The history stores the following data during acquisition:
●
All active analog channels.
●
All logic channels if at least one logic is active (with option R&S
RTB-B1).
●
Decoded bus data if the bus is active (with at least one serial protocol option, for
example, R&S
RTB-K1 or K2).
Fast segmentation
During normal acquisitions, only a short time of the acquisition cycle is used for sam-
pling; processing and display take most of the time. The processing and display time is
blind time causing a gap in the recorded signal. Usual acquisitions can miss very short-
time and infrequent events occurring during the dead time.
To reduce the dead time and thus the probability of missed events, fast segmentation
is provided. Fast segmentation takes effect for [Single] acquisitions if "Nx
Single" > 1.
With fast segmentation, subsequent triggered acquisitions are captured very fast, with
hardly any dead time between the acquisitions. After the acquisition of all segments
has been completed, the data is processed and the latest waveform is displayed.
Using the history viewer, you can view and analyze all stored waveform segments.

Activating the history
To activate the history
1. Tap the "Menu" icon.
2. Select "History".
3. Enable "Show History".
The segment table and the history player are shown.
4. Stop the acquisition.
The captured segments are listed in the segment table, and the buttons in the his-
tory player are active.
To disable the history
► In the history player, tap "Exit".
If you close only the segment table, you can use the history player and see the
waveform segments in greater detail. To open the segment table again, open the
"History" menu, and tap "Show History".

History settings
History and segmentation settings are located in the "History" menu. The "Acquisition"
provides an additional setting: "Nx
Single".
