The Tektronix PSM5320 is a USB-connected RF and microwave power sensor for accurate measurements across 50 MHz to 18 GHz. This standalone instrument eliminates the need for a separate mainframe, delivering portable power sensing and metering in a compact form factor. The PSM5320 measures average power, pulsed signals, and statistical distributions without external calibration, connecting directly to a host PC via USB 2.0 for control and data logging.
