The MS2090A Field Master Pro pushes the boundaries of what’s possible in a field spectrum analyzer. With up to 54 GHz of frequency coverage, it's engineered to address emerging challenges in 5G, satcom, radar, backhaul, and interference hunting. The analyzer offers RTSA capabilities with bandwidths up to 150 MHz, critical for capturing bursty or intermittent signals in real time.

It excels in spectrum clearing, transmitter alignment, and spurious/harmonic testing thanks to its superior DANL (–164 dBm) and TOI (+20 dBm). Additionally, its ±0.5 dB typical amplitude accuracy and –110 dBc/Hz phase noise at 1 GHz ensure confidence in critical modulation and RF quality measurements.

Designed for harsh outdoor use, the MS2090A also enables IQ capture for offline 5G frame analysis, channel power and OBW testing, and interference geolocation, making it the ultimate all-in-one analyzer for engineers in the field.
