L-3 Telemetry-East has designed and developed a wide variety of aircraft flight test products ranging from simple encoder/transmitter systems to large scale master/remote Data Acquisition Systems (DAS). These systems have been used by virtually every large aircraft contractor on commercial programs, and by aerospace contractors and government agencies on critical military programs.
Applications
Aircraft Flight Test
Missile and Launch Vehicle Test
L-3 Telemetry-East has provided, and continues to provide, products and systems to the major U.S. and foreign aerospace companies and government agencies involved in missile and launch vehicle testing. Missile programs such as Tomahawk, Stinger, Trident, and THAAD, to name a few, use L-3 Telemetry-East transmitters, encoders, signal conditioning, and data acquisition systems.
Precision Munitions Test
L-3 Telemetry-East has developed a unique, modular product consisting of a PCM encoder and S-Band transmitter used in projectile test applications. These units can be modified to accommodate virtually any requirement and can be physically repackaged to meet a wide variety of form factors, depending on installation needs.
Telemetry Ground Equipment
L-3 Telemetry-East manufactures a wide variety of telemetry ground equipment, including receivers, complete computer-controlled ground stations, and a wide variety of support products servicing the range telemetry, space data, signal intelligence, and satellite Telemetry, Tracking and Control (TT&C) communities. These products include configurations suitable for rack mount, modules for VME chassis and PC applications, and complete turnkey installations.

The Model 3362 is a full function 20 Mbps tunable dual-channel QPSK PCM bit synchronizer in a 3-rack-unit chassis. It is ideally suited for reconstructing a noisy input PCM data stream and providing a clean PCM signal with a coherent clock. The unit can be operated as a single- or dual-channel bit synchronizer. By providing dual channels, I and Q outputs from a QPSK receiver demodulator may be processed and recombined into a single output.
Each channel of the Model 3362 is tunable over the bit rate range of 10 bps to 20 Mbps for NRZ codes and up to 10 Mbps for BiØ codes. The standard NRZ-L/M/S, BiØ-L/M/S, DBiØ-M/S, DM-M/S, MDM-M/S codes are accepted from one of three input sources. The 3362 produces an output data stream with a bit error rate within 1 dB of theory. The 3362 excels in BER performance, offering enhanced sync maintenance and acquisition capabilities. It maintains effective
synchronization down to an Eb/No of -3 dB and acquisition time is less than 20 transitions in noise. The loop bandwidth can be set anywhere in the range from 0.01% to 1.60% without losing phase lock.
