the acquisition data range, the trace will stop updating, and a trace indicator “DATA?” (which means
“Data is questionable relative to current setup.”) will be displayed at the top right of the graph
The query returns a name that corresponds to the reference type as follows:
String Returned Definition
AUTO
Auto
BRIS
Burst Rise Edge
BFAL
Burst Fall Edge
SWOR
Sync Pattern
OFF
Off
Couplings If the align reference is in Auto, the selected reference depends upon Burst Search state and Sync
Search state:
–
If the Sync Search is On, the reference is the start time of the founded sync pattern, no matter what
state of the Burst Search is; if there is no sync pattern found, the trace stops updating until the sync
pattern is found, and a message “Sync Error; Sync Pattern not found” is generated
–
If the Sync Search is Off and the Burst Search is On, the reference is the rise edge of the burst; if
there is no burst found, the trace stops updating until the burst is found, and a message “Burst Not
Found” is generated
–
If neither the Sync Search nor the Burst Search are On, the reference is the start time of the
acquisition, the Search Time trace is the same as the Raw Main Time trace in this case
If the align reference is in Off, the trace alignment will not apply, the Search Time trace will be the same
as the Raw Main Time trace
Preset
AUTO
State Saved Saved in instrument state
Offset
Specifies the time offset in seconds from the selected reference. It works with
Reference and Interval, determine the trace alignment region.
