NI PXI series PXI-4071 Module for Test Measurement & Automation Systems

The NI PXI-4071 is a high-performance, multifunctional 3U PXI module that offers the measurement capabilities of two commonly used test instruments, namely a high-resolution digital multimeter and a digitizer.

Here is a detailed introduction in English:

General Features

High Precision Measurement: As a digital multimeter, the PXI-4071 can accurately measure voltages in the range of ±10 nV to 1000 V, currents in the range of ±1 pA to 3 A, resistances from 10 μΩ to 5 GΩ, as well as frequencies/periods and diodes.

Waveform Acquisition: In the high-voltage isolated digitizer mode, the PXI-4071 can acquire DC waveforms in all voltage and current modes at a sampling rate of 1.8 MS/s.

Excellent Performance: With outstanding speed, accuracy, and functionality, the PXI-4071 is an ideal choice for automated testing in production and R&D environments. It can also be used in conjunction with PXI switches to form a multi-channel high-voltage data acquisition system.

Specific Functions

Digital Multimeter Functions

Voltage Measurement: It can measure voltages from ±10 nV to 1000 V DC (700 V AC) with high accuracy. For example, when measuring the voltage of a small electronic component, it can provide precise readings.

Current Measurement: The module can measure currents from ±1 pA to 3 A, covering a wide range of current values. This is useful in various electrical circuit testing scenarios.

Resistance Measurement: It is capable of measuring resistances from 10 μΩ to 5 GΩ. Whether it is a small resistor in a circuit or a large resistance in a power system, the PXI-4071 can handle it.

Other Measurements: In addition to the above, the PXI-4071 can also measure frequency/period and diode characteristics.

Digitizer Functions

High-Speed Acquisition: The PXI-4071 can acquire waveforms at a high speed of 1.8 MS/s. This is very helpful for capturing fast-changing signals, such as those in high-frequency electronic circuits.

Isolation: It has 1000 V isolation, which allows for safe and accurate measurement of high-voltage signals. For example, when testing high-voltage power equipment, the isolation function can protect the measurement system and operators.

Wide Voltage and Current Range: The digitizer can operate in all voltage and current modes supported by the digital multimeter, providing comprehensive waveform acquisition capabilities.
