A test loop translator (TLT) is a type of radio frequency converter or heterodyne, used to translate between uplink and downlink segments (generally in the same band), to allow for "loop-back" testing and calibration of the ground segment without the need to interface with the satellite.[1][2] TLTs generally contain a fixed or preset local oscillator and a preset gain, though the LO and gain may be adjustable in some models.[1] Most models have a negative gain (i.e., a loss), with -15 dB being the most common.[1]
