Trigger Setup
RS-232 Bus Trigger Data Matching
You can trigger on a speci fi c data value for RS-232 bytes. If you de fi ned an end-of-packet character to use for RS-232 bus
decoding, you can use the same end-of-packet character 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.
Parallel Bus Trigger Data Matching
Optimum parallel bus trigger performance is achieved by using only analog channels or only digital channels (MSO4000 series only).
Checking Trigger Settings
To quickly determine the settings of some key
trigger parameters, check the Trigger readout
at the bottom of the display. The readouts differ
for edge and the advanced triggers.
1. Trigger source = channel 1.
2. Trigger slope = rising.
3. Trigger level = 0.00 V.
