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 581 and "Trace
Display State (Remote Command Only)" on page 581, for details on the SCPI to control these two
variables.
Couplings 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.
