Frequency-Dependent Offset
The frequency-dependent offset (FDO) feature provides you with a convenient way
to store the offset values in a handy table. Multiple FDO tables can be created to
compensate different external test setups with different frequency responses. By
turning on the FDO table during measurement, the pre-entered offset values will
be retrieved to compensate your external test setup over a range of frequencies.
The following programming sequence example describes the simplest commands
used to create a FDO table, assign an offset at a frequency value, store the table
under your preferred name, and turn on the table for measurement use.
-> MEM:TABL:SEL “CUSTOM_A” // Selects an FDO table named
“CUSTOM_A”.
-> MEM:TABL:FREQ 50MHz // Enters the frequency of 50 MHz into
the selected table.
-> MEM:TABL:GAIN 50 // Enters the reference offset factor of
50% into the selected table.
-> CORR:CSET2 “CUSTOM_A” // Enters the name of the selected
table.
-> CORR:CSET2:STAT 1 // Enables the selected table.
-> FREQ 1000MHz // Sets the frequency to 1000 MHz.
-> FETC? // Queries the measurement results.
