7 Save/Recall/Print
7.3 Save
For backwards compatibility, older limit files with the extension .lim can be read
into the instrument, but you can only save limits as .csv files.
Remote Command
:MMEMory:STORe:LIMit LLINE1 | … | LLINE6,<filename>
Example Save the 2nd Limit Line to the file myLimitLine2.csv in the current path:
:MMEM:STOR:LIM LLINE2,"myLimitLine2.csv"
Notes If the save is initiated via SCPI, and the file already exists, the file will be overwritten
Using the C: drive is strongly discouraged, since it runs the risk of being overwritten during an
instrument software upgrade
Both single and double quotes are supported for any filename parameter over SCPI
Dependencies Only appears if you have the proper option installed in your instrument
In the Log Plot measurement in Phase Noise Mode, there are only three Limit Lines, so the valid
parameters are LLINE1 | LLINE2 | LLINE3
Preset 1
Not part of Preset, but reset by Restore Mode Defaults
Survives power cycles
State Saved The selected Limit number is saved in instrument state
Status Bits/OPC
dependencies
Sequential - waits for previous measurement to complete
Limit File Contents
Limits may be exported into a data file with a .csv extension. They may be imported
from that data file; they may also be imported from a legacy limit file with a .lim
extension. The .lim files meet the specification for limit files contained in the EMI
measurement guide, HP E7415A.
.csv file format
Except for information in quotes, limit line files are not case sensitive. Information in
bold is required verbatim; other text is example text, and italic text is commentary
which should not be present in the file.
The first five lines are system-required header lines, and must be in the correct
order:
The next few lines describe the parameters; on export they will be in the order
shown, on import they can be in any order. If some parameters are missing, they will
revert to the default.
