Description

The signal from the HP 37717C PDH Transmitter is applied to the PDH Receiver
after attenuating by an amount equal to the selected Receiver Flat Loss plus the
specified Cable Loss. The Flat Loss is obtained by inserting a number of 50 , fixed
attenuators in series with a 75/50
Matching Pad at the other end. The loss of the two Matching Pads is included in the
overall attenuation equation. The Cable Loss is supplied by inserting the correct
Cable Simulators for each bit rate in the attenuation path.
