Chapter 11 Protocol Decoding RIGOL
DS8000-R User Guide 11-11
âš« Parity Error
When a parity error is detected during the decoding, red error report
information will be displayed. For example, when "none" is chosen for the
parity on the transmitter and "odd" is chosen for the parity on the decoder,
the following parity error information
(its display form is related to the
value of the horizontal time base) occurs. Wherein, the number of 1s in the
8-digit figure (01001111) is an odd number, and the parity bit should be 0.
However, the parity bit detected on the Tx is 1; thus a parity error occurs.
âš« EOF Error
This error is generated when the EOF condition is not met. For example, if
the Stop Bit is set to 1.5, but the actual stop bits is less than 1.5 bits, then
the red error report information
(its display form is related to the value
of the horizontal time base) is displayed in the following figure.
âš« Parity Error and EOF Error
When both the parity error and the EOF error are detected, the error report
information (its display form is related to the value of the horizontal time
base), as shown in the following figure, will be displayed.
