"Runt"
The runt search finds pulses lower than normal in amplitude. In addi-
tion, you can define a time limit for the runt.
For settings, see Chapter 7.5.7, "Runt setup", on page 139.
"Data2Clock"
The Data2Clock search - also known as setup/hold - finds violation of
setup and hold times. It analyzes the relative timing between two sig-
nals: a data signal and the synchronous clock signal.
For settings, see Chapter 7.5.8, "Data2Clock", on page 140.
"Pattern"
The pattern search finds logical combinations of channel states inside
or outside a specified time range. For each channel, its state and
threshold level is defined. The states are combined logically, and the
time of true pattern results is compared with a specified time range.
For settings, see Chapter 7.5.9, "Pattern search", on page 142.
"Protocol"
The protocol search finds various events in decoded data serial sig-
nals. The events are protocol-specific and correspond to the trigger
settings of the serial protocol.
"Window"
The window search checks the signal run in relation to a "window".
The window is formed by the upper and lower voltage levels. The
search condition is fulfilled, if the waveform enters or leaves the win-
dow, or if the waveform stays inside or outside for a time longer or
shorter than specified.
For settings, see Chapter 7.5.10, "Window search", on page 144.

Source
Selects the waveform to be analyzed by search. Available sources depend on the
selected search type.
Edge, width and pattern search you can perform on analog and logic channels. Peak,
rise/fall and runt search are possible on active analog channels, math and reference
waveforms. For Data2Clock search, you need two active analog channels.
For protocol search, select the configured bus.

Setup
Opens a menu to define the search parameters for the selected search type.
Track event
If enabled, the selected result is moved to the reference point. Thus you can always
see the selected event in the diagram.
Save
Opens a dialog box to save the search results. The file format is CSV.
