50 MHz, 32-Channel PXI Digital Waveform Instrument—The PXI-6541 is a digital waveform generator and analyzer for interfacing with 32 single-ended digital pins. The PXI-6541 can sample digital waveforms at up to 50 MHz and interface with common transistor-to-transistor logic (TTL) voltage levels. The PXI-6541 also features advanced synchronization capabilities for building integrated mixed-signal test systems.
