When plugged into Compact PCI slot, 4-channel Model CPCI-520 uses D/A converters to generate 2.5, 5, and 10 V outputs with 12-bit resolution, plus ±10 Vdc and 4-20 mA with 16-bit resolution. All channels update when triggered by onboard or user-supplied clock signal. Separate logic input causes maskable interrupt to PCI bus. Timebase has 50 µsec to 3.3 sec range.
