5.2.1 Measurement Types and Results
Various measurement types are available, depending on the selected source.
Time domain
Amplitude and time measurements
Eye/Jitter measurements
Histograms
Frequency domain
Spectrum measurements
Histograms
Default measurements
The default measurement is started when you tap the "Measurement" icon on the toolbar
or press the MEAS key.
The default measurement depends on the type of the source waveform:
amplitude measurement for analog time domain waveforms
extinction ratio (%) for eye/jitter measurements
channel power measurement for frequency domain waveforms
waveform count for histograms
positive pulse measurement for digital channels (MSO option R&S RTO-B1)
Note that the "Measurement" icon and the MEAS key always configure and start a new
default measurement for the selected waveform. Any previous configurations for that
measurement are overwritten. If no measurement is currently running, pressing the
MEAS key has the same effect. To recall a previously configured and disabled measure-
ment, select the "Meas > Setup" menu item.

Multiple measurements
By default, only one measurement is performed for each active type for best performance.
However, you can enable multiple measurement, for example to measure the rise time
for several cycles in one waveform. This is particularly useful when statistics are evalu-
ated.
