Broadcast transmitter analysis. Pre-compliance testing for electromagnetic compatibility. Passive intermodulation hunting. If phrases like these make your eyes light up — well, for one thing, you’re in the right place reading Electronics360 content. But it might also come as welcome news to hear that the Anritsu Company has just launched a hand-held spectrum analyzer that packages these features and more at what the company says is an economical price.
Designed for standard swept spectrum analysis up to 3 GHz, the Field Master MS2070A draws upon the performance and durability of the rest of the company’s Field Master family, providing many capabilities typically found in higher-priced instruments. According to a press release, the new device features sweep speeds of up to 32 GHz/s in common low noise configurations. A number of “smart” measurements, including occupied bandwidth (OBW), channel power and adjacent channel power (ACP), are standard.
And the standard features don’t end there. A zero span displays time division duplexing (TDD) and pulsed signals with narrow resolution bandwidth (RBW) of 10 Hz to 5 MHz for accurate measurements of power over time. Spectrograms allow accurate detection of intermittent interferers. As many as six traces can be set simultaneously with different detectors, and averaging can be applied to each. With up to 12 markers provided, signals of interest can be highlighted and monitored for variance over time, relative to themselves and to other signals. Alerts for new interfering or lost signals are generated automatically. For long-term spectrum monitoring applications, the MS2070A provides upper/lower, envelope, and alarm limits.
One might be tempted to think that Anritsu needed to skimp on durability to bring these features together in a low-cost package, but the MS2070A is a ruggedized battery-powered instrument featuring a durable, IK08-rated 10 inch display with 1,280 x 800 resolution. IP52 environmental protection is provided when the instrument is contained in the supplied soft carry case, and a 5 watt RF input damage level provides protection from accidental overpower.
With a dynamic range of greater than 105 dB at 2.4 GHz , typical displayed average noise level (DANL) with a built-in optional preamplifier of -167 dBm, Third Order Intercept (TOI) of +11 dBm, and typical level accuracy of ±0.5 dB, the MS2070A allows a full range of signals to be analyzed.
