Burst Units (Samples, Seconds)


Macro: SmplSec

The button to the right of the Burst Lag control shows units of samples (Smpl) or seconds (sec). You can toggle between these by clicking the button, which changes the display and data entry format for all of the timing-related items, both in the Burst dialog and the other dialogs that have copies of this control (Sweep, Timing and Play), as well as the Trigger dialog.

This allows you to work in whichever format you find most relevant for your application. You can toggle back and forth as needed to see the equivalent samples or time.

The burst durations are always stored internally as samples; if you enter a value in seconds, you may not see the same value you typed since Daqarta shows the value that is actually used.

Note that for fractional seconds entry, you can use scientific prefixes to make things simpler, such as '1m' (for 1 millisecond) instead of '0.001'.

In seconds mode, you can enter values in H:M:S format even though Daqarta will only display seconds. For example, if you enter '1:30:0' Daqarta will show 5400 seconds.


Macro Notes:

SmplSec=sec sets the units to seconds, as does SmplSec=1. SmplSec=Smpl or SmplSec=0 sets Samples, and SmplSec=x toggles between the two.
