Tfx Command
(requires ENG access)
adc info

Description Displays A/D conversion subsystem information on the elements where each element consists of one or two A/D samples. If the element has two A/D samples, then the A/D conversion subsystem will display the following information:

<Index> <Description> <Callback> <Counter> <Sample #0>/<Sample #1>

If the element has one A/D sample, then the A/D conversion subsystem will display the following information:

<Index> <Description> <Callback> <Counter> <Sample>

The element index is used for streaming A/D samples using the monitor command adc stream (on <element>|off).

The element description is the name of the element. For Tfx, the element description will identify one of the following elements:
  • Focus Difference/Sum
  • Focus Laser Current
  • Focus Laser Calibration
  • Lens Position
  • Head Power
  • Focus Temperature
  • Spare Element
For Thermal 2, the element description will identify one of the following elements:
  • Focus Difference/Sum
  • Focus Laser Current
  • Focus Laser Calibration
  • Lens Position
  • Write Laser
  • Focus Temperature
  • Beam Balance
  • Beam Pointing

The callback determines if an interrupt handler is acquiring the samples. The callback will be one of the following:
  • Installed
  • Not Installed

The element counter displays the number of A/D samples that have been acquired for the element. Most of the elements are sampled at a pre-determined rate and this field can be used to determine the elapsed time between samples. This field is intended for data analysis.

The A/D samples are twelve-bit numbers representing the sample data. The A/D conversion subsystem will display the numbers in hexadecimal and will not attempt to interpret the format of the sample data.

This is intended as a development tool and should not be used during normal operation.

Notes Thermal 1.0 / 1.7x equivalents:
  • The monitor command adc info does not have an equivalent.
