MS2781A signal analyser

Anritsu's Signature (model MS2781A) signal analyser provides the spectrum and signal analysis tools engineers require to design and manufacture advanced RF and microwave communications systems, including WLAN, 3G and 4G.

The analyser has been developed with an advanced architecture that provides digital modulation analysis over the 100 Hz to 8 GHz frequency range. In addition, the architecture provides an optional 30 MHz resolution bandwidth for capturing, measuring and analysing wide modulation bandwidth signals.

The architecture also provides an open Windows environment allowing popular simulation and analysis tools to be easily integrated into the analyser.

The analyser delivers high-end performance in both spectrum analysis or vector signal analysis capability, with no trade-offs between either mode. Utilising a 9.5 to 17.5 GHz synthesised first local oscilloscope (LO) and 9.5 GHz IF, this fundamental mixing approach allows the entire 100 Hz to 8 GHz frequency range to be measured in one sweep, without band switching or preselection.

As a result of this design approach, the device offers improved sensitivity, intermodulation distortion (TOI) and better dynamic range. It has TOI of +23 dBm, DANL of <-147 dBm and typical amplitude accuracy of <0.65 dB over the entire frequency range.

For digital modulation analysis, the unit has optional measurements for error vector magnitude (EVM), carrier leakage and I/Q imbalance, all without a separate computer and post processing. The signal analyser has >80 dB WCDMA ACPR (typical) and 2% EVM. A 30 MHz IF bandwidth option is also available.
