How to use Electronic Load to acquire the V&I transient waveform rapidly?
When performing Dynamic current test on SMPS, users have to use an Oscilloscope to capture the transient voltage and current waveform to log the Vpk+ and Vpk- value. The 63600 Series Load Modules have digitalized data acquisition function that users can set the sampling interval range to be 2 microseconds – 40 milliseconds and the total sampling measurement log to be 1 - 4096 dots. The data can be read by digital interface and the waveform can be logged and converted to graphic file for analysis. The digitalized data acquisition function has two built-in fast A/D(500KHz) synchronization V&I signals that allow users to do analysis to get Instantaneous Power, Voltage Peak, Voltage Rise and Fall Timing as well as the average current of Hiccup.
Real Time precision measurement of voltage and current for Energy Star and 80 Plus efficiency Measurement requirements!
For example:model 63610-80-20 has three ranges measurement circuit of current (0.2A/2A/20A) and voltage(6V/16V/80V), accuracy of current for 0.05%+0.05FS, accuracy of voltage for 0.025%+0.01%FS, the current error tolerance will be +/-0.15mA if input 0.1A; the voltage error tolerance will be +/- 1.425mV if input 3.3V.
PS: Users can set the voltage and current window time: 1ms – 10s to get more accurate measurement or fast remote test command execution.
