National Instruments PXIe-4086 General Purpose 6½-digit PXI Express Digital Multimeter
The NI PXIe-4086 (part number: 790851-01) is a General Purpose 6½-digit PXI Express Digital Multimeter. The model integrates into PXI Express and CompactPCI systems. It supports DC voltage DC current AC voltage AC current frequency period and diode test functions. The model delivers ADC linearity of 0.5 ppm of reading plus 1 ppm of range. Its effective common mode rejection ratio exceeds 140 dB at DC with 100 ms aperture. Above 46 Hz, the ratio exceeds 170 dB with high-order DC noise rejection. The multimeter supports 105 percent overrange on most voltage and current ranges. This overrange excludes the 300 V range for voltage measurements. For DC and AC current ranges, the 1 A range is also excluded. These overrange margins accommodate signals that slightly exceed the selected range. The Digital Multimeter's input impedance is 1 megaohm with 2 percent tolerance and 150 pF capacitance. It supports both AC coupled and DC coupled input modes for voltage measurements. The maximum allowable DC voltage component on AC ranges is 250 V typical.
The NI PXIe-4086 PXI Express Digital Multimeter achieves common mode rejection ratio above 70 dB for AC voltage measurements. This specification applies across the DC to 60 Hz frequency range typical. The rating assumes a 1 kilo-ohm resistance in the LO lead. It includes a dedicated diode test function on fixed 10 V range. The available test currents include 1 µA, 10 µA, 100 µA, and 1 mA. The diode test accuracy adds 20 ppm of reading to the 10 V DC voltage specifications.
The PXIe-4086 measures frequency from 15 Hz up to 500 kHz. The period measurements range from 2 µs up to 66.67 ms. These capabilities support waveform characterization tasks in automated test systems. The trigger latency for AC voltage measurements on the model is 15 µs. For all other measurement functions trigger latency remains below 0 µs. It achieves a maximum reading rate of 15 kilosamples per second. The multimeter draws less than 9 W from the PXI Express backplane. The maximum current draw on the + 12 V and + 3.3 V rails is 0.55 A each.
