SCPI commands:
Equalization filter state:
[:SOURce]:DM:INTernal:EQUalization:FILTer:STATe { OFF } | ON
[:SOURce]:DM:INTernal:EQUalization:FILTer:STATe?
Equalization filter selection:
[:SOURce]:DM:INTernal:EQUalization:FILTer:SELect "filename"
[:SOURce]:DM:INTernal:EQUalization:FILTer:SELect?
To add a real filter to the file system:
:MEMory:DATA:FIR "filename", [REAL,] osr, coeff1 [,coeff2 […,
coeffN]]
:MEMory:DATA:FIR? "filename"
To add complex filter to the file system:
:MEMory:DATA:FIR "filename", COMPlex, osr, hIRe0, hQIm0 [, hIRe1,
hQIm1 […, hIReN, hQImN]]
:MEMory:DATA:FIR? "filename"
To add I/Q symbol data to the file system:
:MEMory:DATA “WFM1:filename", <blockdata>

Opens a file catalog of FIR filters to select as the equalization filter. Equalization filters are
typically complex and must have an oversample ratio of 1. The filter must not have more than
256 taps (512 coefficients for a complex filter). The equalization filter operates at 125MHz, so
all equalization filters must be resampled to 125MHz prior to being placed in the MXG.
Enables the internal
equalization filter.
