176User Manual 1317.4726.02 ─ 01
The UART protocol has no clock for synchronization. The receiver synchronizes by
means of the start and stop bits, and the bit rate that must be known to the receiver.
Trigger
The R&S RTM can trigger on specified parts of UART serial signals:
●
Start bit
●
Frame start
●
A specified symbol
●
Parity errors, and breaks
●
Frame errors
●
A serial pattern at any or a specified position
11.4.2 UART/RS-232 Configuration
11.4.2.1 Configuring UART/RS-232 Interfaces
To configure the UART interface, you assign the channels to the RX an (optionally) TX
lines, set the active state for each line and set some protocol-specific parameters.
1. Press the PROTOCOL LOGIC key on the front panel.
2. If the "Logic" menu is displayed, press "Protocol".
3. Press the "Bus Type" softkey and select "UART".
4. Press "Configuration".
5. Press "RX" and select the channel connected to the receiver line.
6. Press "TX" and select the channel connected to the transmitter line.
7. Set the "Active" state, "Parity" bit and the number of "Stop Bits".
8. Press "More".
9. Enter the "Symbol size".
10. Enter the bit rate:
● For a standard bit rate, select the "Defined Bit Rate".
● For a user-defined bit rate, press "User Bit Rate" and enter the value
11. Set the "Idle Time" between two frames.
