9-21. SINAD Detection. The SINAD of a signal on the DVM FROM RNG SW line is determined by taking the
ratio of the input to the output signal power on the 1 kHz Notch Filter. Signal power is determined by Rectifier
and Filter circuits whose outputs are DC levels proportional to the input signal levels. The DC levels, SINAD IN
and SINAD OUT are digitized and input to the processor where the SINAD is calculated.
9-22. Module Control. Processor control of the Scope/DVM Control module is via the AF ADD BUS 0-3, the
AF DATA BUS 0-3, and the AF BUS EN 1 signal lines. The four address bits are decoded by the Address
Decode to determine which Control Latch the fours bits of data will be latched. The latching process is
synchronized by the enable line. Control latches in addition to those necessary for controlling the module
provide control for the Scope Amplifier module and part of the RF Input module.
