"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 6.5.7, "Runt setup" , on page 124.
"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 6.5.8, "Data2Clock" , on page 125.
"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 6.5.9, "Pattern search" , on page 127.
"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.

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.
Remote command:
SEARch:SOURce

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.

6.5.3 Edge search
Similar to the edge trigger, an edge search result is found when the waveform passes
the given level in the specified direction.
