The Anritsu MS2721B is a high performance handheld Spectrum Master spectrum analyzer covering 9 kHz to 7.1 GHz. It is built to give the wireless professional the performance needed for demanding measurements in harsh RF and physical environments, combining a portable, battery-powered handheld form factor with a full spectrum analysis feature set.
Anritsu positions the Spectrum Master for spectrum monitoring, broadcast proofing, interference analysis, RF and microwave measurements, regulatory compliance, and Wi-Fi and wireless network measurements. Across these tasks it is intended to make fast and reliable measurements in the field.
ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Pre-owned units are inspected and functionally verified in-house by our technicians before they ship, while new units ship factory-sealed exactly as received from the manufacturer.

Important: Maximum continuous input is +30 dBm (≥10 dB input attenuation), ±50 VDC; the input damage level is greater than +43 dBm.
Important: High Accuracy Power Meter operation (Option 0019) requires an external USB Power Sensor, which is not included with the base unit and must be ordered separately (PSN50, MA24105A, MA24106A, MA24108A, MA24118A, or MA24126A — see the respective sensor datasheets for complete ordering information).
Important: Most signal-analyzer measurement and demodulation options require Option 0009 (I/Q Demodulation Hardware); the W-CDMA/HSDPA, cdmaOne/CDMA2000 1X, and CDMA2000 1xEV-DO Over-the-Air options additionally require Option 0031 (GPS Receiver).
Important: Recommended calibration cycle is 12 months.
