:SBUS<n>:SENT:TRIGger
(see page 1428)
Command Syntax
:SBUS<n>:SENT:TRIGger <mode>
<mode> ::= {SFCMessage | SSCMessage | FCData | SCMid | SCData
| TOLerror | FCCerror | SCCerror | CRCerror | PPERror | SSPerror}
The :SBUS<n>:SENT:TRIGger command specifies the SENT trigger mode:
• SFCMessage — triggers on the start of any Fast Channel Message (after 56
Synchronization/Calibration ticks).
• SSCMessage — trigger on the start of any Slow Channel Message.
• FCData — triggers on a Fast Channel Message when the Status &
Communication nibble and the data nibbles match the values entered using
additional softkeys.
• SCMid — triggers when a Slow Channel Message ID matches the value entered
using additional softkeys.
• SCData — triggers when a Slow Channel Message ID and Data field both match
the values entered using additional softkeys.
• TOLerror — triggers when the sync pulse width varies from the nominal value by
greater than the entered percentage.
• FCCerror — triggers on any Fast Channel Message CRC error.
• SCCerror — triggers on any Slow Channel Message CRC error.
• CRCerror — triggers on any CRC error, Fast or Slow.
• PPERror — triggers if a nibble is either too wide or too narrow (for example, data
nibble < 12 (11.5) or > 27 (27.5) ticks wide). Sync, S&C, data, or checksum
pulse periods are checked.
• SSPerror — triggers on a sync pulse whose width varies from the previous sync
pulse's width by greater than 1/64 (1.5625%, as defined in the SENT
specification).
