Tfx Command
(requires ENG access)
foc act resp

Description This command is used to measure the response of the focus actuator to arbitrary current waveforms. The user is prompted to load a waveform file, the file contains the length of the file and a list of uncalibrated (ie. raw DAC value) commanded actuator currents.

The waveform is applied to the input of the focus actuator driver and the hall sensor response is recorded. The resulting data is displayed on the monitor in the following format:

<Actuator current> <Measureed lens position>
