Handheld spectrum analyzers deliver unprecedented performance up to 43 GHz

December 20, 2012 // By Jean-Pierre Joosting
Anritsu Company has introduced the Spectrum Master™ MS2720T series, which provides field technicians and engineers with performance that rivals a benchtop spectrum analyzer.

The MS2720T features a touchscreen, full-band tracking generators to 20 GHz, and best-in-class performance for dynamic range, DANL, phase noise, and sweep speed, providing unprecedented levels of spectrum monitoring, hidden signal detection, RF/microwave measurements, and testing of microwave backhauls and cellular signals.

Continuous frequency coverage from 9 kHz to 43 GHz is provided by the Spectrum Master MS2720T. It features an improved sweep mode that allows users to set resolution bandwidth from 30 kHz to 10 MHz with minimal effect on sweep speed. Because the sweep speed with a 30 kHz bandwidth is nearly the same as a 10 MHz RBW, sensitivity can be selected without the need for long sweep times. For maximum flexibility, sweep triggering can be set to free run or a single sweep. In zero span, sweeps can be free run, set to trigger when a signal meets or exceeds a designated power level, or it can be externally triggered. Spans can be set from 10 Hz to 9, 13, 20, 32, or 43 GHz, in addition to zero span.

The MS2720T has dynamic range of >106 dB in 1 Hz RBW, DANL of -163 dBm in 1 Hz RBW, and phase noise of -112 dBm at 10 kHz offset at 1 GHz. A burst detect sweep mode function allows emitters as short as 200 µs to be captured every time, allowing the MS2720T to detect bursty signals that can lead to finding intermittent or bursty emitters. A Burst Detect™ Sweep Mode increases sweep speed more than 1,000 times in a 15 MHz span.

A full-band tracking generator that covers 100 kHz to 9, 13, or 20 GHz is available. The tracking generator provides state-of-the-art features not available on competitive handheld analyzers, including 0.1 dB power step size, wide dynamic range up to 100 dB, and power output flatness of ±0.5 dB. The tracking generator includes a Continuous Wave (CW) generator for measuring fixed frequency components,
