5 Measurements
Using the R&S RTO you can perform and display different measurements simultane-
ously, based on the active signal or math waveforms. The color of the results in the result
table corresponds with the source waveform color.
The following measurement methods are available:
●
Cursor measurements (CURSOR key): measurements can be configured for up to
four cursor sets to determine specific results at the manually defined cursor positions
of an active waveform; the results are displayed in a result box.
See chapter 5.1, "Cursor measurements", on page 121.
●
Automatic measurements: up to eight measurements can be configured and per-
formed simultaneously; the results are displayed in a result box. The MEAS key starts
the default measurement for the active waveform. If a measurement is still running,
the key opens the configuration dialog box.
See chapter 5.2, "Automatic Measurements", on page 129.

5.1.1 Manual Measurements with Cursors
Cursor measurements determine the results at the current cursor positions. The cursors
can be positioned manually or can be configured to follow the peaks of the waveform. Up
to four sets of cursors can be configured and displayed. Each set of cursors consists of
a pair of horizontal or vertical cursors, or both. Cursors can be coupled so that the initially
defined distance is always maintained.
How to set up cursor measurements is decribed in chapter 5.1.2, "Performing Cursor
Measurements", on page 122. The chapter 5.1.3, "Reference for Cursor Measure-
ments", on page 125 provides a detailed description of all settings.
Cursors also can define a gate to limit the measurement to the section of the waveform
between the cursor lines. See chapter 5.2.3.7, "Measurements - Gate/Display
Tab", on page 170.
Cursor Measurements Results
The results of cursor measurements are displayed in a result box on the screen. For each
measurement, a separate result box is displayed. The result box is displayed automati-
cally when a cursor measurement is enabled. Similar to waveform diagrams, you can
minimize the result box to a result icon on the signal bar, and display results in a separate
diagram on the screen.
