Trigger Setup
!=, <, >, >=, and <= operations. Triggering on identifier and data always matches the identifier and data selected by
the user, w ith t
he data starting at the first byte. No rolling window is used.
For FlexRay an
d Ethernet, triggering occurs when the user-selected data input matches the data and qualifier in the
signal starting at the byte offset. Set the number of bytes to match the number of bytes of interest. Use the data qualifier
to perform: =, !=, <, >, >=, and <= operations. Triggering on identifier and data always matches the identifier and data
selected by th
e user, with the data starting at the first byte. No rolling window is used.
Data Value Matching
You can trigger on a specific data value for RS-232 bytes. If you defined an end-of-packet character to use for RS-232 bus
decoding, you can use the same end-of-packet c haracter as a data value for trigger data matching. To do so, choose the Tx
End of Packet or the Rx End of Packet character as the Trigger On selection.
You can also trigger on a specific data value for other buses.
Parallel Bus Trigger Data Matching
Optimum p
arallel bus trigger performance is achieved by using only analog channels or only digital channels.
Checking Trigger Settings
To quickly determine the settings of some
key trig
ger parameters, check the Trigger
readout at the bottom of the display. The
readouts differ for edge and the advanced
trigge
rs.
1. Trigge
r source = channel 1.
2. Trigg
er slope = rising.
3. Trigg
er level = 0.00 V.
