Recall
More InformationIn 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.
Notes: When you pick a file to recall, the analyzer first verifies that the file is
recallable in the current instrument by checking the software version and
model number of the instrument. If everything 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.
Backwards Compatibility SCPI: :MMEMory:LOAD:STATe 1,<filename>
For backwards compatibility, the above syntax is supported. The "1" is
simply ignored.
