BUS:UART:SOURce <Channel>
Selects the input channel of the UART line.
Parameter:
<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.
Parameter:
<Polarity> IDLLow | IDLHigh
*RST: IDLHigh
BUS:UART:TECHnology <ThresholdType>
Sets the threshold value of the UART line as defined for various signal technologies.
Parameter:
<ThresholdType> TTL | ECL | CMOS | USER
TTL
1.4 V
ECL
-1.3 V
CMOS
2.5 V
USER
Set a user-defined value using BUS:UART:THReshold.
*RST: TTL
BUS:UART:THReshold <ThresholdValue>
Sets an individual threshold value for digitization of signals if BUS:UART:TECHnology
is set to USER.
