The Keysight DSA91304A is a 13 GHz digital signal analyzer built for high-speed signal characterization across four analog channels. It captures waveforms at up to 40 GSa/s with 8-bit ADC resolution (>12 bits with averaging) and delivers rise times as fast as 32 ps (10-90%). The instrument combines deep memory—up to 1 Gpts per channel—with acquisition rates exceeding 400,000 waveforms per second in segment memory mode, enabling efficient capture of rare or intermittent events. With noise floors as low as 1.25 mVrms at 13 GHz (50 mV/div), it provides the signal fidelity required for telecommunications, aerospace, and R&D applications. A 12.1-inch color touchscreen display, removable SSD storage, and USB 2.0/LAN connectivity support intuitive operation and data management. Advanced jitter analysis via EZJIT+ and EZJIT Complete, combined with hardware-accelerated de-embedding for probe and fixture compensation, enables precise signal validation. Protocol triggering and decoding span I2C/SPI, USB 2.0, PCI Express, MIPI D-PHY, Ethernet, HDMI 1.4, DDR1/2/3/4, DisplayPort 1.2, and multiple automotive standards. Compliance test packages support USB 3.0, PCI Express Gen 2, SATA 6G, DDR4, HDMI 1.4, and Ethernet validation. Optional upgrades include GPIB interfacing, extended memory configurations, and software modules for serial data analysis, InfiniiSim waveform transformation, and MATLAB integration. The DSA91304A operates with InfiniiMax I/II probing systems rated 1 GHz to 13 GHz.
