   NATIONAL INSTRUMENTS PXIE-4082   Description / Specification:    
NATIONAL INSTRUMENTS PXIE-4082 6.5 Digit, 300V, LC, 1.8MS/s Isolated Digitizer, PXI Multi

The National Instruments PXIe‑4082 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‑4082 delivers fast, accurate AC/DC voltage, AC/DC current, 2‑ or 4‑wire resistance, frequency/period measurements and basic L and C measurements, as well as diode tests. In the high-voltage, isolated digitizer mode, the PXIe‑4082 can acquire waveforms at sample rates up to 1.8 MS/s.

Carrier Wave (CW)
Carrier Wave or Continuous Wave is a sinusoidal signal without modulation.

Harmonic
A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc.

Noise Floor
Noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system.

Ripple
Ripple is the small unwanted residual periodic variation of the direct current (dc) output
