How are RF offsets compensated for using the Agilent TS-5500 System?

In the Agilent TS-5550 system, RF offsets are automatically compensated for by the software. You store an array of offsets vs. frequencies for each RF path in a special FixtureCalibration symbol table. Whenever an Agilent-supplied RF measurement- or stimulus-related action is executed, the measurement or generator output will be automatically compensated based on the stored data.
