Description
The National Instruments (NI) PXI-4071 is a 7½-digit high-performance PXI (PCI Express Extensions for Instrumentation) digital multimeter (DMM) with an onboard 1.8 MS/s isolated digitizer. This means it combines the functionalities of two instruments in one:
- High-Resolution DMM: It can measure a wide range of electrical quantities with high accuracy and precision, including:
- Voltage: DC and AC voltage with ranges up to ±1000 VDC and 700 Vrms.
- Current: DC and AC current with ranges up to ±3 A.
- Resistance: Resistance measurements from 10 Ω to 5 GΩ.
- Frequency and period
- Diode testing
- High-Speed Digitizer: It can acquire and digitize DC-coupled waveforms at high sampling rates of up to 1.8 MS/s. This allows you to capture and analyze the rapid changes in voltage or current signals..
Key Features:
- Wide Measurement Range: The PXI-4071 offers a broad range for voltage, current, and resistance measurements, making it suitable for various applications.
