Anritsu Corporation has launched the Power Master MA24507A, an ultraportable, millimetre wave (mmWave) power analyser that enables simple, numeric, frequency-based measurement of radio frequency (RF) power ranging from 9 kHz to 70 GHz. Power measurement is difficult at mmWave frequencies because as the signal frequency increases, attenuation due to the air or cabling grows. To this end, the Power Master MA24507A’s ultraportable size enables users to place it directly at the signal source, including on wafer measurements. Moreover, when system losses are unavoidable, the MA24507A can make measurements as low as 90 dBm at 70 GHz, making it a superior alternative to large benchtop instruments that are unwieldy in the field. The Power Master analyser is USB-powered, has power measures of approximately 6x3x1 inches and weighs less than 15 oz, slightly bigger than a smartphone. It is a small and lightweight device that can be eas­ily used to make measurements on antenna towers with an extension pole to measure small cell signals from the ground.

The Power Master MA24507A enables frequency selective power measurements, which helps users to differentiate between intended signals and unintended signals. It measures signals ran­ging from 1 kHz and covering the entire frequency band. The analyser can also zero in on a signal of interest in harsh environments, including those with unintended signals that can affect power readings. This enables measurements such as channel power and adjacent channel power to be made, while avoiding spurs and harmonics. It does not require reference calibration, unlike many other power measurement instruments. Further, the power analyser can constantly stay connected to a test system, eliminating the need to disconnect and reconnect it between test procedures. It can also be used when the accuracy of a traditional power meter is not necessary, when unintended signals are present, or low-level power measurements are required. Besides, the Power Master MA24507A can be controlled remotely through the USB interface or through Anritsu’s PowerXpert data analysis and control software.

According to the company, it is a frequency selectable RF power analyser that leverages Anritsu’s patented Shockline technology to address the growing number of test requirements in mmWave applications, including the testing of 802.11ad, wireless HD and e-band products at every stage of the product life cycle. Moreover, the ultraportable product category allows customers to achieve greater benefits in terms of portability, performance and measurement accuracy.
