Claims

[Scope of claim for utility model registration] Input for inputting measurement conditions consisting of measurement range data represented by start data and stop data, and a measurement point designation number sequence indicating the number of measurement points in each section where the measurement range is divided into equal parts. The device 11 determines the number of sections provided by equally dividing the measurement range and the number of measurement points in each section from the measurement point specified number sequence of the measurement conditions inputted by the input device 11, and determines the number of measurement points in each section. A measurement condition determination means 22 that sends the data to the next stage together with the data; a sweep data calculation means 24 that calculates each measurement point in the measurement range as sweep data based on the measurement conditions determined by the measurement condition determination means 22; Input power supply 4 that supplies power to the device under test 3 based on the sweep data from the data calculation means 24
, a sweeping means 26 for providing measurement conditions to the load device 5 serving as a load on the device under test 3 and the measuring instrument 6; and an image generating image data for displaying the data obtained by the measuring instrument 6 in the form of a graph or the like. Data generation means 27 and storage means 21 provided at each stage as necessary
