Timing Units (Smpl/sec) Controls: Gen Dlg >> Stream >> Smooth TC >> Smpl/sec
The button to the right of the Smooth TC control shows units of samples (Smpl) or seconds (sec). You can toggle between these by clicking the button, which also changes the Timing Shift control units to match, as well as the Shift Timing Modulator dialog. If Step mode is active, it also affects the format of Step Size. 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 same button appears in other Generator dialogs, as well as the Trigger dialog, and setting the current units anywhere affects all dialogs alike. This doesn't change anything in the actual output, only the display and data entry format. It can be toggled back and forth as needed to see the equivalent samples or time. 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. Note that this command affects the expected values for TmStepSize, TmSmoothTC, and TmShift, as well as the Shift Modulation TmModDepth command.
