Description

The PDH receiver Monitor levels are 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.
