Recall
where <mode name> is the parameter used to select the mode with the INST:SEL command (for example, SA for the Spectrum Analyzer).Register 1 thru Register 5Selecting any one of these register keys causes the Traces and State from the specified Register to be recalled. Each of the register keys annotates whether it is empty or at what date and time it was last modified.
Key Path: Recall
Mode: SA
Remote Command: :MMEMory:LOAD:TRACe
TRACE1|TRACE2|TRACE3|TRACE4|TRACE5|TRACE6,<filename>
:MMEMory:LOAD:TRACe:REGister
TRACE1|TRACE2|TRACE3|TRACE4|TRACE5|TRACE6,<integer>
Example: MMEM:LOAD:TRAC TRACE2,"MyTraceFile.trace"
This loads the trace file data (on the default file directory path) into the
specified trace; if it is a "single trace" save file, that trace is loaded to trace 2,
andis set to be not updating.
:MMEM:LOAD:TRAC:REG TRACE1,2
restores the trace data in register 2 to Trace 1
Notes: When you perform the recall, the recalling Trace function must first verify the
file is recallable in this instrument by checking instrument software version
and model number, since it includes State. If everything matches, a full recall
proceeds by aborting the currently running measurement, and loading the state
from the saved state file to as close as possible to the context in which the save
occurred. You can open .trace files from any mode that supports them, so
recalling a Trace 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 and
the saved measurement of the mode becomes the newly active measurement,
and the data relevant to the measurement (if there is any) is recalled.
Once the state is loaded, the trace data must be loaded. The internal flags are
consulted to see which trace to load and the "To Trace" setting to see where to
load it. Trace data is always loaded with the specified trace set to View, so that
the data is visible and not updating(so as not to erase the recalled data). If the
file is an "all trace" file, all traces are loaded with the saved data(to the
original trace the data was saved from) and set to View. Traces whose data is
not loaded are restored to the update state that existed when they were saved.
After the Recall the analyzer exits the Recall menu and returns to the previous
menu.
Some modes and measurements do not have available all 6 traces. Phase
Noise mode command, for example, is: MMEMory:LOAD:TRACe
TRACE1|TRACE2|TRACE3,<filename>
