Accurate signal monitoring is critical for

designing quality products. In today’s

competitive environment, you need bet-

ter 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 harmonics, IMD,

and wide dynamic range measurements 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.

Precision Spectrum Analysis with Improved Speed and Accuracy

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.
