See: "More Information" on page 1744
Notes For the commands to control the two variables, Update and Display, see "Trace Update State On/Off"
on page 1743 and "Trace Display State On/Off" on page 1743 below
Dependencies When Signal ID is on, this key is grayed-out
Couplings Selecting a Trace Type for a trace (pressing the key or sending the equivalent command) puts the
trace in Active (Update ON and Display ON), even if that trace type was already selected
Selecting a detector for a trace (pressing the key or sending [:SENS]:DET:TRAC) puts the trace in
Active (UpdateON and DisplayON), even if that detector was already selected
Selecting a "Math Function" on page 1745 other than OFF for a trace (pressing the key or sending the
equivalent command) puts the trace in Active (UpdateON and DisplayON), even if that Math Mode 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
Trace Update State On/Off
Remote
Command
For Swept SA Measurement (in SA Mode):
:TRACe[1]|2|…|6:UPDate[:STATe] ON | OFF | 1 | 0
:TRACe[1]|2|…|6:UPDate[:STATe]?
For all other measurements:
:TRACe[1]|2|3:<meas>:UPDate[:STATe] ON | OFF | 1 | 0
:TRACe[1]|2|3:<meas>:UPDate[:STATe]?
where <meas> is the identifier for the current measurement
Example Make trace 2 inactive (stop updating):
:TRAC2:UPD 0
Couplings Whenever you set Update to ON for any trace, the Display is set to ON for that trace
Preset For Swept SA Measurement (in SA Mode):
1|0|0|0|0|0
ON for Trace 1; OFF for 2–6
For all other measurements:
1|0|0
ON for Trace 1; OFF for 2 &3
State Saved Saved in instrument state
Trace Display State On/Off

Command
For Swept SA Measurement (in SA Mode):
:TRACe[1]|2|…|6:DISPlay[:STATe] ON | OFF | 1 | 0
