NI PXIE-6555 is NI’s 200 MHz, 24-channel PXI Express digital waveform instrument with onboard PPMU. NI identifies the module as a digital waveform generator and analyzer intended for interfacing, characterization, and DC parametric testing. The PXIe-6555 specifications further define it as a 24-channel, PPMU-enabled instrument using single-ended, ground-referenced generation, acquisition, and PPMU channels. https://www.ni.com/en/shop/hardware/digital-instruments/model-pxie-6555 https://www.ni.com/docs/en-US/bundle/pxie-6555-specs/page/specs.html
The module supports up to 200 MHz operation. NI specifies an onboard/sample clock frequency range of 800 Hz to 200 MHz, with hardware compare also rated to 200 MHz. Onboard memory is listed as 8 Mbit per channel for acquisition and 8 Mbit per channel for generation, with 32 MBytes total for each function. Programmable acquisition threshold range is -2 V to 7 V, while generation voltage ranges are software-selectable from -2 V to 6 V by default or -1 V to 7 V. https://www.ni.com/en/shop/hardware/digital-instruments/model-pxie-6555 https://www.ni.com/docs/en-US/bundle/pxie-6555-specs/page/specs.html
For parametric test functions, NI specifies PPMU force voltage ranges of -2 V to 6 V by default or -1 V to 7 V, with PPMU measure voltage range from -2 V to 7 V. Timing features include sample clock source options from the onboard clock, CLK IN (SMA), PXIe_DStarA, and STROBE for acquisition only. Relative delay adjustment is specified to ±5 ns with 3.125 ps resolution. Hardware compare capability includes an error FIFO depth of 4,094 and support for 255 unique enable states. https://www.ni.com/docs/en-US/bundle/pxie-6555-specs/page/specs.html
