For example, :TRIGger:UART:CONdition START /*Set the trigger condition to START*/ :TRIGger:UART:CONdition? /*The query returns START*/ :TRIGger:UART:BAUD For example, :TRIGger:UART:BAUd 4800 /*Set the baud rate to 4800*/ :TRIGger:UART:BAUd? /*he query returns 4800*/ TRIGger:UART:LEVel For example, :RIGger:UART:ALEVel 0.16 /*Set trigger level 160mV*/ :TRIGger:UART:ALEVel? /*The query returns 1.600000e-01*/ 89 / 136 Description STARt: When the UART start bit appears, trigger in the middle of the bit. STOP: When the UART stop bit appears, trigger in the middle of the bit. Regardless of the stop position 1, 1.5, 2 of the device under test, this machine is equipped with 1 bit for processing.
READ DATA: The normal reception of data is completed, and the received UART _ data and user-set data are equal to trigger at the stop bit. COM ERR: Data is triggered when an error occurs at the start of the check _ without stopping the bit. PARITY ERR: The data is received normally. Triggered at the stop bit when an _ error occurs in the parity of the data. Return format The query returns START | STOP | READ DATA | PARITY ERR | COM ERR _ _ _ Command format :TRIGger:UART:BAUD _ :TRIGger:UART:BAUD? Function description Set or query the baud rate triggered by the UART. The default unit is bps.
Parameter Name Type Range Default _ Discrete {110|300|600|1200|2400|4800|9600| 19200|38400|57600|115200| 230400|460800|USER} 9600 Return format The query returns an integer or USER. Command format :TRIGger:UART:LEVel :TRIGger:UART:LEVel? Function description Set or query the trigger level when the UART triggers. The unit is the same as the current amplitude unit. Parameter Name Type Range Default Integer (-5 × VerticalScale - OFFSet) to (5 × VerticalScale - OFFSet) 0 Description This setting command is valid only when the selected source is an analog channel. Return format The query returns the trigger level in scientific notation.
