This is a complete transceiver designed to transmit and receive the direct-sequence spread spectrum BPSK modulated digital data over the European (868 MHz) and American (902 to 928 MHz) frequency bands.
The device can decode DVB/DSS QPSK and BPSK signals at 1-45 Msps, turbo QPSK at 15-30 Msps and turbo 8-PSK signals from 15-30 Msps.
The T400TSS signal modulator supports virtually all popular commercial and Government telemetry (and command) signal waveforms including FM, PM, FSK, BPSK, QPSK, OQPSK (SQPSK), and SOQPSK (MIL-STD and TG).
The T400XR has a configurable software- defined receiver/modulator, and supports most of the popular demodulation and modulation schemes such as BPSK, QPSK, SQPSK, UQPSK, SOQPSK, and SQPN (spread spectrum) signals.

The T400MSP produces high-accuracy, multi-channel uplink/downlink signals using any combination of BPSK, QPSK, 8PSK, MSK, FSK, AM, FM, and CW modes.
The front panel keypad or RS-232 controls Arbitrary Waveform Generation, Pulse and Function Generation and other waveform modes, including Sweep, VCO, AM, FM, Phase Modulation, FSK, SSB, BPSK, DTMF Generate and Detect, Burst and Power Level Measurement.
