HP 4395A repair Service and software
S.I. repairs the venerable Hewlett Packard (now
Agilent, Keysight) 4395A Network, impedance and spectrum analyzers.
HP (Agilent, Keysight) 4395A Key Points:
The 4395A provides excellent vector network, spectrum,
and optional impedance measurements for lab and production
applications. Gain, phase, group delay, distortion, spurious, CN, and
noise measurements often required for evaluating components and
circuits can be measured using one instrument.
When combined with a test set, the 4395A provides
reflection measurements, such as return loss, SWR, and S parameters. As
a vector network analyzer, the 4395A operates from 10 Hz to 500 MHz
with 1 mHz resolution; and its integrated synthesized source provides
-50 to + 15 dBm of output power with 0.1 dB resolution. The dynamic
magnitude and phase accuracy are +/-0.05 dB and +/-0.3 deg. so that it
can accurately measure gain and group delay flatness, which are
becoming more important in modern electronics systems.
a spectrum analyzer, the 4395A operates from 10 Hz to 500 MHz with
resolution bandwidths (RBWs) spanning 1 Hz to 1 MHz in a 1-3-10 steps.
A fully-synthesized local oscillator allows stable and accurate
frequency analysis. Direct A/D conversion (no LOG amplifier is used)
results in +/-0.8 dB level accuracy (@50 MHz, -20 dBm). Noise sidebands
fall below -100 dBc/Hz @ 100 kHz offset from carriers, while
sensitivity is -145 dBm/Hz at 10 MHz.
These analyzers were notorious
for having display problems and failed power supplies. We stock
refurbished display modules, power supplies, and all major boards and
We also occasionally have
complete refurbished units
available for sale. they are a great value for their
capabilities. The 4395A versions we sell for approximately
$18,700 (depending on
options and cosmetic condition) with warranty. Please email
us for availability.
