2.8.5 Zoom Button
This button allows the user to zoom in on the plot by selecting two points in the plot area. Press the Re-
store button to return to the normal data plot, or press the Zoom button again to zoom in even further.
2.8.6 Channel Select Button
After data collection, the two buttons labeled as “No Data” will be replaced with Current and Voltage but-
tons, allowing the user to choose the appropriate channel for display. In the time domain mode, an addi-
tional Overlay button will be present which allows the user to display all the channels on the same plot.
2.8.7 Configuration Window
The Configuration window allows the user to set up the data collection and analysis parameters.

2.8.7.1 Number of Samples
This field allows the user to select the number of samples to collect, between 16 and 32768.
2.8.7.2 Average
When performing FFT analyses, this field determines the number of FFTs to average. FFTs will be col-
lected and averaged when the Collect button is pressed.
2.8.7.3 FFT Window
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.
