Accurate signal monitoring is critical
for designing quality products. In
today’s competitive environment, you
need better spectrum measurement
capabilities to stay ahead of the
competition. The Agilent 4395A/96B,
designed with new digital techniques,
outperforms traditional analog
spectrum analyzers.
• Improve testing speed up to 100
times for narrow RBW sweep. The
analyzer’s stepped FFT technique
(4395A: all RBWs, 4396B: RBW
≤ 3 kHz) breaks the speed barrier
to give you lower noise floor
without sacrificing speed.
• Fully synthesized source.
• 1 Hz RBW with 3:1 shape factor
for close-in signals.
List sweep function can be used in not
only network and impedance analysis,
but also in spectrum analysis. List
sweep separates the sweep frequency
range into segments, and each segment
can have an independent frequency
range, number of sweep points, RBW,
and power level settings. By using list
sweep function, separate frequency
bands can be measured in one sweep,
or different RBW can be set for harmon-
ics, IMD, and wide dynamic range meas-
urements can be done in a shorter time. • See close-in signals using the
1 Hz RBW with a 3:1 shape factor.
Monitor close-in low level signals such
as the 60-Hz power line sideband
ripple shown here. You get excellent
spectral resolution from digital RBW
filters (4395A: all RBWs, 4396B:
RBW
≤ 3 kHz) with a shape factor
as steep as 3:1.
Measure noise precisely. The analyzer’s low
noise floor provides the sensitivity required for
detecting low-level signals.

IMD measurement using list sweep function
Get dramatic speed improvement, with no
loss of accuracy, for narrow RBW sweeps.
In addition, low phase noise provides improved
signal resolution.
