and "Result position" on page 107.
8.1.1.1 Cursor measurements on time-based waveforms
The cursor for measurement on time-based waveforms returns the following results.
The results are displayed automatically when a cursor measurement is enabled.
Figure 8-1: Measurement results of a cursor measurement in time domain
Label Description
X1, X2 Time at the position of the vertical cursors.
Y1, Y2 Vertical values of the waveform at the position of the horizontal cursors in V or
A.
ΔX Difference between the vertical cursor (time) values
ΔY Difference between the horizontal cursor values
1/ΔX Inverse time difference
ΔY/ΔX Slope of the waveform between the cursors (if measured on one source)
8.1.1.2 Cursor measurements on spectrum waveforms
If the measurement source is a spectrum waveform, the results have a different mean-
ing. Measurement on 2 spectrum waveforms is not possible.
The result box for measurement on spectrum waveforms shows the following informa-
tion.
Label Description
X1, X2 Frequency at the position of the vertical cursors
Y1, Y2 Vertical values of the waveform at the position of the horizontal cursors in dB.
Bw Difference between the vertical cursor (frequency) values
ΔY Difference between the horizontal cursor values
To set the cursor lines to the peaks, various functions are available in the "Peak
Search" tab, see Chapter 8.1.3.3, "Peak search tab", on page 328.
8.1.2 Using cursors
You can start cursor measurements by using the "Cursor" icon on the toolbar, or using
the [Cursor] key. For detailed configuration, use the "Cursor" dialog box.
