Measurement of Cross response waveform and Ripple Voltage in multi-output power supply With 4 channels, when measuring the output coupling voltage of the multi-output power supply and the output voltage of the transient response, the measurements had to be taken in two rounds. With the DL7480, 8-channel measurement is possible, so the fluctuation band and the output coupling voltage per the transient responses can be observed in a single measurement.
