Figure 8. Setup Window
2.4.1 Refresh Screen Button
The Refresh Screen button will update the contents of the screen by reading all the register values from the
CS5461A device. It is a good idea to press the Refresh Screen button when entering the Setup window, or after
modifying any registers to reflect the current status of the device.
2.4.2 Reset DUT Button
The Reset DUT button will hardware reset the CS5461A. The CS5461A will perform a reset as discussed in the
CS5461A data sheet. After the hardware reset to CS5461A, the screen contents will be automatically refreshed with
the updated status of the CS5461A device.
2.4.3 CS5461A Crystal Frequency
The CS5461A accepts a wide range of crystal input frequencies, and can therefore run at many different sample
rates. The crystal frequency being used on the CS5461A should be entered in this field to provide accurate frequen-
cy calculation in the FFT window. This will also help the software decide which functions can be performed reliably
with the evaluation system.
