The RF I/O block handles high-power transmitter signals and low-level receiver testing. It features a heavy-duty RF attenuator pad capable of handling up to 125 watts of continuous transmitter power on the "RF In/Out" port. A separate, highly sensitive "Antenna" port is available for off-the-air monitoring. Receiver Block (Analyzer)
