7 Save/Recall/Print
7.3 Save
Both single and double quotes are supported for any filename parameter over SCPI
The Recall dialog has only CSV as the file type. You cannot load MDF files back into the instrument
Dependencies For SA measurements, traces cannot be recalled from a trace file that was saved with all traces
selected
Couplings When you select which trace to save, it makes that trace the current trace, so it displays on top of all
the other traces
Preset Not part of Preset, but is reset to CSV by Restore Mode Defaults
Status Bits/OPC
dependencies
Sequential - waits for previous measurement to complete
Trace File Contents
Trace data files contain the data for one or all traces.
Metadata: Trace Specific
Besides the trace data, the file contains metadata describing the context by which
the trace was produced. Some of the metadata is trace specific:
–
Trace Type
–
Detector
–
Trace math (function, operand1, operand2, offset, reference)
–
Trace name/number
When importing a trace, the detector and/or trace math function specified in the
metadata is imported with the trace, so that the annotation correctly shows the
detector and/or math type that was used to generate the data
Metadata: Display Specific
The file also contains some display-related metadata:
–
Ref Level Offset
–
External Gain
–
X-Axis Unit
–
Y-Axis Unit
Metadata: Measurement Related
The rest of the metadata is measurement specific and reflects the state of the
measurement the last time the trace was updated. These are the “measurement-
related instrument settings” which, if changed, cause a measurement restart.
