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.
PROTocol
The protocol search finds various events in decoded data of sig-
nals, for example, a specified frame type, identifier, data, and
errors. Available search settings depend on the configured bus
type.
Protocol search is not available for bus types PARallel, I2C, SPI
(no CS), SPI (with CS), UART, and I2S (Audio).
WINDow
The window search finds violations of a window that is formed
by the upper and lower voltage levels. An event occurs if the
waveform enters or leaves the window, or if the waveform stays
inside or outside for a time longer or shorter than specified, or if
the waveform passes both levels in a given time.
*RST:
EDGE
SEARch:SOURce
<SearchSource>
Selects the waveform to be analyzed.
Parameters:
<SearchSource>
CH1 | CH2 | CH3 | CH4 | QMA | RE1 | RE2 | RE3 | RE4
Any active channel, math, or reference waveform can be
searched.
For protocol search on CAN and LIN signals, an active serial
bus is the search source.
