ETL Systems TLT-D-C3L1-1005 C-Band to L-Band Test Loop Translator 5.725–6.725 GHz to 950–1950 MHz

ETL Systems TLT-D-C3L1-1005 C-Band to L-Band Test Loop Translator 5.725–6.725 GHz to 950–1950 MHz

The ETL Systems TLT-D-C3L1-1005-S5S5 is a C-band-to-L-band test loop translator module for satellite communications test systems. It converts signals from 5.725–6.725 GHz to 950–1950 MHz without spectral inversion.

The synthesised local oscillator is controllable from 3925–5625 MHz in 1 kHz steps. Input and output frequency settings are user controllable. Instantaneous bandwidth is specified as 1 GHz at the centre LO setting.

Attenuation is adjustable from 0 to 30 dB in 0.25 dB steps, with a specified step tolerance of ±0.20 dB over the operating band. Conversion gain is −20 ±3 dB at the 0 dB attenuation setting. A mute function provides at least 80 dB suppression.

The hot-swappable module occupies four slots in a compatible GENUS 1U chassis. The manufacturer specifies a maximum of three modules per chassis. Local touchscreen and remote monitoring and control are provided through the compatible chassis platform.

This listing covers one TLT-D-C3L1-1005-S5S5 translator module. The GENUS chassis, external reference source, RF cables, and other accessories are sold separately unless included in the quoted configuration. Touchscreen, Ethernet, SNMP, web interface, and redundant power features depend on the selected chassis configuration.

The manufacturer specifies a maximum of three translator modules per chassis. The 1 GHz instantaneous bandwidth rating applies at the centre LO setting; confirm bandwidth for the required frequency plan. The reference stability temperature range is not a complete module operating-temperature specification. Confirm RF connector details and the chassis/reference configuration when requesting a quotation.
