ANRITSU has released the MS2721A, a handheld spectrum analyser designed for wireless signals including 802.11a, 3G, ultra-wideband and WiMAX.

It weighs less than 2.9kg and covers the 100kHz to 7.1 GHz frequency. It has a number of one-button measurements, including field strength, channel power, occupied bandwidth, adjacent channel power ratio (ACPR) and carrier to interference ratio (C/I).

The spectrum analyser has phase noise of -100dBc/Hz at 10 kHz offset, DANL of -152dBm at 2.2GHz typically, and a resolution bandwidth (RBW) range of 10Hz to 3MHz. It has the fastest sweep speeds of any spectrum analyser in its class.

It has a 65dB step attenuator, input protection to 20W, true RMS detection and offers over three hours of battery life. It has a daylight-viewable 21cm TFT colour display, external and internal compact flash slots and Ethernet 10/100 and USB 2.0 ports.

It can be remotely operated using a LAN connection with a known IP address. The Remote Tools software looks just like the front panel of the MS2721A and controls the instrument from a Windows XP or 2000 PC.

It can withstand the harsh environments associated with field use and has an operating temperature range of -10°C to 55°C.
