General Safety Precautions

Please observe the following safety precautions at all times when using Mini-Circuits

smart power sensors.

Note the maximum input power rating in the datasheet and the conditions

specified for it. Exceeding these values may damage the power sensor.

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 data-

processing 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 with plug and play functionality making them perfect for field or remote

use.

1.6

Service and Calibration

The only user-performed service possible for the PWR models is external cleaning of the case

and connectors as needed. Do not use any detergents or spray cleaning solutions to clean the

PWR unit. To clean the connectors, use an alcohol solution, and to clean the PWR case, a soft,

damp cloth. The recommended calibration cycle for Mini-Circuits PWR series smart power

sensors is once a year. Calibration service is available from Mini-Circuits. For details; see

Ordering, Pricing & Availability Information link from individual model pages on the website.
