FSK-SGLS Generator - FSK001 - GDP Space Systems - Telemetry Systems, Synchronizers, BERTS, Demodulaters, Modulators, Receivers, Frame Synchronizers, decommutator, Simulators

The FSK001 is a high performance FSK/AM/PM Modulator which produces SGLS (Space Ground Link Subsystem) compatible subcarriers. Selectable modulations include: FSK, FSK/AM, FSK/PM, FSK/AM/ PM. The module accepts SGLS dibit encoded serial data and clock, or ternary (1,0,S) data and clock inputs for Ternary FSK modulation. External serial data (AUX) or the internal PRN data generator are selectable sources used for binary FSK modulation. The FSK output level is adjustable from -30 to +20 dBm (into 75 Ohms). A fixed-level FSK Test Point output is also provided. The PRN data and coherent clock are also provided as outputs.

Features

Accepts Tertiary or Dibit Encoded Data
Generates Selectable SGLS Tri-Tone Signals
Low Phase Noise Digital Frequency Synthesizer
Selectable Modulations
Internal PRN Data Generator
VME Bus Compatible 6U Single Height Module

A digital frequency synthesizer is utilized to produce SGLS tritone signal frequencies. Each FSK tone is tunable to 5MHz. (All FSK001 signals are generated by Direct Digital Synthesis (DDS) and are accurate to 100 ppm (1 ppm optional). ) Any combination of the ternary frequencies are selectable for the binary FSK tone pair. The FSK signals can be amplitude modulated with a triangular wave, supporting fixed command symbol rates of 1 Ksps, 2 Ksps, 5 Ksps or 10 Ksps. If AM is turned OFF, the FSK modulation data rate is tunable to 100 Kbps. The resultant FSK or FSK/AM signal can either be output or used to Phase Modulate a sub-carrier.

All user selectable parameters are controlled via the VME bus interface.

The FSK001 provides support for testing and up-link commanding in the SGLS environment. The internal PRN data generator is a data source for ranging applications as well as performing bit error testing on the data link. In addition to supporting VME system installations, the FSK001 is part of the GDP Space Systems family of Modular Subcarrier System (MSS) components. The MSS provides high performance, multi-channel Phase Shift Keyed (PSK), Frequency Shift Keyed (FSK), Space Ground Link System (SGLS) and Digital Baseband signal generation.
