Reverse sweep is the same process only backwards, just optimize the node, then get a reference at the node with the wavetek field unit, then compare each amp-le with that reference and maintain the flatness of the reverse bandwidth using eq's,(this process makes all the actives run the same db's as the node) If you have cable modems or digital box data in the reverse spectrum already , use the guard band feature in the transmitter so it does not inject sweep points in the used data area's,, also +7 reverse telemetry is the number wanted at the node by adjusting the telemetry level in the transmitter in the head end
node optimization is basically injecting a carrier at the node and receiving a certain level in the headend
remember telemetry is the freq channel that the transmitter and field units communicate with
and Sweep points are injected between channels, always check that the sweep points are 5 db under your loudest channel (usually digital channels run 10 db colder than the analogs do)
