Network/Spectrum Analyzers
4396B RF Network/Spectrum/Impedance
Analyzer
The 4396B provides excellent RF vector network, spectrum, and
optional impedance measurements for lab and production applica-
tions. When combined with a test set, the 4396B provides reflection
measurements, such as return loss, and SWR, and S-parameters.
Gain, phase, group delay, distortion, spurious, CN, and noise
measurements often required for evaluating components and cir-
cuits can be measured using one instrument. As a vector network
analyzer, the 4396B operates from 100 kHz to 1.8 GHz with 1 mHz
resolution and its integrated synthesized source provides –60 to +20
dBm of output power with 0.1 dB resolution. The dynamic magnitude
and phase accuracy are ±0.05 dB and ±0.3° so that it can accurately
measure gain and group delay flatness, which are becoming more
important in modern electronics systems.
As a spectrum analyzer, the 4396B operates from 2 Hz to 1.8 GHz
with resolution bandwidths (RBWs) spanning 1 Hz to 3 MHz in a
1-3-10 sequence. A fully-synthesized local oscillator allows stable
and accurate frequency analysis. Direct A/D conversion (no LOG
amplifier is used) results in ±1.0 dB overall level accuracy. Noise
sidebands fall below –105 dBc/Hz offset 10 kHz from carriers below
1 GHz, while sensitivity is –150 dBm/Hz at 10 MHz and –147
dBm/Hz at 1 GHz. In addition, with two independent display chan-
nels available, you can simultaneously view network and spectrum
(or transmission and reflection) characteristics of the device under
test in split-screen format. For example, an amplifier’s frequency
response (network measurement) and distortion (spectrum mea-
surement) can be shown at the same time.
Extremely Fast Spectrum Measurement
The 4396B features a stepped Fast Fourier Transform (FFT) digital-
signal-processing (DSP) technique for 20 to 100 times faster narrow-
band spectrum measurement than swept-tuned spectrum analyzers.
The stepped FFT is performed when the resolution bandwidth
(RBW) is set at 3 kHz or below. For example, with a 30 Hz RBW and
10 kHz span, the 4396B has a sweep time of 400 ms, while swept-
tuned spectrum analyzers take a few tens of seconds. The stepped
FFT can greatly improve the speeds of narrowband spectrum
measurement such as frequency tuning of a VCO or CN measurements.
Time-Gated Spectrum Analysis
With Option 4396B-1D6, the 4396B offers time-gated spectrum
analysis capability to capture and measure repetitive burst signals in
video, disk drives, communication equipment, and more. The mini-
mum gate length is 2
µ
sec so that even narrow-burst signals can be
analyzed.
Impedance Measurement Function and
RF Impedance Test Kit
A full-featured impedance measurement function (useful for quick-
check general-purpose impedance applications) can be added to the
4396B by adding Option 4396B-010 and the 43961A RF impedance
test kit. Covering from 100 kHz to 1.8 GHz, impedance parameters
|Z|,
, C, L, Q, D, and more, are directly measured and displayed.
The basic impedance accuracy (typical value) is 3%. The 43961A RF
impedance test kit is designed for the 4396B and is required to utilize
the features of Option 4396B-010. A 7 mm connector is mounted on
this kit for easy connection to an appropriate impedance test figure.
A wide variety of Agilent test fixtures can be used with the test kit,
including the surface-mount-device (SMD) fixtures.
