FLUKE 192, 196, 199 Supplement 电路图.pdf

ScopeMeter192/196/199 Manual Supplement Using Waveform Math Functions When adding, subtracting, or multiplying the input A and input B waveform, the test tool will display the mathematical result waveform and the input A and input B waveforms. A versus B provides a plot with input A on the vertical axis and input B on the horizontal axis. The math functions perform a point-to-point operation on waveforms A and B. To use a math function, do the following: 1 Display the SCOPE key labels. 2 Open the Waveform Options menu. 3 Jump to Waveform: and Select Mathematics. to open the Mathematics menu. 4Select Function: A+B, A-B, AxB or A vs B. 5Select a scale factor (not for A vs B) to fit the mathematical result waveform onto the display, and return. The sensitivity range of the mathematical result is equal to the sensitivity range of the least sensitive input divided by the scale factor. 2000 Fluke Corporation. All rights reserved.

For other cursor measurements on a Math waveform amplitude no reading will be available if the input A and input B measurement unit are different. Making Rise Time Measurements To measure rise time, do the following: 1From scope mode, display the cursor key labels. 2Press to highlight (rise time). Observe that two horizontal cursors are displayed. 3If only one trace is displayed, select MANUAL or AUTO (this automatically does the steps 4 to 6). For multiple traces select the required trace A, B, or M (if a Math function is active). 4Move the upper cursor to 100% of the trace height. A marker is shown at 90%. 5Highlight the other cursor. 6Move the lower cursor to 0% of the signal height. A marker is shown at 10%. The reading shows the rise time from 10%-90% of the trace amplitude.
