Initial source voltage and measure voltage tests are impressive:
Source and measure 0.1 volt with remote sensing to the 8846A 2.6µV difference in measured value or 26ppm. Max 8846A error for 1 year is +/-6µV Max 2450 error for 1 year spec +/- 212µV
Source and measure 1.0 volt with remote sensing to the 8846A 4.9µV difference in measured value or 4.9ppm. Max 8846A error for 1 year is +/-25µV Max 2450 error for 1 year spec +/- 420µV
Source and measure 10.0 volt with remote sensing to the 8846A 13.7µV difference in measured value or 13.7ppm. Max 8846A error for 1 year is +/-230µV Max 2450 error for 1 year spec +/- 2500µV
The 2450 spec on current is
way way way better than the 8846A below 0.1A so the only place I can use the 8846A to check is at 400mA where it is 3x more accurate than the 2450
Source and measure 400mA to the 8846A 80µA difference in measured value or 201ppm. Max 8846A error for 1 year is +/-180µA Max 2450 error for 1 year spec +/- 620µA
Looks like a winner.
