The MS2721A is a fully-functional handheld spectrum analyzer designed to conduct analysis on the new wave of wireless signals, including 802.11a, 3G, ultra-wideband, and WiMAX. The next-generation of Anritsu's popular Spectrum Master family, the MS2721A is a small and easy to use handheld spectrum analyzer with unprecedented measurement capability for applications up to 7.1 GHz that weighs in at less than 7 pounds. 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. Several one button 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 spectrum analyzer has phase noise of at -100 dBc/Hz @ 10 kHz offsets, 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. The use of external Compact Flash memory modules allows an unlimited number of traces and setups to be stored. Ethernet 10/100 Base T and USB 2.0 connections are provided to give the user flexibility in remotely controlling the instrument as well as in uploading and downloading traces and settings.
