Dual Frequency Synthesizer - Model 543 - GDP Space Systems - Telemetry Systems, Synchronizers, BERTS, Demodulaters, Modulators, Receivers, Frame Synchronizers, decommutator, Simulators

The GDP Space Systems Model 543 Dual Frequency Synthesizer addresses the need for a laboratory source of programmable clocks.

Using Direct Digital Synthesis techniques, the unit offers substantial features compared to phase-locked loop architectures. Finer frequency resolution over the entire bandwidth, low phase noise, less complexity (i.e., easier maintenance), faster switching/setting time and phase-continuous frequency changes are inherent to the design.

Features

10 bps to 20 Mbps Range
Two Independent Synthesizers
0.1 Hz Frequency Resolution
1X and 2X Outputs Available
Based on DDS Technology
Digital Outputs: TTL, RS422, RS232
0° Accumulated Phase Shift for Integer Submultiple Frequencies
Int/Ext 5 MHz Reference (Optional 10 MHz)

Keypad and VF Display for Local Control
Phase Continuous Frequency Changes
IEEE-488 or RS232 Remote Control
Non Volatile RAM for 10 Setups
Compact, 3.5" high

Two independent synthesizers provide greater flexibility in system test. While both channels use the same reference, the frequencies are set separately, This means multiple and sub-multiple rates will not "walk" past each other. Bit stuffing techniques can be closely examined.

The keyboard and bright, high contrast vacuum fluorescent display allows users to directly enter the required frequencies. The unit stores 10 frequency combinations in non-volatile RAM for quick recall. 1X and 2X clock outputs are available for 1X rates up to 10 Mbps. The 1X output alone is available up to 20 Mbps.

All operating controls and indicators are located on the Front Panel. All signal and Power connections are located on the Rear Panel.
