Wavetek 3HRV
The 3HRV Reverse Sweep Receiver is a headend rack mounted unit
that handles the reverse sweep job for up to 10 different technicians
on the same cluster of nodes.
The addition of the 3HRV to the Wavetek Sweep System takes the
responsibility of the reverse sweep away from the 3ST. This serves to
speed up the reverse sweep rate. In addition, the 3HRV sends out
reverse ingress/noise information with every update of its forward
telemetry, so reverse telemetry need not be received in order to check
the reverse ingress condition.
