BW/Avg
For applications that require 6 dB resolution bandwidths, it is possible to use
NOTE
an equivalent 3 dB resolution bandwidth. Because the analyzer has Guassian
RBW, the equivalent 6 dB bandwidth of any RBW filter can be determined
using the following formula: 6 dB RBW = 3 dB RBW x 1.414. For example, if a
6 dB RBW of 100 kHz is required, the equivalent 3 dB RBW Filter would be
100 kHz/1.414 = 70.7 kHz. The closest RBW filter for the analyzer that would
be used is 68 kHz.
