Abstract [en]
The Digital Sampling Wattmeter of SP has been upgraded. New resistive shunts and dividers are built, with lower temperature coefficient and less power dependence. The aperture time of the samplers are increased. The calibration methods are also upgraded by use of more direct AC/DC calibration. The goal of 10 μW/W seems to be within reach.
