Quantum line · Beacon tracking receiver
A step-track beacon receiver for the 19-inch rack, with 1 to 4 switched L-band inputs, reporting beacon level, lock and health over SNMPv2c or SNMPv3.
Overview
Quantum runs the same receiver and measurement software as the Polaris DTR: the same tuner, detection bandwidths, lock criteria and health metrics. It leaves out monopulse and the analog ACU interface, and puts everything on the network instead.
Up to four RF inputs are switched inside the unit, so one receiver can watch beacons from different bands, polarizations or antennas. Beacon level, C/N, lock and faults are read over SNMPv2c or SNMPv3 by the station's M&C system.
Features
Order 1 to 4 RF inputs and select any of them remotely; each can be named by band and polarization and stored with up to four beacons.
FFT detection from 1 kHz to 1 MHz bandwidth, with gain calibration to your reference point and automatic frequency control for slow drift.
SNMPv2c for the NMS you already run, or SNMPv3 with SHA-256 authentication, AES-128 privacy and separate monitor and control users; tune, select inputs and read every metric.
Lock, C/N, C/N₀, drift, interference detection, low-signal alarm and a fault log, readable on the network.
One receiver application serves both lines, so Quantum gets the same field-deployable updates.
19 in rack, 2U as standard. A DIN-rail mount (-DM) is available as an option for cabinets and distributed sites.
