Seamless Measurement Ranging

Seamless measurement ranging eliminates the challenges of measuring dynamic currents. With seamless measurement ranging, engineers can precisely measure dynamic currents without any glitches or disruptions to the measurement. As the current drawn by the DUT changes, the SMU automatically and instantaneously detects which current measurement ranges will return the most precise measurement and changes to that range seamlessly. When combined with the SMU's built-in 18-bit digitizer, seamless measurement ranging enables unprecedented effective vertical resolution of 28-bits. This provides unrivaled productivity gains and insights into power consumption by enabling engineers to see the complete current waveform they have never seen before, from nA to A, in one pass and one picture.
