8300 FST
Forward SpeedSweep Transmitter
The 8300 FST Forward Speed Sweep Transmitter is an essential part of the system for comprehensive sweep capability in the 860 DSP Field Analyzer family
- The instrument is rack-mounted in the headend, and generates a sweep that steps around system carriers to avoid interference, filling in vacant spectrum areas for a complete view of the network frequency response
- 860 DSP (with FS-1 option) receives the sweep and based on the measured sweep and system carrier levels plots the frequency response
- The response is compared to a stored reference to provide a difference display
- With the goal of the network design being unity gain from amplifier output to amplifier output, the ideal response will be as flat as possible
- The sweep test provides a measure of the RF transmission characteristics of the network between the transmitter and the receiver, and is used as a day-to-day maintenance tool for the RF portion of the HFC network
