* Notes
* When used with multiple active components, transient analysis may have a longer\nsimulation time. For faster run time, do the following:\n1. Use .option noopiter\n2. Use the ADAQ4380 model to simulate the performance of the two channels.\n \nEach ADAQ4380-4 channel is set to different gain configurations just for simulation.\nRefer to ADAQ4380-4 datasheet on how to correctly set the gain per channel.
