WORD SYNC THRES LEVEL= d

SYNC

Analyzer only

Requires the 1-Mbit Option.

This function is used to set the BER synchronization threshold used by the Analyzer for long WORD patterns. This function does not affect the sync. thresholds for PRBS or short WORD patterns, which are fixed.

Long Word Synchronization Threshold Level (d): Set this parameter to a level from 1 to 9.

The long WORD synchronization threshold is always set to 256 errors in a rolling window of variable length. The length of this window is automatically set by the Analyzer, based on the selected threshold level, so that the nine threshold levels effectively correspond to the following bit error rates:

Level BER

13.1 E-02

27.8 E-03

31.9 E-04

49.7E-04

54.8 E-04

62.4 E-04

71.2 E-04

86.1 E-05

93.0 E-05

See an additional list of remote commands in the Appendix that support the 1-Mbit Programmable Word option.
