Hi Ivan,
The ‘jumps’ you are seeing are due to different calibration settings being applied to the individual IF paths. Each IF is 20MHz wide and each IF has its own set of corrections. For the TG sweeps we did not optimize the bands for overall flatness, as once you store thru the correction differences are stored in the offset and the trace should be flat. Your measurements will not be affected as long as the store through has been performed.
