:SENS1:SYNC:TYPE?

Either sets or gets the synchronization type. The synchronization type defines which patterns will be used to synchronize when a synchronization loss is detected by the Error Detector.

Parameter	Synchronization behavior

AUTO	The Error Detector will use all available
	patterns to synchronize with the incoming
	data stream.
SFP	The Error Detector will use only the
	pattern that is set for the SFP output.
SMA	The Error Detector will only use the
	pattern that is set for the SMA output.
PRBS7	The Error Detector will only use a PRBS
	2^7-1 data stream.
PRBS15	The Error Detector will only use a PRBS
	2^15-1 data stream.
PRBS23	The Error Detector will only use a PRBS
	2^23-1 data stream.
PRBS31	The Error Detector will only use a PRBS
	2^31-1 data stream.

Actual Bit Error Rate

:SENS1:FETC:ERAT:DELT

Syntax :SENS1:FETC:ERAT:DELT?

Description Gets the bit error ratio of the last update interval (approx 200ms).

Actual Number of Errors

:SENS1:FETC:ECO:DELT

Syntax :SENS1:FETC:ECO:DELT?

Description Gets the number of errors that have been counted during the last update interval (approx. 200ms).
