Fourth-Generation Powerhouse
Quasonix digital multi-mode telemetry transmitters are the benchmark of the industry, providing unparalleled performance and value, in small, robust, power-efficient packages. The TIMTER™ transmitter, now in its third generation and smaller than ever at 4.1 cubic inches, offers the most versatility of any transmitter in the industry, with advanced capabilities like L/S/C frequency tuning and output power up to 25 Watts.
ARTM Modulations
Quasonix transmitters offer three different modulations of increasing spectral efficiency – PCM/FM, SOQPSK-TG, and Multi-h CPM – also known as ARTM Tiers 0, I, and II, at standard bit rates from 0.1 to 28 Mbps (0.05 to 14 Mbps for PCM/FM). Options (HR/LR) are available to extend the upper limit to a maximum of 46 Mbps (23 Mbps for PCM/FM) and the lower limit to a minimum of 50 kbps (25 kbps for PCM/FM). With bandwidth at a growing premium in flight test telemetry, you can take advantage of 2 to 2.5 times the data capacity of the legacy PCM/FM waveform with SOQPSK-TG and Multi-h CPM.
