The new PXI-4071 FlexDMM allows engineers to measure from picoamps to kilovolts. Featuring a 7-1/2-digit (26-bit) digital multimeter and a 1.8 MS/s isolated digitizer, the PXI-4071 FlexDMM is built to provide voltage measurements from 䔮 nV to ۫,000 V and resistance measurements from 10 micro-ohms to 5 giga-ohms quickly and accurately. The device incorporates a solid-state current shunt configuration that provides eight dc current ranges, from 1 mA to 3 A, and six ac rms current ranges, from 100 mA to 3 A. This design is intended to provide the flexibility, resolution, functionality, and isolation required in applications such as fuel cell testing, leakage measurements, IV curve tracing, and data converter linearity testing. The FlexDMM offers dc reading rates of 7 S/s at 7-1/2 digits and a maximum dc reading rate of 10 kS/s at 4-1/2 digits. When operating in isolated digitizer mode, the device can acquire dc-coupled waveforms in all voltage and current ranges with a 1.8 Ms/s maximum sample rate. Thanks to the built-in isolation, engineers can measure differential waveforms up to 500 V common-mode voltage, such as fuel cell stack testing. By changing the digitizer sampling rate, engineers can vary the resolution of the digitizer from 10 to 23 bits. The FlexDMM also allows users to analyze transients, fly-back signals, and other aperiodic high-voltage ac waveforms for both time and frequency when in isolated digitizer mode. Engineers can increase the channel count of the FlexDMM system by integrating switch modules such as the PXI-2532 512-crosspoint high-density matrix. By incorporating switch modules and switch management software, engineers can measure thousands of channels with a single multimeter. Pricing begins at $2,495.
