Gated Power Measurement Description
• For the falling trace, data points 4894 through 5264 (the last 371) are displayed with each data point
occupying one display pixel.
• For the Full/Zoomed trace spanning the entire 1277 uS measurement period, averaging over groups of data
points will be performed to include all 5,264 data points using the display’s 371 pixels.
• For the Full/Zoomed trace that zooms in on the area highlighted by the vertical bar, the correlation between
data points and pixels is as follows:
— For the first or last zoomed segment the correlation between data points and display pixels will be
identical to the Rise/Fall traces, with the first or last 371 data points displayed on 371 pixels.
— For all of the middle 12 zoomed segments, the time period (when compared with rise/fall graphs) will be
compressed in time. Each data point will span a time period four times longer than the rise/fall data
points. This will result in about one fourth the display resolution when compared with the rise/fall
traces.
