Anritsu Company has introduced the MS2070A, the latest member of its Field Master™family of handheld spectrum analyzers. Built on a field-proven durable platform, the Field Master MS2070A provides necessary features and performance up to 3 GHz at an economical price. It is designed to conduct RF measurements in a variety of general-purpose field, lab and manufacturing environments.
With a dynamic range of > 105 dB at 2.4 GHz and 20 MHz analysis bandwidth, the MS2070A can capture and measure digitally-modulated signals used in commercial and military applications. Typical displayed average noise level with a built-in optional preamplifier of -167 dBm, coupled with a Third Order Intercept of +11 dBm and typical level accuracy of ±0.5 dB enables a full range of signals to be captured by the handheld spectrum analyzer. The MS2070A is designed to allow engineers to 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.
PERFORMANCE IN HARSH ENVIRONMENTS
Leveraging the existing Field Master platform, the MS2070A is well-suited for the harsh environments associated with field applications. A ruggedized battery-powered instrument, the MS2070A has IP52 environmental protection when it is contained in the supplied soft carry case to withstand dust and water. It also has a 5 W RF damage level to protect the instrument from accidental overpowering.
Ruggedness extends to its IK08-rated display that can withstand accidental knocks or drops of tools on the screen. The 10-in. display has 1280 × 800 resolution and its multi-touch screen presents measurement results in large and clear formats. Common functions are always accessible and side menus collapse to maximize graphical results, as well.
Further complementing its field use, the MS2070A is compact and lightweight. It measures 290 × 212 × 96 mm and weighs 3.8 kg, making it easy to transport the handheld analyzer to remote sites.
WIDE SET OF STANDARD FEATURES
The Field Master MS2070A provides many of the key features typically found in higher-priced instruments. It has zero span to display TDD and pulsed signals with a narrow resolution bandwidth (RBW) of 10 Hz to 5 MHz for accurate measurements of power over time. Spectrograms are also standard, allowing spectrum versus time displays that result in accurate detection of intermittent interferers.
As many as six traces can be set simultaneously with different detectors. Averaging can be applied to each, as well. Up to 12 markers are provided, so signals of interest can be highlighted and monitored for variation over time, relative to themselves and other signals. Alerts for new interfering or lost signals are generated automatically. Additionally, upper/lower, envelope and alarm limits are standard on the MS2070A to optimize long-term spectrum monitoring. Several “smart” measurements are also standard in the Field Master MS2070A. The handheld spectrum analyzer can conduct occupied bandwidth (OBW), channel power and adjacent channel power using just a few keystrokes.
REMOTE CONTROL AND CONNECTIVITY
Ethernet and USBTMC interfaces are standard on the Field Master MS2070A, providing flexible options for remote instrument control. The USBTMC interface allows the Field Master MS2070A to be controlled from a smartphone, tablet or PC with an Android operating system. A Wi-Fi 802.11b/g/a/n interface is available as an option to connect to wireless routers for common applications, including downloading digital maps and automatic software updates.
FOR FIELD AND BENCH USE
The Field Master MS2070A can be used for a variety of field applications. It can conduct basic transmitter testing, including determining signal presence, modulation bandwidth and symmetry and harmonics and spurious. Interference hunting to determine if unwanted signals are in a spectrum can also be performed with the handheld spectrum analyzer. Cellular network operators can also configure the MS2070A with a PIM stick for PIM hunting.
In lab and manufacturing environments in which portability and space are at a premium, the MS2070A can be used for standard RF measurements. It has the performance to conduct EMC pre-compliance testing of new PCBs during electronic circuit development. The spectrum analyzer can also serve as a general-purpose instrument for routine measurements during product design and test.
FIELD MASTER FAMILY
The MS2070A is the base model in the Field Master family. A mid-range model, the MS2080A, operates up to 4 GHz and integrates a spectrum analyzer, real-time spectrum analyzer (RTSA), cable and antenna analyzer and LTE/5G base station tester into a single battery-powered instrument. The high-end Field Master Pro MS2090A RTSA delivers continuous frequency coverage from 9 kHz to 54 GHz. It can also be configured with optional 110 MHz RTSA, IQ streaming and pulse analysis.
