BUS:UART:SOURce <Channel>
Selects the input channel of the UART line.
Parameters:
<Channel> C1 | C2 | C3 | C4 | D0 | D1 | D2 | D3 | D4 | D5 | D6 | D7
C3 and C4: only R&S RTH1004
Digital channels are available if option R&S RTH-B1 is installed.
*RST: C1
BUS:UART:POLarity
<Polarity>
Defines the logic states of the line. In idle high state, the idle state corresponds to a
logic 1, and the start bit to a logic 0. In idle low state, the idle state corresponds to a
logic 0, and the start bit to a logic 1. During idle time, no data is transmitted.
Parameters:
<Polarity> IDLLow | IDLHigh
*RST: IDLHigh
BUS:UART:THReshold <ThresUserValue>
Sets the threshold value for digitization of signals. If the signal value is higher than the
threshold, the signal state is high. Otherwise, the signal state is considered low.
Parameters:
<ThresUserValue> Range: -8 to 8
Increment: 1E-3
*RST: 1.4
Default unit: V
BUS:UART:STDBitrate <Bitrate>
Sets the number of transmitted bits per second.
