Spectrum analyser delivers versatility for field engineers

Wireless test engineers out in the field can now access frequency coverage up to 54GHz with Anritsu’s Field Master Pro MS2090A RF handheld spectrum analyser launched today (February 26) at Mobile World Congress in Barcelona (February 25-28). Real-time spectrum analysis bandwidth is pushed up to 100MHz.

The instrument comes in a durable housing, with a 10in. capacitive touchscreen which exceeds impact protection standards and will come as relief to Anritsu’s service department which deals with screens damaged by dropped tools on a regular basis.

The analyser caters for all tastes. Seven models are available with frequency coverage of 9 kHz to 9/14/20/26.5/32/44 and 54 GHz. The family features best-in-class performance, such as Displayed Average Noise Level (DANL) of <-160 dBm and Third Order Intercept (TOI) of typically +20 dBm, for more accurate spectrum clearing, radio alignment, and harmonic and distortion measurements.

The 100 MHz modulation bandwidth, along with best-in-class phase noise of typically -110 dBc/Hz @ 100 kHz offset, permit highly accurate modulation measurements on digital systems to be made.

A ±0.5 dB (typical) amplitude accuracy ensures highly confident measurements of transmitter power and spurious.

The Field Master Pro MS2090A’s 100MHz bandwidth allows for real-time spectrum analysis, while its low noise floor complemented by a Spectrogram display make it easy for field technicians and engineers to conduct RF spectrum monitoring and locate intermittent or interfering signals.

As many as six traces can be individually configured to display clear/write, max or min hold, average, and more.

It can be integrated with the NEONMA8100A Signal Mapper to create a 3D in-building or wide area outdoor coverage mapping solution, as well.

The instrument is suited for general spectrum analysis applications. Integrated Channel Power and Occupied Bandwidth (OBW) measurements simplify the characterization of common radio transmissions.

A built-in Adjacent Channel Power measurement simplifies the measurement of out-of-band transmitter emissions as required to speed conformance testing.

Anritsu leverages its field instrument leadership to design a durable housing that’s ready for the rigours of testing outside the lab. A rubber over-mould protects connectors from drops, and a large 10in. colour touchscreen exceeds Impact Protection IK08 standards to withstand field use.

The screen has 1280 x 800 resolution and high-contrast colour schemes that allows results to be seen in any condition, including nighttime and in bright sunlight.

A touchscreen simplifies operations. Users can swipe and scan across the frequency range, or pinch and zoom to quickly view signals of interest.

Menus have been carefully planned and tested to follow industry standard touchscreen design guidelines.
