NOTE The Rates available are dependent on the HP 37718A/19A option
Description
The signal from the HP 37718A/19A 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 from a 75Ω, attenuator kit. The Cable Loss is supplied by
inserting the correct Cable Simulators for each bit rate in the
attenuation path.
