ETL Systems TLT-D-C2C1-1002 C-Band Test Loop Translator 5.725–6.725 to 3.4–4.4 GHz

ETL Systems TLT-D-C2C1-1002 C-Band Test Loop Translator 5.725–6.725 to 3.4–4.4 GHz

The ETL Systems TLT-D-C2C1-1002-S5S5 is a C-band-to-C-band test loop translator module for satellite communications test systems. It converts signals from 5.725–6.725 GHz to 3.4–4.4 GHz without spectral inversion.

The synthesised local oscillator provides 1 kHz frequency steps and a ±250 MHz control range. Input and output frequency settings are user controllable. Instantaneous bandwidth is 1 GHz at the centre LO setting and decreases when the LO is offset from centre.

Attenuation is adjustable from 0 to 60 dB in 0.25 dB steps, with a specified step tolerance of ±0.20 dB over the operating band. Conversion gain is 0 ±3 dB at the 0 dB attenuation setting. A mute function provides at least 80 dB suppression.

The hot-swappable module occupies eight slots in a compatible GENUS 1U chassis. The datasheet specifies one translator module maximum per chassis. Local touchscreen and remote Ethernet monitoring and control are provided through the compatible chassis platform.

This listing covers one TLT-D-C2C1-1002-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 one translator module maximum per chassis. Instantaneous bandwidth decreases when the LO is offset from its centre setting. The reference stability temperature range is not a complete module operating-temperature specification. Confirm the chassis configuration and required frequency plan when requesting a quotation.
