The NI 1424 comes with 16 MB of onboard high-speed synchronous dynamic RAM (SDRAM). You can purchase additional SO-DIMM memory upgrades from National Instruments. SO-DIMM upgrades are available in 64 MB and 128 MB densities. The NI 1424 can also use the onboard RAM as a first-in first-out (FIFO) buffer so that in some instances, the NI 1424 can capture images larger than the amount of RAM on the device. -
Page 15: High-Speed Timing
Chapter 2 Hardware Overview High-Speed Timing The high-speed timing circuitry on the NI 1424, built from high-speed counters, allows you to specify or generate precise, real-time control signals. You can map the output of this circuitry to a trigger line to provide accurate pulses and pulse trains. -
