Measurements
Operating manual HVC 32 a. HVC 42 - Version 01-2021Apage 16
Measurements
A bidirectional test socket [9] with approx. 20 dB decoupling atten-
uation is located at the input. Using the test socket you can:
Estimate the input level for the forward range
Determine the output level for the return range
Feed in return signals behind the return path amplifier in the
upstream direction
Feed in forward signals in the downstream direction
At the output, there is adirectionally coupled test socket [8] with
20 dB decoupling attenuation. You can use it to:
Feed in the return signal to set the return path level
Determine the output level for the forward range
NOTE: After configuring the amplifier and completing the
measurements, it is strongly recommended to terminate both
test sockets with FUR 75 terminating resistors to ensure
operation in compliance with the standards.
