Resolution Bandwidth (RBW)
Range (
−3.01 dB bandwidth)
1 Hz to 8 MHz
Bandwidths above 3 MHz are 4, 5,
6, and 8 MHz.
Bandwidths 1 Hz to 3 MHz are
spaced at 10
% spacing using the
E24 series (24 per decade): 1.0, 1.1,
1.2, 1.3, 1.5, 1.6, 1.8, 2.0, 2.2, 2.4,
2.7, 3.0, 3.3, 3.6, 3.9, 4.3, 4.7, 5.1,
5.6, 6.2, 6.8, 7.5, 8.2, 9.1 in each
decade.

a. The noise marker, band power marker, channel power and ACP all compute their results using the
power bandwidth of the RBW used for the measurement. Power bandwidth accuracy is the power
uncertainty in the results of these measurements due only to bandwidth-related errors. (The analyzer
knows this power bandwidth for each RBW with greater accuracy than the RBW width itself, and can
therefore achieve lower errors.) The warranted specifications shown apply to the Gaussian RBW filters
used in swept and zero span analysis. There are four different kinds of filters used in the spectrum ana-
lyzer: Swept Gaussian, Swept Flattop, FFT Gaussian and FFT Flattop. While the warranted perfor-
mance only applies to the swept Gaussian filters, because only they are kept under statistical process
control, the other filters nominally have the same performance.
b. The ratio of the noise bandwidth (also known as the power bandwidth) to the RBW has the nominal
value and tolerance shown. The RBW can also be annotated by its noise bandwidth instead of this 3 dB
bandwidth. The accuracy of this annotated value is similar to that shown in the power bandwidth
accuracy specification.
