The National Instruments PCI-6542 is a powerful Digital Waveform Device designed for a variety of high-performance applications. Available in two memory configurations, this device features part number 778989-02 which provides 16 Mbit of onboard memory, and part number 778989-03, which offers 64 Mbit. Leveraging advanced Synchronization and Memory Core (SMC) technology, the PCI-6542 enables efficient sharing of instructions and waveforms within its onboard memory. Users can customize parameters such as the maximum number of waveforms stored, the count of script instructions, and the number of samples available for waveform generation. The device includes the NI Script Editor for intuitive waveform task creation, which is accessible upon driver installation from the NI-HSDIO DVD. For circuit prototyping and Device Under Test (DUT) evaluation, the PCI-6542 can be utilized with the NI CB-2162, while the NI SMB-2163 breakout box provides coaxial SMB connectors for each channel, facilitating easy connectivity for testing and troubleshooting. Physically, the PCI-6542 measures 12.6 cm by 35.5 cm, weighs 14.5 oz (410 g), and operates within a temperature range of 0 °C to 45 °C, with a storage temperature flexibility of -20 °C to 70 °C. Care should be taken to avoid exposure to conditions outside these parameters, and any cleaning should be conducted using compressed air. The PCI-6542 requires a power supply of +3.3 VDC, +5 VDC, +12 VDC, and -12 VDC, with a total power dissipation of 15 W. A warranty of 2-3 years applies, and a user manual is available for download.
