Identifer Relation
Defines how the specified identifier pattern is compared with the acquired signal. The
instrument triggers if the acquired address is equal or unequal the defined pattern.
Remote command:
TRIGger:SENT:ICONdition on page 479
Sync Pulse Error
Detects a synchronization/calibration pulse error in transmission sequences of the fast
channel. An error occurs when:
●
The duration of the synchronization/calibration pulse (in ticks) is less than 56*(1-
clock tolerance) or more than 56*(1+clock tolerance).
●
The synchronization/calibration pulse duration of frame (n–1) varies by more than
1.5625% from the calibration/sync pulse duration of frame (n).
Remote command:
TRIGger:SENT:PULSeerror on page 480
Pulse Period Error
Detects an error in the calibration/sync pulse in transmission sequences of the fast
channel. An error occurs when a nibble has any of the following:
●
Number of ticks at low is fewer than 4 ticks.
●
Nibble value< 0 (fewer than 12 ticks) or > 15 (more than 27 ticks).
Through the pulse period error, you can also identify a nibble length error of the previ-
ous transmission sequence.
Remote command:
TRIGger:SENT:PPERioderror on page 480
Fast CRC Error
Detects a checksum error in the transmission sequences of the fast channel. The CRC
length is 4 bits.
Remote command:
TRIGger:SENT:FCRCerror on page 479
Slow CRC Error
Detects a checksum error in serial messages of the slow channel. The CRC length is 4
bits for short serial messages, and 6 bit of enhanced serial messages.
Remote command:
TRIGger:SENT:SCRCerror on page 480
Frame Length Error
Detects frame length errors in transmission sequences when Pause Pulse is set to
"Constant frame length".
A frame length error occurs, when the total length of the transmission sequence
(including pause pulse) does not match the Frame Length.
Remote command:
TRIGger:SENT:IRFLength on page 480
