14.4 UART Trigger and Serial Decode
This section covers triggering and decoding UART signals. Please read the following for more details:
"UART Signal Settings", "UART Trigger" and "UART Serial Decode".
14.4.1 UART Signal Settings
Connect the RX and TX signals to the oscilloscope, set the mapping relation between channels and
signals, and then set the threshold level of each signal. The process of specifying the source and
threshold is similar to "I2C Signal Settings".
In the BusConfig menu of trigger or decode, the following parameters are available:
A. Click to select the baud rate: 600,1200, 2400,
4800, 9600, 19200, 38400, 57600, 115200 b/s
or Custom
B. Data Length: 5~8 bit
C. Parity Check: None, Odd, Even, Mark, or
Space. If the data is 9 bits, the 9
th
bit is treated
as Mark parity or Space parity
D. Select the number of stop bits
E. Set the idle level
F. Set the bit order
G. Return to the previous menu
The method of copying settings is the same as I2C signal settings. See "I2C Signal Settings" for details.
