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:TECHnology <ThresholdType>
Sets the threshold value of the UART line as defined for various signal technologies.
Parameters:
<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.
Parameters:
<ThresholdValue> Range: -400 to 400
Increment: 1E-3
*RST: 1.4
Default unit: V
BUS:SETReflevels
Sets the appropriate threshold or threshold for the selected serial protocol.
Usage:
Event
BUS:UART:STDBitrate <Bitrate>
Sets the number of transmitted bits per second.
