bus trigger and decode
UART trigger configuration menu descriptions:
a) Start bit — trigger at the start bit of the measured signal
b) Stop bit —trigger at the stop bit of the measured signal, no matter the measured signal
uses 1, 1.5, or 2 stop bits or not, the trigger will occur at the first stop bit.
c)
【
data
】
— Trigger at the specified data bit, when measured signal data bits are effective
as five to eight bits, select the data, and select the trigger relationship as =, >, <, ≠, then
select the trigger data, press or roll the wheel to adjust, or press the data on the
touch screen, using the virtual keyboard to modify.
d)
【
0: data
】
—the measured signal data bits is nine. Only when the ninth bit is zero, then
trigger. The trigger relation, trigger data configuration and data, trigger simultaneously.
e)
【
1: data
】
—the measured signal data bits is nine. Only when the ninth bit is one, then
trigger. The trigger relation, trigger data configuration and data, trigger simultaneously.
f)
【
x: data
】
— the measured signal data bits is nine. Only when the ninth bits is X, then
trigger. The trigger relation, trigger data configuration and data, trigger simultaneously;
