Frequency Sweep Units (Samples, Seconds)


Macro: SmplSec

The button to the right of the Sweep Length control shows units of samples (Smpl) or seconds (sec). You can toggle between these by clicking the button, allowing entry and display in whichever format you find most convenient.

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.

This is one of several duplicate buttons that affect duration entry and display throughout the Daqarta Generator, and also the Trigger dialog.


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.
