Equalizer Coefficients files have extension .csv. The default filename is
EqualizerCoef_0000.csv, where the 4-digit number is the lowest number that
does not conflict with any filename in the current directory.
See ".csv equalizer coefficient file format" on page 2414
Remote Command
:MMEMory:STORe:DDEMod:SEGMent1|…|6:EQUalizer:COEFficient <filename>
Example Save the equalizer’s coefficient data of segment1 to the file myEqualizerCoef2.csv in the
current path:
:MMEM:STOR:DDEM:SEGM1:EQU:COEF "myEqualizerCoef2.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
