Overview

The Field Master MS2070A is the latest version of Anritsu’s handheld spectrum analyzers. Built on a field-proven durable platform, the Field Master MS2070A provides a comprehensive set of features with excellent performance up to 3 GHz. MS2070A is designed to conduct RF measurements in a variety of general-purpose field and lab environments.

With dynamic range of >105 dB at 2.4 GHz, the MS2070A can capture and measure HF, VHF and UHF signals common in commercial and military applications. Typical DANL with a built-in optional preamplifier of -167dBm, coupled with a Third Order Intercept (TOI) of +11 dBm and typical level accuracy of ±0.5 dB enable a full range of signals to be captured by the handheld spectrum analyzer.

The MS2070A is designed so engineers can conduct standard swept spectrum analysis measurements simply and accurately up to 3 GHz. It features sweep speeds of up to 32 GHz/s in common low noise configurations.

Applications

Broadcast transmitter analysis

A comprehensive range of transmitter measurements – including: AM/FM modulation quality measurements, harmonic, spurious, occupied bandwidth, channel power, and adjacent channel power – ensures conformity to regulatory requirements.

Interference hunting and spectrum clearing

Fast sweep speeds a low distortion front-end combine to quickly identify interfering signals. A special interference finder option adds AM/FM demodulation with audio output plus interfering source triangulation on a digital map to pinpoint and identify the location and source of interference.

EMC pre-compliance

To prevent interference with other products, all consumer and industrial products need to be tested to confirm compliance with EMI/EMC regulations. Final compliance testing is typically done at a certified test house. To maximize the confidence of the product passing first time, pre compliance testing is ideal for identifying points of failure.

PIM Hunting

With widespread use of rooftop sites for location of cellular base stations, Passive Intermodulation has become a major source of interference in base station receivers. Metallic objects on the rooftop including common items such as air conditioning units, guard rails and fasting bolts can act as generators of RF intermodulation products when in the line of site of transmitters. The 2000-1884-R PIM Hunter accessory used with MS2070A’s fast sweep speed pinpoints the origin of PIM on a rooftop.

75 Ω Cable TV testing

Cable TV distribution in residential and commercial locations uses 75 ohm coax cable. The 12N50-75B 50 to 75 ohm adaptor connects directly to the MS2070A RF port with a calibrated offset to display the spectrum of all channels on a cable TV run. Quickly identify missing channels or interference between channels due to overmodulation in the standard spectrum analyzer view.
