For supporting documentation, see Library.

The MS2723B handheld spectrum analyzer is designed to conduct highly accurate analysis on the new wave of wireless LAN and cellular signals, including 802.11a, 3G, ultra-wideband, and wireless medical patient monitoring systems, dynamic range of 101 dB is the best in its class.   The next generation of Anritsu's best selling Spectrum Master, the MS2723B is a small and easy to use portable spectrum analyzer with unprecedented measurement capability for applications up to 13 GHz. Weighing in at less than 8 pounds, it is equally at home on the engineering bench and in the field. It is ideally suited for measuring up to the fifth harmonic of 3G cellular phone base stations.

Quasi-peak detection is included along with CISPR resolution bandwidths.
Multilingual User Interface (English, Chinese, French, German, Japanese, Spanish, Korean, Italian)

Several smart measurements are built into the MS2723B,  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 MS2723B spectrum analyzer has low phase noise of -104 dBc/Hz typical at 1 GHz @ 10 kHz offset, best in its class typical DANL of -159 dBm at 1 GHz,  in a 1 Hz RBW resolution bandwidth (RBW) range of 1 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.


Convenient operating procedures, high sensitivity, excellent repeatability and exceptional performance enable the MS2723B to simplify measurements on wireless systems for easy verification of system compliance. Typical applications include:

  • Measurement of the 5th harmonic of 3G cellular base station signals
  • Transmitter Spectrum Analysis - occupied bandwidth, channel power, adjacent channel power ratio and modulation
  • Received Signal Analysis - location and identification of in-band interference and out-of-band spurious signals and spectral masks
  • Signal Strength Mapping - to determine the most suitable location for antennas, base stations and repeaters
  • Field analysis of 3G signals - fast sweep speed, field-swappable battery, smart measurements and daylight-viewable display make the MS2724B an ideal choice for the challenge of rugged environments
  • Broadcast measurement AM & FM analog and IBOC proofing measurements
