The Anritsu MS2721A Spectrum Master is an ultra-portable, battery-powered handheld spectrum analyzer delivering high performance in a field-ready form factor. It provides continuous frequency coverage from 100 kHz to 7.1 GHz and combines high sensitivity, wide dynamic range, and a suite of built-in measurement routines in an instrument weighing about six pounds fully loaded, including its Li-Ion battery.
The MS2721A is built for both field and lab work. In the field, it supports interference detection, spectrum monitoring, wireless system planning, RF and microwave signal measurements, cellular signal measurements, and WiFi and WiFi5 installation and testing. Its wide frequency coverage suits installing and maintaining 802.11a, 802.11b, and 802.11g wireless networks, while the built-in AM/FM/SSB demodulator helps identify interfering signals. In the lab, independently adjustable resolution bandwidth and video bandwidth, a user-settable input attenuator, and a switchable preamplifier give the flexibility needed for demanding measurements.
ValueTronics stocks and holds its own test-and-measurement inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house by qualified technicians before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding inventory directly means faster fulfillment and accountable condition reporting on the instruments we sell.
