Wide Dynamic Range USB Smart Power Sensor, 75Ω, -30 dBm to +20 dBm, 100 kHz to 2500 MHz


Mini-Circuits’ PWR-2.5GHS-75 is a low-cost compact sensor-head that turns any PC with a USB port into an average power meter for CW (continuous waveform) signals. The sensor has a 50 dB input dynamic range allowing measurement of RF powers down to -30 dBm, over 100 kHZ to 2500 MHz.
The USB HID interface is “plug & play” compatible, meaning no driver installation is required.
