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 581
Display State (Remote Command Only)" on page
variables.
Selecting a trace type (Clear Write, Trace Average, Max Hold, Min Hold) for a trace (pressing the key
or sending the equivalent remote command) puts the trace in Trace On (Update On and Display On),
even if that trace type was already selected.
Selecting a detector for a trace (pressing the key or sending a [:SENS]:DET:TRAC command) puts the
trace in Trace On (Update On and Display On), even if that detector was already selected.
Loading a trace from a file puts that trace in View regardless of the state it was in when it was saved;
as does being the target of a Copy or a participant in an Exchange.
When a View/ Blank selection is made, the menu returns to the previous menu.
