Chapter 11 Protocol Decoding RIGOL
MSO7000/DS7000 User Guide 11-37
➢ Export: If you select "Packets", you can export time and the
corresponding decoded data. 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.
6. Interpret the decoded FlexRay frame data
âš« TSS: transmission start sequence, displayed as a pink patch.
âš« Sync Frame: displayed as a pink patch.
âš« ID (Frame ID): expressed in Hex, displayed as a blue-green patch.
âš« PL (Payload Length): expressed in Hex, displayed as a dark blue patch.
âš« HCRC (Header Cyclic Redundancy Check): expressed in Hex, displayed as a
yellow-green patch. When CRC error occurs, it is displayed as a red patch.
âš« CYC (Cycle Number): expressed in Hex, displayed as a light blue patch.
âš« Data: Its display format is the same as that of the bus data (Hex, Dec, Bin,
or ASCII), displayed as a green patch.
âš« TCRC (Tail Cyclic Redundancy Check): expressed in Hex, displayed as a
yellow-green patch. When CRC errors occur, it is displayed as a red patch.
I2S Decoding (Option)
The oscilloscope samples the I2S signal and judges each data point as logic "1" or
logic "0" according to the preset threshold level. I2S decoding is required to specify
the serial clock, channel signal, and the data's source channel. You need to set
Alignment, WS Low, and other parameters.
In the decode setting menu, press Decode1 → Bus Type, then rotate the
