Pocket-sized USB spectrum analyzers address emerging mmWave
Anritsu Company has expanded its Spectrum Master MS2760A ultraportable spectrum analyzer series with extended broadband frequency coverage from 9 kHz – 170 GHz, as well as introduced a new series of higher sensitivity models – the Spectrum Master MS2762A – with coverage from 6 GHz to 170 GHz for the most demanding sensitivity requirements.

This family of tablet-driven, pocket-sized analysers combines flexibility and portability with best-in-class dynamic range, allowing design and production engineers to perform basic spectrum measurements, such as channel power, occupied bandwidth, adjacent channel power, and harmonic measurements, on CW signals up to 170 GHz. The Spectrum Master MS276xA family of ultraportable spectrum analyzers provides a full suite of cost-efficient verification tools for a growing number of emerging millimeter-wave (mmWave) applications.

With the addition of two new Spectrum Master MS2760A models and eight introductory Spectrum Master MS2762A instruments, the Spectrum Master MS276xA family of ultraportable spectrum analyzers are direct-connect instruments that offer superior dynamic range of typically 108 dB at 70 GHz.

The Spectrum Master MS2762A high sensitivity models have typical DANL as low as -141 dBm from 6 GHz to 90 GHz, covering numerous bands starting from midway through the C band through the E band. Above 90 GHz, typical DANL performance remains superior at -136 dBm to 110 GHz; -129 dBm between 110 and 145 GHz; and -122 dBm between 145 and 170 GHz. This performance allows engineers to see more low-level signals, making the spectrum analyzers well suited for numerous applications, including radio astronomy in the D band.

The lower noise floor allows the Spectrum Master MS276xA family to conduct accurate spectrum mask testing of mmWave, point-to-point radios during production. Amplitude accuracy is typically ±1 dB, which provides engineers with greater measurement confidence and improves overall product performance. With a sweep speed of less than 24 seconds (typical, processor speed dependent) over the full 6 GHz to 170 GHz frequency range, the new models shorten test times.
