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. Options add spectrogram, signal strength and RSSI. A user definable channel scanner option that is excellent for interference mitigation work in complicated RF environments.
Several smart 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 MS2721A spectrum analyzer has low phase noise of -100 dBc/Hz @ 10 kHz offsets, best in its class 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. It also has the fastest sweep speeds of any spectrum analyzer in its class.
The use of external Compact Flash memory modules allows an unlimited number of traces and setups to be stored. Remote programming using the Ethernet 10/100 Base-T connection is provided using SCPI programming. Both the Ethernet connection and the USB 2.0 connection give 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.

Applications:
Convenient operating procedures, high sensitivity, excellent repeatability and exceptional performance enable the MS2721A 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 MS2721A an ideal choice for the challenge of rugged environments
- Broadcast measurement AM & FM analog and IBOC proofing measurements
Options:
- Option 25 - Interference Analysis - provides a spectrogram display, signal strength with audible tone and RSSI (received signal strength indication indication)
- Option 27 - Channel Scanner - adds the capability to select up to 20 channels or signals to monitor. (Great for interference mitigation)
