Description
The National Instruments PXIe-4081 (Part Numbers 783130-01 and 154888C-02L) is a highly precise 7½-digit Isolated Digital Multimeter that can measure voltages up to ±1,000 V and has a maximum digitizer sample rate of up to 1.8 MS/s.
This advanced multimeter boasts a wide digitizer voltage range of ±100 mV to ±1000 V, whether DC or AC coupled, and can measure current from ±1 µA to ±3 A, with a flexible sample rate range from 10 samples per second (S/s) to 1.8 million samples per second (MS/s).
With an input impedance of 10 MΩ ± 2% in parallel with 90 pF, and a maximum direct current (DC) voltage component of 400 V, this device is designed for diverse and demanding measurement tasks. Its frequency range spans from 15 Hz to 500 kHz, and it can measure periods ranging from 2 microseconds (µs) to 66.67 milliseconds (ms), which is indicative of its capabilities for various applications.
The PXIe-4081 also features exceptional analog-to-digital converter (ADC) linearity, up to 0.5 parts per million (ppm) of the reading plus an additional 0.5 ppm, ensuring accurate measurements. Despite its sophisticated functionality, the multimeter requires a 60-minute warm-up period to reach optimal performance. This warm-up time is essential for achieving the most accurate and reliable results.
