AtlanTecRF Launches LTT for Satcom RF Testing

AtlanTecRF has launched a plug-in 6U Loop Test Translator (LTT) for satcom RF testing. The traditional configuration for loop test translators used in off-satellite set up, calibration, alignment and quality monitoring of ground based equipment in satcom terminals is the 19” x 1U rack mount chassis. In other applications such packaging does not deliver optimum equipment densities or ease of operation. In such situations AtlanTecRF's plug-in 6U Module comes into its own, bringing ATE stacking principles to the satcom RF test world.
