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.
You want to recall all traces
EMI Receiver Mode Reference
matches, a full recall proceeds by aborting the currently running measurement, clearing any pending
operations, and then loading the State from the saved state file. You can open state files from any
mode, so recalling a State file switches to the mode that was active when the save occurred. After
switching to the mode of the saved state file, mode settings and data (if any for the mode) are loaded
with values from the saved file. The saved measurement of the mode becomes the newly active
measurement and the data relevant to the measurement (if there is any) is recalled.
If there is a mismatch between file version or model number or instrument version or model
number, the recall functiontries to recall as much as possible and returns a warning message. It
may limit settings that differ based on model number, licensing or version number.
After recalling the state, the Recall State function does the following:
• Makes the saved measurement for the mode the active measurement.
• Clears the input and output buffers.
• Status Byte is set to 0.
• 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.

For backwards compatibility, the above syntax is supported. The "1" is simply ignored.
Prior to A.02.00
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.
Save Trace+State from ALL traces.
9 Strip Chart Measurement
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.
On Recall, all traces will come
back in View (or Blank if they were
in Blank or Background when
saved)
