Fluke 343A
DC Voltage Calibrator
Description
This DC Voltage Calibrator is a 7 digit instrument with a basic accuracy of 20ppm and a resolution of 1µV on the 10µV range.
Cleanliness of the dc output is evident in the combined ripple and noise specifications of 50µV rms from the 343A.
Short term jitter and other random excursions are almost non existent, less than 1ppm.
