NIDisk User Guide

Acquisition/Playback Summary Screen

After closing the acquisition/playback parameter screen, NIDisk displays a summary of the

acquisition/playback parameters, showing the actual sample rate, gain, number of channels,

destination filename(s), required disk space, and other information. NIDisk does not check

for sufficient disk space before acquiring, so be sure the required space is available on the

disk. Acquisition and playback will begin when the user clicks OK (Manual triggering) or

after the user clicks OK and applies the external trigger (External triggering).

7. Acquisition and Playback Progress Screens

During acquistion and playback, NIDisk displays a progress screen containing:

• Numerical readout of elapsed acquisition time

• Numerical readout of current signal headroom

• Graphical bar display of elapsed acquisition time

• Graphical bar display of current headroom

Click Stop to halt the acquisition or playback before it completes. If acquisition is halted in

this way, sound data recorded up to that point is saved.

The meter also provides a summary display of total I/O time and total headroom when

acquistion or playback has completed. See the figures.
