   NATIONAL INSTRUMENTS PXIE-4080   Description / Specification:    
NATIONAL INSTRUMENTS PXIE-4080 6.5 Digit, 300V, 1.8MS/s Isolated Digitizer, PXI Multimeter

The National Instruments PXIe‑4080 is a high-performance 6½‑digit, 300 V DMM that provides the measurement capabilities found in two common test instruments: a high-resolution DMM and a digitizer. As a DMM, the PXIe‑4080 delivers fast, accurate AC/DC voltage, AC/DC current, 2‑ or 4‑wire resistance, and frequency/period measurements, as well as diode tests. In the high-voltage, isolated digitizer mode, the PXIe‑4080 can acquire waveforms at sample rates up to 1.8 MS/s.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
