31 :SBUS<n> Commands

:SBUS<n>:NRZ:TRIGger

(see page 1610)

Command Syntax

:SBUS<n>:NRZ:TRIGger <mode>

<mode> ::= {SOF | VALue}

The :SBUS<n>:NRZ:TRIGger command specifies the trigger mode:

• SOF (Start Of Frame) — triggers at the start of a NRZ frame, before the header

field.

• VALue — triggers on the specified bit values (see

:SBUS<n>:NRZ:TRIGger:PATTern:VALue:WIDTh and

:SBUS<n>:NRZ:TRIGger:PATTern:VALue:DATA), up to 128 bits, after the

specified number of starting bits.

Note that the trigger value is always for bits as they arrive (that is, MSB first).

When the decode bit order (see :SBUS<n>:NRZ:BITorder) is MSBFirst, the

decoded value bit order matches the trigger value bit order.

When the serial decode bit order is LSBFirst, the decoded value bit order is

opposite of the trigger value bit order.

Query Syntax

:SBUS<n>:NRZ:TRIGger?

The :SBUS<n>:NRZ:TRIGger? query returns returns the trigger mode setting.

Return Format

<mode> ::= {SOF | VAL}
