Description of settings
Source X
Defines the signal that supplies the x-values of the XY-diagram, replacing the usual
time base. The source can be any of the active analog channels.
Source Y
Defines the signal to be displayed in y-direction in an XY-diagram. The source can be
any of the active analog channels.
4.7 History (Option R&S RTH-K15)
The history option R&S RTH-K15 accesses the data of previous acquisitions and pro-
vides them for further analysis. Using this option, you can analyze, for example, packet
communication on serial buses, radar pulses, laser pulses, and signals that occur in
short bursts with long idle times.
If history is enabled and an acquisition runs, the instrument stores the captured wave-
forms, processes the data and displays the current waveform. Each stored waveform is
called a segment. When the acquisition is stopped, the history player is shown to
access the stored segments, and to display and analyze them. When you start a new
acquisition, the history is cleared and written anew.
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 RTH-B1).
Decoded bus data if the bus is active (with option R&S RTH-K1 and/or R&S RTH-
K2).
