Serial Decode (Summary) Dialog Box
The Serial Decode dialog box is a summary page of which decoders are ON, and how they are set up. In addition,
there are shortcuts to Decode Setup and Search.
There are four independent decoders. A user can operate up to four at a single time, though the limitation may be
on the number of channels that can be accommodated at one time. Each of the 4 decoders can be configured to
different FlexRay busses or any combination of serial data busses such as I
2
C, SPI, UART, RS-232, CAN or LIN if
the appropriate options are installed. Practically speaking, if a user was decoding signals with a clock and data
line (and perhaps also a chip select or other third line), then two simultaneous decodes is the maximum number
using the LeCroy oscilloscope analog channels. Addition of the MS-250 or MS-500 Mixed Signal Oscilloscope
options allows usage of digital lines for trigger and decoding, which preserves analog channels for other uses.
Contact LeCroy for more information about this option.
The detail of the Serial Decode dialog box is described as follows:
Decoder # - There are four independent decoders, each can be set
up a different way for a different protocol.
Decode ON Checkbox – If checked, the decoder is turned ON and
set to decode (provided the protocol is correctly setup in the
Decode Setup dialog box).
Protocol – This pop-up dialog allows selection of a specific serial
protocol. If FlexRay is the only option installed on the oscilloscope,
it is the only choice; if additional options are installed they appear
on this dialog as well.
