Modulation delay and jitter
Set the current using the internal setpoints to 0.5 A / 1 A. Use a 1 ohm load. Apply square modulation at the isolated modulation input. Observe the modulation voltage as well as the load voltage. Measure the delay on the rising / falling edges. Try to determine if jitter is present. Use 5.0 V and 3.3 V input as logic 'high' for the opto coupler. Outline in the documentation that the opto coupler logic 'high' voltage is directly influencing the signal delay.
