6 Series MSO option "6-SRAUDIO"
Audio (I2S, LJ, RJ, TDM) Bus (option 6-SRAUDIO):
Trigger on Word Select, Frame Sync, or Data. Maximum data rate for I2S/LJ/RJ is 12.5 Mb/s. Maximum data rate for TDM is 25 Mb/s
Serial protocol triggering and analysis (optional)
During debugging, it can be invaluable to trace the flow of activity through a system by observing the traffic on one or more serial buses. It could take many minutes to manually decode a single serial packet, much less the thousands of packets that may be present in a long acquisition.
And if you know the event of interest that you are attempting to capture occurs when a particular command is sent across a serial bus, wouldn't it be nice if you could trigger on that event? Unfortunately, it's not as easy as simply specifying an edge or a pulse width trigger.
The 6 Series MSO offers a robust set of tools for working with the most common serial buses found in embedded design including I2C, SPI, RS-232/422/485/UART, SPMI, CAN, CAN FD, LIN, FlexRay, SENT, USB LS/FS/HS, Ethernet 10/100, Audio (I2S/LJ/RJ/TDM), MIL-STD-1553, and ARINC 429. Serial protocol search enables you to search through a long acquisition of serial packets and find the ones that contain the specific packet content you specify. Each occurrence is highlighted by a search mark. Rapid navigation between marks is as simple as pressing the Previous ( ← ) and Next ( → ) buttons on the front panel or in the Search badge that appears in the Results Bar.
