REVERSE SWEEP (Optional Purchase Required)
In Reverse Sweep, the DSAM transmits a range of sweep points upstream to the headend, and communicates with the headend transceiver over a reverse telemetry frequency. The headend transceiver controls the sweep points transmitted from DSAM with a reverse sweep plan configured in the transceiver and transmitted by telemetry on a forward frequency.

Reverse sweep uses sweep carriers transmitted from DSAM to the headend transceiver. The transceiver measures the sweep carriers and transmits the results over forward telemetry back to DSAM which calculates return path frequency response by comparing the results to the local measurement of the same carriers.

Refer to Measure Sweep Overview for an explanation of system sweep and the functioning of the sweep components.
