Agilent EXA Signal Analyzer

Frequency and Time

c. Resolution Bandwidth Accuracy can be observed at slower sweep times than auto-coupled conditions.

Normal sweep rates cause the shape of the RBW filter displayed on the analyzer screen to widen by
nominally 6

%. This widening declines to 0.6% nominal when the Swp Time Rules key is set to Accu-

racy instead of Normal. The true bandwidth, which determines the response to impulsive signals and
noise-like signals, is not affected by the sweep rate.

a. Analysis bandwidth is the instantaneous bandwidth available about a center frequency over which the

input signal can be digitized for further analysis or processing in the time, frequency, or modulation
domain.

b. Option B25 is standard for instruments ordered after May 1, 2011.
