The application
Parameter_sweep.py
creates a ramp at an AUX Channel. It calls the DLL
function SetLockinAUX(Channel, Input, Voltage). “Channel” selects between the AUX Channel
either to be 0 (AUX1) or to be 1 (AUX2). The “Input” defines which of the available input signals is
displayed: In → 0; X → 10; Y → 11; R → 12; Phi → 13.
Finally, it displays two graphs: In over AUX
and
AC - R over AUX.
