The new RF measurement option includes a suite of measurements to quickly and accurately measure TD-SCDMA signals. A Channel Spectrum view displays the signals of a selected channel, channel power in dBm or watts, and occupied bandwidth. The left and right channel powers and occupied bandwidth are displayed, as well. The option also includes a power-versus-time screen that displays the power over one signal frame or can zoom into a slot selected by the user. When in the frame view, individual slot powers are also displayed.

Modulation quality of TD-SCDMA transmitters can now also be evaluated with the MS271xB. When integrated with the TD-SCDMA demodulator option, the MS271xB can display the power of the 16 codes of a demodulated TD-SCDMA signal. Code Domain Power and Code Domain Error of the codes are displayed as a bar graph on the MS271xB's screen.

Measurement accuracy is assured because the MS271xB has best-in-class 100 dB dynamic range and phase noise of -110 dBc/Hz at 10 kHz offset (typical, 800 MHz). A new software package takes advantage of the phase noise specification and is an excellent tool to ensure the performance of wireless broadband components and devices.

Anritsu has also enhanced the MS271xB series with a GPIB interface so the economy microwave spectrum analyzers can be easily integrated into legacy manufacturing test systems.

Covering the 9 kHz to 7.1, 13 and 20 GHz ranges, the MS271xB family meets most RF and microwave spectrum analyzer requirements. The excellent phase-noise performance enables the spectrum analyzers to measure most wireless local oscillators and synthesizers, while their superior dynamic range results in fast and precise testing of wireless components that require exceptional linearity. Designed with a 10-MHz demodulation bandwidth, the MS271xB family supports GSM, CDMA, W-CDMA, W-CDMA/HSDPA, EVDO and WiMAX measurements — in addition to TD-SCDMA.
