Control Panel Button
Pressing the
Control Panel
button brings up a display panel that allows you to adjust each channel using
a set of graphical sliders, as shown in
. Simply drag the slider to adjust the desired channel
output. The DAC code and corresponding output value of each channel change automatically. This
function is similar to the slider present on the primary BUF16821EVM-USB software window that changes
based on the channel that highlighted (as discussed in the
).
