NI PXI/PCI-5142 Specifications 14-Bit 100 MS/s Digitizer with Onboard Signal Processing This document lists the specifications for the NI PXI/PCI-5142 (NI 5142) high-speed digitizer. Unless otherwise noted, the following conditions were used for each specification: • • • All filter settings All impedance selections Sample clock set to 100 MS/s Typical values are used to define an average unit measured at ambient temperatures of 15 °C to 35 °C. Specifications are subject to change without notice. For the most recent NI 5142 specifications, visit ni.com/ manuals. To access NI 5142 documentation, navigate to Start»All Programs» National Instruments»NI-SCOPE»Documentation. Hot Surface If the NI 5142 has been in use, the device or the shield may exceed safe handling temperatures and may cause burns. Allow the NI 5142 to cool before touching the shield or removing the device from the chassis or PC. Refer to the Environment section for operating temperatures.
