ERRor}
ID
Description
 SYNCbreak: triggers on the last bit of the sync field.
 ID: triggers when the frames with the specified ID are found.
 DATA: triggers when the data that meet the preset conditions are found.
 IDData: triggers when the frames with the specified ID and data that meet the
preset conditions are both found.
 SLEep: triggers when the sleep frame is found.
 WAKeup: triggers when the wakeup frame is found.
 ERRor: triggers on the specified type of error frame.
Return Format
The query returns SYNC, ID, DATA, IDD, SLE, WAK, or ERR.
Example
:TRIGger:LIN:WHEN SYNCbreak /*Sets the trigger condition to SYNCbreak.*/
:TRIGger:LIN:WHEN? /*The query returns SYNC.*/
:TRIGger:LIN:LEVel

(-5 × VerticalScale - OFFSet) to
(7 × VerticalScale - OFFSet)
0 V
Remarks
For VerticalScale, refer to the :CHANnel<n>:SCALe command; for OFFSet, refer to
the :CHANnel<n>:OFFSet command.
Return
