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.
