This key lets you set the state of the two trace variables, Update and Display. The four choices available in
this 1-of-N menu are:
• Trace On: Update and Display both On
• View: Update Off and Display On
• Blank: Update Off and Display Off
• Background: Update On, Display Off (this allows a trace to be blanked and continue to update “in the
background”)
Key Path
Trace/Detector
Notes The four states of this 1-of-N actually set two variables, Update and Display, to their four possible
combinations:
Trace On: Update and Display both On
View: Update Off and Display On
Blank: Update Off and Display Off
Background: Update On, Display Off
See the following tables, "Trace Update State (Remote Command Only)" on page 1010 and "Trace
Display State (Remote Command Only)" on page 1010, for details on the SCPI to control these two
variables.
Couplings Loading a trace from a file puts that trace in View regardless of the state it was in when it was saved.
