Remote command:
CHANnel<m>:THReshold:FINDlevel
Parity
Defines the optional parity bit that is used for error detection.
"None"
No parity bit is used.
"Even"
The parity bit is set to "1" if the number of data bits set to "1" is odd.
Adding the parity bit makes the data word's parity even.
"Odd"
The parity bit is set to "1" if the number of data bits set to "1" is even.
Adding the parity bit makes the data word's parity odd.
Remote command:
Stop Bits
Sets the number of stop bits: 1 or 1.5 or 2 stop bits are possible.
Remote command:
Bit Rate
Sets the number of transmitted bits per second.
"Predefined"
Selects from a list of predefined bit rates between 300
Bit/s and
1
MBit/s.
"User"
Specifies an individual bit rate with values between 150 and
39,062,500.
Remote command:
Data Size
Sets the number of data bits of a word in a range from 5
bits to 9
bits.
Remote command:
Idle Time
Sets the minimal time between two data frames (packets), that is, between the last
stop bit and the start bit of the next frame.
Remote command:
UART / RS232 (option R&S
RTA-K2)
