The soft buttons are assigned with different functions:

Press F1 to select one of the acquisition modes:

When the Acquisition Mode is not Free Run, the Trigger Source, Trigger Condition must be defined.

Press F2, Trigger Source, to select one of the time streams as the trigger source. These time streams are set as Trigger Source Candidates by the CSA Editor when this CSA project is created on the host PC.

Press F3, Trigger Cond., to select one of the trigger conditions. You can also key in the trigger level(s) using Editing Level entry.

The arrow buttons can also be used to set the trigger level and delay settings.

Use the arrow buttons to change the trigger level and delay while the data stream from the trigger source is displayed.

Press F4 to activate one of four functions for the navigation arrow buttons

1. Auto Scaling Window

2. Fixed Scale Window: Arrow buttons used for expanding or reducing the scales

3. Moving window: Arrow buttons used to shift the positions of the window

4. Arrow buttons are used to set the high threshold level, low threshold level, and trigger delay

The method 3 is a more convenient way to set the trigger threshold level instead of using the editing tool under F3.  The editing tool allows you to set the trigger level to a precise value.

Press F5 to set the overlap rate. This factor will only have effect when the acquisition mode is set as Free Run or Continuous after Trigger.

After all trigger parameters are set, press F6 (OK) button then the system will exit to the main measurement display window.
