Anritsu Co. announces the availability of real-time spectrum analysis (RTSA) tools for its Field Master Pro™ MS2090A handheld spectrum analyzer that can accurately measure the amplitude of a single spectrum event as short as 2 µs and detect a single event as minimal as 5 ns. Its ability to more accurately detect intermittent interfering signals provides distinct advantages in a number of aerospace/defense, satellite systems and radar applications, as well as 5G and mobile backhaul.

The Field Master Pro MS2090A RTSA provides a continuous stream of FFT measurements over a 110 MHz analysis bandwidth which enables a 2.055 µs probability of intercept (POI), allowing it to more accurately detect signals that are short in duration or hop in frequency, as compared to standard swept-tuned spectrum analyzers. Density and spectrogram displays are available to more easily identify and track intermittent or pulsed signals, making the MS2090A extremely well suited for spectrum analysis, spectrum clearing, and interference hunting.

Seven models are available with frequency coverage of 9 kHz to 9/14/20/26.5/32/44 and 54 GHz. Other best-in-class performance features of the MS2090A include Displayed Average Noise Level (DANL) of < -160 dBm and Third Order Intercept (TOI) of typically +20 dBm. The 100 MHz modulation bandwidth, along with phase noise of typically -110 dBc/Hz at 100 kHz offset, permit highly accurate modulation measurements on digital systems to be made. A ±0.5 dB (typical) amplitude accuracy ensures high confidence in measurements of transmitter power and spurious.

Durable Design 

Anritsu leverages its field instrument leadership to design a durable housing that’s ready for the rigors of testing outside the lab. A large 10-inch color touchscreen exceeds Impact Protection IK08 standards to withstand field use. The screen has 1280 x 800 resolution and high-contrast color schemes that allows results to be seen in any condition, including nighttime and in bright sunlight.

The touchscreen simplifies operations, allowing users to 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.
