Anritsu introduces the Signature (MS2781A), a signal analyzer with performance, capabilities, and simplicity that redefines the high-end signal analyzer market. Signature has been developed with an advanced architecture that provides an optional 30 MHz resolution bandwidth for capturing, measuring, and analyzing wide modulation bandwidth signals. The architecture also provides an open Windows environment — allowing simulation and analysis tools to be easily integrated into the analyzer. The MS2781A's architecture utilizes a 9.5 GHz to 17.5 GHz synthesized first local oscillator (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 bandswitching or preselection. Signature intermodulation distortion of +23 dBm, DANL of <– 147 dBm, and typical amplitude accuracy of < 0.65 dB over the entire frequency range. For digital modulation analysis, Signature, optionally, has measurements for error vector magnitude (EVM), carrier leakage, and I/Q imbalance, all without a separate computer and post processing. The signal analyzer has > 80 dB WCDMA ACPR (typical) and 2% EVM. A 30 MHz IF bandwidth option is also available. Users can easily design new or proprietary digital modulations by adding the MATLAB® Connectivity Option. The option allows live update viewing of MATLAB processed results with measurements. Signature also allows charting of data right on the instrument.
