Electronic systems produced by ECTEC have been developed as instrumentation for supporting realistic battlefield testing of contemporary C4 - ISR systems and C-IED systems. The instrumentation systems have application as over-the-air emitters and as measurement systems for real-time stimulated response measurement applications.
This is a multi-channel rf-emission generator used to produce realistic battlefield rf signal environments to test modern U.S. Army reconnaissance systems. Phantom provides the capability to produce over 10,000 real signals per hour with an environment consisting of a mix of tactical, commercial, hostile, and friendly communications signals. The system is packaged in a 30” x 14” x 8” enclosure (L x W x H).

This product was developed as advanced range instrumentation for ATEC. Gator I provides a small (5”x 5” x 7”), remotely controllable, battery-operated rf-transceiver system for selective degradation of tactical vehicles communications in the field training environment..
Figure 2 Gator Selective Channel Impairment Module
The system operates across the frequency range from 100 KHz to 3000 MHz. The receiver is designed to selectively receive single or multiple control tones and use the measured amplitude to adjust the signal generator signal output amplitude. The system is battery powered. The network interface is 1000BaseT with an AES-II encrypted Ethernet link. The operating temperature range is from 0 to 55 degrees C.
This product was developed to meet a requirement for stimulating and measuring the response of CREW systems with extremely high fidelity in the time and frequency domains. CrossBolt is a multi-octave, high dynamic range signal generator and receiver system and leverages the performance from our synthesizers and modulators to meet specific measurement requirements associated with force protection systems.

The system incorporates a high performance receiver section, an exciter section for signal generation, and a customized Spectral Processor in a highly ruggedized enclosure. The overall dimensions of the unit are 6” x 6” x 9”. The unit weighs 9.5 lbs. It covers the 100 KHz to 10 GHz frequency range (expandable to 18 GHz) and has a variety of scan modes that can be implemented. The network interface is 1000BaseT with an AES-II encrypted Ethernet link. The operating temperature range is from 10 to 150 degrees F.
Sample Signal Images
The following (Figures 4 – 10) are instrumentation screen pictures of several signal types produced by our modulator circuitry embedded in the Phantom II, Gator, and CrossBolt products. These include Vector Signal Analyzer images, Spectrum Analyzer images, and custom time-domain display images. All of the modulation results shown were produced with real “message” data
