Product Overview

The Anritsu MS2721A is the first fully-functional handheld spectrum analyzer designed to conduct highly accurate analysis on the new wave of wireless LAN and cellular signals, including 802.11a, 3G, ultra-wideband, WiMAX, and wireless medical patient monitoring systems. The MS2721A is ideal for AM and FM broadcast proofing because the wide dynamic range, makes NRSC measurements on analog or IBOC signals easy with no need for an external carrier notch filter.  The MS2721A is a small and easy to use portable spectrum analyzer with unprecedented measurement capability for applications up to 7.1 GHz. Weighing in at less than 7 pounds, it is equally at home on the engineering bench and in the field. Spectrum Master model MS2721A is an entirely new instrument for deploying, maintaining and troubleshooting wireless base stations and Wi-Fi (802.11a, b and g) systems.  Options add spectrogram, signal strength and RSSI.  There is an option to add user definable channel scanner option that is excellent for interference mitigation work in complicated RF environments. Several smart measurements are built into the MS2721A, including channel power, adjacent channel power ratio, Carrier to Interference ratio (C/I), and field strength. In addition, an AM/FM/SSB demodulator is included. Demodulated signals can be monitored using the internal speaker or by using a universal 2.5 mm 3-wire headset, such as used with many cellular telephones. The MS2721A spectrum analyzer has low phase noise of -100 dBc/Hz @ 10 kHz offsets, best in its class typical DANL of -153 dBm at 1 GHz, resolution bandwidth (RBW) range of 10 Hz to 3 MHz and video bandwidth (VBW) range of 1 Hz to 3 MHz. It also has the fastest sweep speeds of any spectrum analyzer in its class. The use of external Compact Flash memory modules up to 512 MB allows an unlimited number of traces and setups to be stored. Measurements may be stored directly to the compact flash module.  A 512 MB module will hold over 20,000 measurements. Remote programming using the Ethernet 10/100 Base-T connection is provided using SCPI programming. Both the Ethernet connection and the USB 2.0 connection give the user flexibility in remotely operating the instrument using Anritsu's remote access software, shipped with the product. Measurements and setups may be uploaded and downloaded using either the Ethernet or the USB connection.
