Description:

The MS2721A was 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 was replaced with model MS2721B.
