and "Payload". You can also tap "Packets", "Details", or "Payload" at
the top of the event table to select it.
If you select "Packets", the decoded data (TX and/or RX), time, and
error information (TX and/or RX) are displayed in the event table. If
you select "Details", the detailed data in the specified row will be
displayed in the event table. If "…" appears in the row of data, it
indicates that the decoded data are not fully displayed. At this time,
you can view the details in the "Packets" view. If you select "Payload",
all data in the specified column will be displayed in the event table. If
"…" appears in the specified column of data, it indicates that the
decoded data are not fully displayed. At this time, you can view the
details in the "Packets" view.
➢ Export: If you select "Packets", you can export time, the corresponding
decoded data, and etc. Press Export, the save setting menu is
displayed. You can export the data table of the packets to the internal
or external USB storage device (when detected) in CSV format. For
detailed saving operation, refer to descriptions in "Store and Load".
➢ Jump to: Set the operating status of the oscilloscope to "STOP". Then,
select the data of the specified time from the event table. Press Jump
to and the specified data waveforms are displayed in the center of the
screen.
➢ Decode: The setting of this menu enables you to quickly view the
corresponding event tables of four decode modules (Decode1,
Decode2, Decode3, and Decode4). Press Decode and rotate the
multifunction knob to select a decode module, then press down
the knob to select it. You can also press Decode continuously or
enable the touch screen to select it.
7． Error expressions in decoding
In RS232 decoding, parity error and/or EOF (end of frame) error may occur.
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 (00000100) 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.
