Tfx Command
(requires ENG access)
foc act lin [<Max Cur> <Min Cur> <Step size> <Sample size>]

Variables Max Cur The maximum actuator current for the measurement.
Min Cur The minimum actuator current for the measurement.
Step size The actuator current step size between data points.
Sample size The number of samples taken and averaged at each current level.

Description This command measures and displays the lens position, as read from the hall sensor, over a range of focus actuator currents. The measurement is done for acsending currents and then for decsending currents. The data is displayed as follows:

<Actuator current> <Lens Position>

If no parameters are entered the defaults are:

  • <Max Cur> = 3.0 amps
  • <Min Cur> = 0.0 amps
  • <Step size> = 0.1 amps
  • <Sample size> = 1
