The Tektronix PSM4410 is a USB-connected power sensor for RF and microwave measurements from 50 MHz to 20 GHz. It delivers accurate average, peak, and pulsed power analysis with dynamic range from -60 dBm to +20 dBm and measurement uncertainty as low as 2.6%. Operating at up to 2000 readings per second with 500 µs nominal measurement speed, the sensor connects directly to a host PC via USB 2.0, eliminating the need for external meter mainframes.
