2.8.7.3
This field allows the user to select the type of windowing algorithm for FFT processing. Windowing algo-
rithms include the Blackman, Blackman-Harris, Hanning, 5-term Hodie, and 7-term Hodie. The 5-term
Hodie and 7-term Hodie are windowing algorithms developed at Crystal Semiconductor.
2.8.7.4
This field determines the "bin width" when plotting histograms of the collected data. Each vertical bar in
the histogram plot will contain the number of output codes within a bin range. Decreasing this number may
allow the user to view histograms in more detail.
2.8.7.5
These three check boxes allow the user to select the data types that will be collected and returned to the
PC for processing.
2.8.7.6
The value in the Cycle Count field will be written to the Cycle Count register in the CS5460A. The Cycle
Count register determines the length of one computation cycle. The Cycle Count value should be selected
appropriately according to the Data to Collect setting. For example, if the Data to Collect is instantaneous
current, voltage, or power it is better to set Cycle Count to 1.

When this button is pressed, the current settings will be saved, and the user will return to the Data Col-
lection window.

2. Select the appropriate settings from the available options (see the Configuration Window section) and press
3. The Data Collection window should still be visible. Press the Collect button to begin collecting data.
4. Once the data has been collected, it can be analyzed, printed, or saved to disk.
1. Pull down the Setup menu and select the Disk menu item. A file menu will appear.
2. Find the data file in the list and select it. Press the Select button to return.
3. Go to the Data Collection window, and press the Collect button.
4. The data from the file should appear on the screen. The data will be ready for different types of analysis.
