Raw-Grabbing Acquisition Mode

When the board is configured for raw grabbing:

FVAL timing diagram (area-scan acquisition mode)

If the acquisition trigger is armed when FVAL rises, the board acquires all data until FVAL goes down.

You can configure the frame grabber to use the DVAL signal as a clock qualifier but this feature is rarely used. By default, the configuration ignores the DVAL signal. When DVAL is enabled, the data acquisition is inhibited for clock cycles where DVAL = 0.
