RF power meters, also known as RF power sensors, are used in both signal analysis and EMC radiated immunity testing. They generally focus on measuring over the frequency range of 50 MHz to 40 GHz and vary from benchtop systems to small modules to expand the frequency of a system already on hand.
In choosing a system, finding one that matches the user’s RF signals and modulation types is essential. ATEC offers affordable RF power meter rental and calibration from top manufacturers such as Keysight, Boonton, Rohde & Schwarz, and PMM.
What Is An RF Power Meter?
These devices measure power caused by radio frequencies (RF). They consist of two pieces: the meter, which displays the power reading, and the sensor head, which contains the power-sensing component that connects to both the meter and the device under test.
This equipment works in conjunction with a spectrum analyzer and other devices to perform power measurement and analysis. Test engineers select a sensor based on its frequency range, dynamic range, and modulation format. They come in a variety of modulations allowing them to measure the characteristics of CW (continuous wave), average, peak, and pulse waveforms.
Power specifications are vital to the design of RF components and are reflected directly in the performance of nearly all devices that generate microwaves. The growing number of devices that support wideband data transmission require these sensors to determine average power, peak-to-average ratios, and peak power or time-gated profiles.
Choosing An RF Power Meter Rental
Since there are multiple ways of measuring RF power, different equipment exists to be used for RF power measurement:
- In-line power meters measure power flowing along a feed-line.
- Absorptive power meters absorb the power they measure and convert it into a signal.
- Spectrum analyzers measure power level on a particular frequency.
Choosing the right power meter rental is crucial in testing equipment as accurate RF signal detection is very important in any application.
