4.4 Changing the Waveform Scaling and Position
As you can see on the y-axis of the display, the calibration signal has a vertical offset
of about 550 mV. The value can differ.
This value is also indicated in the signal icon for channel1 (2nd row). If you press the
CH1 key, the "Vertical" settings dialog box also displays the "Offset" value. The offset
is the DC component of the signal.
If you use a passive probe, you can filter the DC component by using the AC Coupling
function, then quickly find the new trigger level, and try out the scaling functions:
1. Press the CH1 key on the front panel (in the VERTICAL area) to display the "Verti-
cal" dialog box.
2. Change the "Coupling" to AC, and close the dialog box.
The DC component of the signal is eliminated; the waveform position moves down
vertically and is now centered around 0 V.
