- this key toggles to select a Flat Top or a Gaussian (the
RBW Filter
default filter) resolution bandwidth filter. A Gaussian filter
provides more even time domain response, particularly for bursts.
A Flat Top filter provides a flatter bandwidth but is less accurate
for pulse responses. A Flat Top filter also requires less memory
and allows longer data acquisition times.

Troubleshooting Hints

Low output power can lead to poor coverage and intermittent service
for phone users. Out of specification power measurements indicate a
fault usually in the power amplifier circuitry. They can also provide
early indication of a fault with the power supply, i.e. the battery in the
case of mobile stations.
