Mini-Circuits has released the PWR-6G+ which is a Multi Channel USB Power Sensor with a 50 dB dynamic range. The USB power sensor comes with power meter software that turns the PC/laptop into a power meter.
PWR-6G+ does not require any reference signal calibration and has a frequency range of 1–6 GHz, with 50 ohm impedance, typical vswr 1.1:1 and accuracy ±0.15 dB.
No external power source is required and it is easy to install and operate.
The PWR-6G+ can measured up to 10 channels in parallel and take measurements relative to previous results. With printable data and graphs available, this is a low-cost replacement solution for the conventional power meter.
