Starts the measurements of the selected measurement group.
Remote command:
MEASurement<m>[:ENABle] on page 1360
Category
Measurement category. The following categories are available:
Time domain:
●
Amp/Time: amplitude and time measurements
●
Eye: eye diagram measurements
●
Histogram: measurements on histograms
●
Jitter measurements (available if one of the jitter options is installed)
●
Protocol: advanced analysis (available if option R&S RTP-K35 is installed)
Frequency domain
●
Spectrum: measurements on spectrum waveforms
●
Histogram: measurements on histograms
Remote command:
MEASurement<m>:CATegory on page 1363
Source, Source 2
Define the source of the measurement group. The 2nd source is required for ampli-
tude/time measurements that are performed on two waveforms (e.g. delay, phase).
Availability of sources depends on the selected category and installed options.
Remote command:
MEASurement<m>:SOURce on page 1361
Active measurements, Add / Remove
The "Active Measurements" list shows the measurements that are selected for the cur-
rent category. At least, one measurement must be selected. If further settings are avail-
able for a measurement, a settings icon is shown beside the measurement's name.
To change the selection, tap "Add / Remove Measurements".
In the "Add / Remove Measurements" dialog box, select the measurements that you
need. Tap "Clear" to disable all selected measurements. Tap "OK" to confirm the selec-
tion.
Remote command:
MEASurement<m>:MAIN on page 1364
MEASurement<m>:ADDitional on page 1365
Envelope
This setting is only available for measurements on envelope waveforms, see "Wfm
Arithmetic" on page 152.
"Both"
The upper and the lower envelope are used in measurements. For
time measurements, the averages of min and max values are used,
that is, the measurement is performed on the average waveform built
from the upper and lower envelope.
"Maximum"
Measurements are performed on the upper envelope.
