the Lister.
Label values are always displayed in octal, and SSM and SDI values are
always displayed in binary.
3 Press the Word Format softkey and specify the word decode format:
• Label/SDI/Data/SSM:
• Label - 8 bits.
• SDI - 2 bits.
• Data - 19 bits.
• SSM - 2 bits.
• Label/Data/SSM:
• Label - 8 bits.
• Data - 21 bits.

to turn it on.

that the oscilloscope is AutoTriggering. Press the [Mode/Coupling] key, then press the
