specified for it. Exceeding these values may damage the power sensor.
2. Do not exceed the operational safe power levels for extended periods of time.
1.5 Introduction
Traditionally, when you wanted to measure signal power from electronic components or circuit
boards, you’d have to connect them to a bulky and expensive bench-top power meter. Not
anymore. Mini-Circuits PWR power sensors offer a whole new approach, using a quick, simple,
USB or Ethernet connection to turn your Windows® PC or laptop into an RF/Microwave power
meter.
The PWR series offers a low-cost replacement solution for conventional RF/Microwave power
meters, but goes even further by adding portability, easy data storage, advanced dataprocessing capabilities, and remote operation via Ethernet. Unlike most conventional bench-top
instruments, they’re self-calibrating and compensate automatically for temperature. They’re
quick and easy to use, whether you’re in the field or helping someone complete a remote test
installation over the phone.
