UART/RS232 Triggering
To set up the oscilloscope to capture UART/RS-232 signals, see
To trigger on a UART (Universal Asynchronous Receiver/Transmitter) signal
connect the oscilloscope to the Rx and Tx lines and set up a trigger condition.
RS232 (Recommended Standard 232) is one example of a UART protocol.
1
Press
[Trigger]
.
2
In the Trigger Menu, press the
Trigger
softkey; then, turn the Entry knob to
select the serial slot (Serial 1 or Serial 2) on which the UART/RS232 signals are
being decoded.
3
Press the
Trigger Setup
softkey to open the UART/RS232 Trigger Setup Menu.
4
Press the
Base
softkey to select Hex or ASCII as the base displayed on the Data
softkey in the UART/RS232 Trigger Setup Menu.
Note that the setting of this softkey does not affect the selected base of the
decode display.
5
Press the
Trigger
softkey and set up the desired trigger condition:
•
Rx Start Bit
— The oscilloscope triggers when a start bit occurs on Rx.
•
Rx Stop Bit
— Triggers when a stop bit occurs on Rx. The trigger will occur on
the first stop bit. This is done automatically whether the device under test
uses 1, 1.5, or 2 stop bits. You do not need to specify the number of stop bits
used by the device Under test.
•
Rx Data
— Triggers on a data byte that you specify. For use when the device
under test data words are from 5 to 8 bits in length (no 9th (alert) bit).
