TIMTER™ Transmitters

Quasonix TIMTER™ transmitter

Third-Generation Workhorse

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.

Product Configurations

  • L/S/C band

Baseband Interface

  • TTL or TIA/RS-422 (RS-422)

Other Highlights

  • Outputs from 10 mW to 25 W and optional variable power – all while drawing less current than the competition

  1. Hello, I am a reliability Engineer and I am looking for a parts list for the Transmitter. Can you provide me with the part list and electrical schematic displaying the parts associated with the Multi-Mode Telemetry Transmitter. If there is already a FMECA available for this component, please also provide that information. My Email can be found below.

    Thanks

    • All our transmitters are COTS products, and design details like parts lists and schematics are highly proprietary. We cannot provide those.
      If you have specific questions about the transmitter line, we should first start with a part number. We do have MTBF calculations for some models, and we could share those. Or we can quote doing a new analysis.
