PCI-5421 is an arbitrary waveform generator from NI (National Instruments Corporation).

The PCI-5421 can generate any user-defined waveforms and standard functions, including sine, square, triangular, and sawtooth waves. This arbitrary waveform generator can generate signals from -6 V to +6 V and uses direct digital synthesis (DDS) to accurately generate arbitrary waveforms up to 4.4 MS/s.

PCIe, short for Peripheral Component Interconnect Express, is a high-speed serial computer extension bus standard.

PCIe is a high-speed serial point-to-point dual-channel high-bandwidth transmission. Connected devices allocate exclusive channel bandwidth but do not share bus bandwidth. It supports active power management, error reporting, end-to-end reliable transmission, hot swap, and quality of service.

PCI-5421 is NI's arbitrary waveform generator. The PCI-5421 device is available in three versions, with three options for on-board memory sizes. Part number 778692-01 has 8MB of onboard memory, part number 778692-02 has 32MB of onboard memory, and part number 778692-03 has 256 MB of onboard memory. The device is used to generate arbitrary waveforms defined by the user. The PCI-5421 device can also generate standard sine, ramp, triangle, and square signals. To accurately generate the waveform, PCI-5421 uses direct digital frequency synthesis (DSS). The device can also be used for streaming data and advanced synchronization.

The PCI-5421 comes with an analog output channel that has an SMB(jack) connector. The DAC resolution of the output channel is 16 bits. It is DC coupled. Channels at the output end of the PCI-5421 device can combine waveforms in similar paths. This means that the device supports waveform summation. Therefore, the output terminals of different modules can be connected. The PCI-5421 waveform generator device has a maximum bandwidth of 43 MHz. The device has a 7-pole elliptic filter.

The PCI-5421 waveform generator device has two two-way channels. Users can program these. These channels have SMB(jack) type connectors. These channels range in frequency from DC to 105 MHz. As input, these channels are used as trigger channels. The maximum input overload is -2 to +7V voltage. These channels can also be used as the output of an event generator.
