The ATLT- S100 from Advantech Wireless Technologies is a Test Loop Translator that converts an S-band RF input frequency of 2025-2120 MHz to an RF output frequency of 2199-2303 MHz. This test loop translator has a high stability internal reference of 10 MHz and an output impedance of 50 Ohms. It has a maximum conversion gain of -35 dB and a gain adjustment of 40 dB. The test loop translator has a spurious of 45 dBc (In-band) and a phase noise of up to -115 dBc (1 MHz). It has an output VSWR of 1.5:1 and a return loss of 18 dB. The test loop translator supports a user-friendly front panel or the RS485 remote interface for full set-up and fault monitoring. It requires a supply voltage of 90-265 VAC and has a power consumption of 20 W. The ATLT-S100 measures 482.6 x 44.5 x 508 mm and is designed for testing satellite communications links.
