The receiver is designed for use in MSOs, independent CATV and high-end SMATV systems. The receiver and VideoCipher module are in a common 19-inch-wide rack-mountable chassis, 1.75 inches high. The receiver uses a 950 to 1450 MHz RF input and a 70 MHz intermediate frequency (IF) output. The VideoCipher Module can be easily slid into or removed from the chassis from the rear panel. The module's address label is visible through a slot on this panel.
Satellite transponder (channel) or frequency selection is by a front-panel thumbwheel switch. Either C-Band or Ku-Band transponder frequencies may be selected directly by the thumbdial switch. Alternatively, C-Band standard channels 1.24 may be selected, eliminating the step of setting a frequency. When a frequency is selected directly, video inversion is performed automatically.
The VideoCipher right, left, and mono audio output levels are adjustable from the front panel with a single AUDIO LJR/MONO control. A detent on the control represents an internally adjustable 0 dBm output level (± 1 dB). The bypass mono audio signal is provided by the #1 audio subcarrier demodulator. An internal adjustment provides setup and calibration. The output level is adjusted for 0 dBm when tuned to a standard C-Band 6.8 MHz mono subcarrier (150 kHz peak deviation). The Video/Composite output level for bypass and VideoCipher descrambling are both adjustable from the front panel VIDEO LEVEL potentiometer. The detent position of this potentiometer is a calibrated 1 V p-p output with a standard VideoCipher scrambled video signal (10.75 MHz video deviation at C-Band and 9.2 MHz at Ku-Band). A front panel VIDEO/OSD test point allows output level monitoring when terminated into a 75 ohm load. The 70 MHz IF output is a 50 ohm impedance and a level of approximately -30 dBm throughout the AGC range. The #1 audio can be turned off so that in the bypass mode, the operator can defeat the bridging of the #1 audio across the R/L & Mono outputs.
