PDH Receiver Monitor Levels (Special Option 808)
Specification
Description
Option 808 provides an equalized Monitor input. This is checked by attenuating the
synthesizer output level by an amount equivalent to the extra gain provided by the
Monitor Amplifier. The synthesizer is set to generate a sinewave at half the bit rate
which corresponds to a ternary all ones signal. The receiver should sync up with no
errors if PATTERN [ALL ONES] is selected.
Equipment Required
