ACT-5X Exciter User Manual Note: The "TSNR", "LID" and "UID" in Table 2 are the measurements of feedback signal quality. This feedback signal could be from a transmitter or the exciter/translator itself and its input range is -30 dBm to 0 dBm (Recommended range is -15 dBm to -5 dBm). These measurements are derived from the After-filter Feedback Signal connected to the rear port [RF_IN_A] BNC connector.
