• Byte Space (Byte Space)
The instrument displays data whose time length is less than the specified byte space (Byte Space) in a single
group.
Selectable Range
The selectable range is from the time length that corresponds to the number of bits in the UART signal data
format plus 2 bits, to 100 ms.
The “2 bits” that are added are the start and stop bits.
For example, if the data format is 8 bits with a parity bit, the time length is as follows:
Data (8) + parity bit (1) + start bit (1) + stop bit (1) = Time length for 11 bits
Resolution: 1 μs
Default value: Time length that corresponds to the number of bits in the UART signal data format and 2 bits

Level (Level) and Hysteresis (Hys)
These items are the same as those of the edge search.
Auto Setup (Auto Setup)
Executes auto setup based on the specified sources.
The auto setup feature automatically configures the bit rate, sample point, level, and hysteresis and then triggers
on the UART signal's Stop Bit. You cannot execute auto setup when:
• The sources is set to Math1 to Math4.
• State display is applied to a LOGIC bit that is set as the source.
Decoded Display (Decode)
The colors that are used for the fields in the decoded display are as follows:
Data Cyan (Cyan)
Parity Yellow (Yellow)
Start Bit Gray (Gray) fill
Stop Bit Gray (Gray) fill
Error Red (Red)
Framing Error:
Displays the words “Framing Error” in the field in which an error
occurred using black characters on red background. It is displayed
with higher precedence than a parity error.
Parity Error:
Displays the characters of the field in which an error occurred using
black characters on red background.
