Recall
•
Executes a *CLS
If the file specified is empty an error is generated. If the specified file does not exist, another error is
generated. If there is a mismatch between the file and the proper file type, an error is generated. If
there is a mismatch between file version or model number or instrument version or model number, a
warning is displayed. Then it returns to the State menu and File Open dialog goes away.
After the Recall, the analyzer exits the Recall menu and returns to the previous menu.

Compatibility SCPI :MMEMory:LOAD:STATe 1,<filename>
For backwards compatibility, the above syntax is supported. The "1" is simply ignored.

More Information
In measurements that support saving Traces, for example, Swept SA, the Trace data is saved along with
the State in the State file. When recalling the State, the Trace data is recalled as well. Traces are recalled
exactly as they were stored, including the writing mode and update and display modes. If a Trace was
updating and visible when the State was saved, it will come back updating and visible,and its data will be
rewritten right away. When you use State to save and recall traces, any trace whose data must be
preserved should be placed in View or Blank mode before saving.
The following table describes the Trace Save and Recall possibilities:
You want to recall state and one
trace’s data, leaving other traces
unaffected. Save Trace+State from 1 trace.
Make sure that no other traces are
updating (they should all be in View
or Blank mode) when the save is
performed. On Recall, specify the trace you
want to load the one trace’s data
into. This trace will load in View.
All other traces’ data will be
unaffected, although their trace
mode will be as it was when the
state save was performed.
You want to recall all traces Save Trace+State from ALL traces. On Recall, all traces will come
back in View (or Blank if they were
in Blank or Background when
saved)
You want all traces to load exactly
as they were when saved. Save State On recall, all traces’ mode and data
will be exactly as they were when
saved. Any traces that were
updating willhave their data
immediately overwritten.
From File…
When you press “From File”, the analyzer brings up a Windows dialog and a menu entitled “File Open.”
This menu allows you to navigate to the various fields in the Windows dialog without using a keyboard or
mouse. The Tab and Arrow keys can also be used for dialog navigation.
