Timing
======

KAPTURE is able to delay each of the four ADCs. To control this you can use the timing window.

You can open it via the menu, Windows -> Timing, via the fourth toolbar button or by pressing Ctrl+t.

Toolbar Symbol for timing window:

The timing window looks as follows.

Here you can set the coarse delay which affects all four ADCs and the fine delay for each ADC individually.

.. note:: These values are directly written to the board.

.. note:: Timing settings and time scan is only available if you calibrated and synchronized your board

Time Scan
---------

To detect the best delay settings you can use a feature called time scan.

To perform a time scan you have to open the time scan part of the timing window by selecting Time Scan at the bottom
of the timing window.

The timing window with activated time scan part looks as follows.

You can set the range for the coarse and fine delay. To start the time scan simply click on the `Start time scan` button.

You can interrupt the time scan by clicking on the same button which reads now `Stop time scan`.

After a time scan the result will be shown in a seperate window which consists of four plots, one for one ADC each.
You can either manually read the best value or click on the region with the best setting. By clicking on the region,
the values will automatically be taken into the timing window and are written to the board.

.. caution::
    The coarse delay will be updated no matter on wich ADC you click. That means always the last value you clicked
    for the coarse delay will be taken.

Above the plots the maxima for this ADC in terms of coarse delay and fine delay will be shown.

The time scan results window looks as follows.
