Vertical Cursors on a Waveform
To use the cursors for a time measurement (T, 1/T), for a mVs-mAs-mWs measurement, or for an
RMS measurement of the waveform section between the cursors:
1. From Scope mode, press
G to show the cursor key labels.
2. Press 1 to highlight the vertical cursor icon.
3. Press 3 to choose, for example, time measurement: T.
4. Press 4 to choose the waveform to place the markers: A, B, C, D or M (Mathematics).
5. Press 2 to highlight the left cursor icon.
6. Use
g f to move the left cursor position on the waveform.
7. Press 2 to highlight the right cursor.
8. Use
g f to move the right cursor position on the waveform.
The screen shows the time difference between the cursors and the voltage difference
between the two markers. See Figure 23.
Figure 23. Time Measurement with Cursors
9. Press 4 to select OFF and turn off the cursors.
Note
For an mVs-mAs-mWs measurement:
- mVs: select probe type as Voltage
- mAs: select probe type as Current
- mWs: select the mathematical function as x, probe type as Voltage for one channel, and
Current for the other channel
