Adjusting Infinity IRS servo controller


I got a request from @bobterry99 about adjusting Infinity servo controllers.  Inside the controller are 4 pots:

Left side level (amplitude)

Left side DC offset

Right side level (amplitude)

Right side DC offset

See the attached photo.  I used a 2 ch oscilloscope to monitor the input and output while adjusting.  With 4 ch, you could monitor both channels...

DC offset is adjusted for minimum DC on the output. The level trim adjustments are just that.  Apply a similar signal to each input and adjust so that the outputs are equal.
