Tektronix PSM3000, PSM4000, and PSM5000 Series are compact USB Power Sensors/Meters that deliver fast, accurate RF and Microwave Power measurements. The Sensors/Meters feature the industry's fastest measurement speed (2000 readings per second) and cover a wide dynamic range of -60 dBm to +20 dBm, and frequencies ranging from 10 MHz up to 26.5 GHz. Tektronix RF Microwave Power Sensors/Meters come with Windows-based power meter application software, providing a complete test solution that eliminates the need for a separate meter mainframe. Using a patented technique to ensure stability and calibration over the entire temperature range, the need for frequent sensor zeroing and meter reference calibration is eliminated. PSM3000 Series provides true average power measurements; PSM4000 Series delivers average power (CW) measurements plus pulse and peak power measurements; PSM5000 Series provides the same measurements as PSM4000, with the addition of pulse profiling.
