System Description
The Anritsu MS271xB Economy Microwave Spectrum Analyzer Family (MS2717B, MS2718B, and MS2719B) delivers
affordable spectrum analysis with exceptional performance, advanced capabilities, and modern W-CDMA and WiMAX
signal analysis.
The MS2717B with Tracking Generator, MS2718B, MS2719B Economy Microwave Spectrum Analyzers, and PSN50 High Accuracy Power Sensor
Introduction
Engineers in R&D and manufacturing need advanced tools for spectrum analysis of wireless components in the critical
physical layer of modern communication systems. For best value and overall satisfaction, these general purpose tools
must deliver performance, capabilities, and the ability to lower the cost of testing. Anritsu’s new MS271xB Economy
Microwave Spectrum Analyzers offer superior performance and advanced capabilities. Take a closer look and we think you
will agree that the MS271xB family redefines the economy class by delivering superior spectrum analyzer performance
at a surprisingly affordable price.
Covering the 9 kHz to 7.1, 13 and 20 GHz ranges, the MS271xB family easily handles most RF and microwave spectrum
nalyzer needs. The hallmark of the MS271xB family is the phase noise performance: typical –110 dBc/Hz SSB phase
a
noise at 10 kHz offsets up to 7.1 GHz (MS2717B) which easily measures most wireless local oscillators and synthesizers.
The superior dynamic range of 100 dB means fast and precise testing of wireless components that require exceptional
linearity. The wide 10 MHz demodulation bandwidth supports optional W-CDMA/HSDPA, W-CDMA, and WiMAX
measurements. Best of all, the MS271xB family is ergonomically designed so controls are easy-to-learn and easy-to-use
for improving productivity in manufacturing, R&D, and general purpose testing.
Standard Measurements
• ACPR: Measures power levels in the channels
immediately above and below the center channel.
• Occupied Bandwidth: Measures 99% to 1% power
channel of a spectrum.
•
Channel Power: Measures the total power in a
specified bandwidth.
C/I: Measures carrier to interference ratio.
•
