DEVice:INFO:HWBand?

Queries the frequency bands used for measurement by the R&S FSW hardware. The

start frequency of each band is provided.

The bands are instrument-specific and depend on the currently defined RBW, VBW

and YIG preselector state. The precise frequency bands are required to define correc-

tion data for the correct bands, in particular for frequency-drifting DUTs.

This query is only available in zero span mode.
