Measuring the Horizontal Scale
The following procedure enables you to manually measure
horizontal timing details on a waveform and display the
period and frequency of the waveform.
This procedure assumes that the oscilloscope retains
the settings from the previous procedure.
To measure horizontal timing details on a waveform,
follow these steps:
1. Push the appropriate side-screen menu button to select
Type Time .
2. In the HORIZONTAL section, turn the SEC/DIV knob
clockwise to set the readout at the bottom of the screen
to

3. Ensure that Cursor 1 is selected. Turn the
Multipurpose knob to position the associated cursor on
the left of the waveform cycle where the sine wave
crosses negatively through the center display graticule
line.
4. Select Cursor 2. Turn the Multipurpose knob to
position the associated cursor on the right of the
waveform cycle, where the sine wave crosses
negatively through the center display graticule line.
