Description
The signal from the HP 37718A/19A SDH/SONET Transmitter is applied
to the SDH/SONET 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.
Equipment Required
Procedure
1 Recall the HP 37718A/19A DEFAULT SETTINGS as shown on page 3-
