation
distortion tests. The PINK TONE test signal is a digitally generated signal which
appears as a spectrally flat signal on a 1/3 octave spectrum analyzer but can be
read from a recording as short as 3 frames to verify *system and print frequency
response. Following the recording, the mode switch may be switched to the
REVERSE position for density check or to the E TEST position which alternates
reverse bias and bias line. Following the recording the mode switch should be
returned to the SETUP position to protect the light valve.
CAUTION: OPERATION OF THE RECORDING SYSTEM WITH CONSTANT
FREQUENCY ABOVE 8kHz AND 80% MAY CAUSE PERMANENT DAMAGE
TO THE LIGHT VALVE.
