Benchtop features and bandwidth in a handheld spectrum analyzer!

The MS2721B 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, WiMAX, and wireless medical patient monitoring systems. The MS2721B is ideal for AM and FM broadcast proofing because the wide dynamic range and low phase noise make NRSC measurements on analog and IBOC signals easy with no need for an external carrier notch filter.  The MS2721B 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.

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 MS2721B spectrum analyzer has low phase noise of -100 dBc/Hz @ 10 kHz offsets, best in its class typical DANL of -163 dBm 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. It automatically sets the fastes possible sweep speed consistant with accuracte measurement results.

Store over 1000 test set-ups and measurements internally. The use of Compact Flash memory modules or USB Flash Drives up to 32 GB allows an unlimited number of traces and setups to be stored. Measurements may be stored directly to the compact flash module or the USB Flash drive. A 512 MB module will hold over 20,000 Spectrum Analyzer measurements. Remote programming using the Ethernet 10/100 Base-T connection is provided using SCPI programming. The Ethernet connection gives 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.

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

  • Handheld, battery-operated design
  • RBWs: 1 Hz to 3 MHz in 1-3 sequence, VBWs: 1 Hz to 3 MHz in 1-3 sequence
  • Normal, Max hold, Min hold, user settable trace averaging
  • 6 Markers plus 6 delta markers or choose one marker with 6 delta markers 
  • Multi-segmented upper and lower limit lines

Convenient operating procedures, high sensitivity, excellent repeatability and exceptional performance enable the MS2721B to simplify measurements on wireless systems for easy verification of system compliance. Typical applications include:

  • 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 MS2721B an ideal choice for the challenge of rugged environments
  • Broadcast measurement AM & FM analog and IBOC proofing measurements
  • Interference mitigation in many diverse situations including wireless patient telemetry in hospitals
  • Digital Video testing in DVB-T/H and ISDB-T formats
