With a frequency range of 100 kHz to 7.1 GHz, the MS2717A spectrum analyzer from Anritsu Co. (www.anritsu.com) also covers many wireless applications. Yet this analyzer has a different goal: to be an “economy” spectrum analyzer for the masses. The MS2717A costs less than $12,000. To take up less space on a workbench, it comes in a unique size: 242 X 372 X 339 mm. The MS2717A offers 3-dB resolution-bandwidth filters from 10 Hz to 3 MHz and video-bandwidth filters from 1 Hz to 3 MHz. The 8-MHz-wide instantaneous (demodulation) bandwidth supports several options that simplify WCDMA/HSDPA measurements. The instrument boasts frequency resolution of 1 Hz. Among its other features are a typical dynamic range of 100 dB and a third-order intercept point of +29 dBm. Typical phase noise is –110 dBc/Hz offset 10 kHz for carriers to 6 GHz.
