Model RM-6300
RF Exciter & Test Signal Simulator
Wideband Integrated Multi-Mission Solution

Applications

  • Integrated Programmable Waveform Generator, Modulator, Noise Generator, Upconverter and BER Test System
  • RF Link and Range Setup, Testing and Operation
  • SatCom Science, and Military Missions
  • Supports IRIG 106 applications
  • SGLS and STDN Ground Stations
  • Mobile Tracking and Data Systems
  • Payload and Product Integration, Simulation and Testing

The RM-6300 RF Exciter & Test Signal Simulator combines a state-of-the-art high data rate digital wideband waveform modulator with a high performance radio frequency (RF) upconverter to produce transmission-ready signals in the Baseband, Upper L-, Lower L-, Range S-, Satellite Uplink S-, Satellite Downlink S-, and Range C1- (4 GHz) and Extended C2- (5 GHz) frequency bands. Alternately, C1- and C2- can be provided as P1- and P2-Bands for sites using CIF.

An advanced, digital implementation provides for the small form and fit while fully satisfying applications requiring ruggedized packaging, minimum power consumption, and high spectral purity. The design supports a multitude of complex digital formats for Satellite and ARTM Range use.

Data generation, coding, and modulation can be driven from a variety of external digital inputs or via internal pattern and waveform generation sources. Dual data processing paths are included to allow creation of independent I and Q streams.

The practical design of the RM-6300 Exciter supports link test and verification applications. A single RM-6300 can replace a BERT, waveform generator, vector modulator, upconverter, amplifier, noise source, attenuators, power meter, spectrum analyzer and a frequency converter. Combining these capabilities in one small, simple-to-use unit allows quick and accurate setup and testing without in-depth system knowledge.

An optional second, independently tunable modulated RF output may be used effectively with dual-polarized systems. Output power levels are adjustable for fine control and fade profiling.

Configuration Profiles can be stored with user-defined link names and recalled with a single command, simplifying fast and accurate configuration changes .

Configurable front panel BNC connectors provide operators with ready access to internal operating signals. The RM-6300 can also optionally support a station clock input for external frequency reference.

The RM-6300 includes support for user-configurable Doppler simulation and satellite acquisition automation functions.

The firmware-intensive implementation of the RM-6300 readily accommodates custom features and signal processing tasks. Using the latest generation digital signal processing techniques allows upgrades via firmware changes, even for previously fielded systems.

The RM-6300 RF Exciter is available in a standard 2U 19 inch rack mountable chassis.
