Word Synchronization Threshold (SYNC)
Format:
F1:ESC F4:SET
WORD SYNC THRES LEVEL= d
Menu: WORD
Function Name: SYNC
Instruments: Analyzer only
Options: Requires the 1-Mbit Option.
Application: 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.
Parameters: Long Word Synchronization Threshold Level (d): Set this
parameter to a level from 1 to 9.
Notes: 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
1 3.1 E-02
2 7.8 E-03
3 1.9 E-04
4 9.7E-04
5 4.8 E-04
6 2.4 E-04
7 1.2 E-04
8 6.1 E-05
9 3.0 E-05
See an additional list of remote commands in the Appendix that
support the 1-Mbit Programmable Word option.
