Zero-Span RBW
Zero-Span RBW is the resolution bandwidth used when making the zero-span
intermod measurements when "Zero-Span Measurement" on page 1831 is ON. The
Zero-Span RBW is typically smaller than the main resolution bandwidth, although it
must still be large enough to accommodate three times the width of the
intermodulation products.
The required frequency accuracy of the lower and upper base frequencies increases
when Zero-Span RBW decreases. For this reason, frequency counting is used when
the lower and upper base frequencies are in auto mode. For optimum measurement
speed, set the lower and upper base frequencies explicitly.

Dwell Time
This is the sweep time used when making the zero-span intermod measurements
when "Zero-Span Measurement" on page 1831 is ON. Additional sweep time gives
better noise performance.
