The National Instruments PCI-4070 is a 6½-digit FlexDMM with remarkable throughput rates, high precision, and stable measurement accuracy. This combination of speed and accuracy was previously available only with higher-resolution digital multimeters (DMMs) costing thousands of dollars more. Thanks to the National Instruments proprietary FlexDMM technology, the NI PCI-4070 DMM also provides a fully isolated, high-voltage digitizer capable of acquiring waveforms at sample rates up to 1.8 MS/s at ±300 V input. Using the analysis functions in National Instruments LabVIEW software, you can analyze these waveforms in both the time and frequency domains. Because of its superior speed, accuracy, and functionality, the PCI-4070 is ideal for use in automated tests on both the production floor and in R&D environments.

Add Switching with USB Switch Mainframes
When used in automated test systems, the PCI-4070 Digital Multimeter is frequently located behind multiplexer or matrix switches. You can easily add switching to your PCI-4070 with the 4 or 12-Slot USB Switch Mainframes. The USB Switch Mainframes are completely assembled chassis/controller combinations with available plug-in slots for any of the 50+ switch configurations offered as SCXI modules. Some of the available options include:

NI SCXI-1127 64-channel, 300 V multiplexer/matrix offers an excellent solution for switching thermocouples, RTDs, or other sensitive measurements to the PCI-4070.

NI SCXI-1175 196-channel, 100 V multiplexer provides maximum channel count for high-density multiplexer configurations up to 100 V or 1 A. In a 12-Slot USB Switch Mainframe, you can multiplex more than 2300 signals to the PCI-4070!

NI SCXI-1130 256-channel, 60 V reed multiplexer/matrix combines high-channel-count multiplexer/matrix configurations with high-speed reed relays (900 ch/s). Create up to a 4x768 1-wire matrix in a 12-Slot USB Switch Mainframe.
