The Keysight E1497A is a C-size, 1-slot VXI embedded controller built on PA-RISC technology for real-time instrument control, data acquisition, and automated measurement applications. Configurable with either a 64 MHz or 100 MHz PA 7100LC processor, it delivers 77.7/121.6 MIPS and 24.3/37.8 MFLOPS performance paired with ECC SIMM RAM scaling from 16 MB to 128 MB depending on configuration. The controller integrates a 1-MB dual-ported memory buffer for high-speed data acquisition and 256 KB external cache, supported by HP-UX 9.05 and later operating systems.
