Convenience, portability and
outstanding performance
The innovative designs of the
Agilent 53150 Series microwave
counters offer an uncluttered, featureladen front panel. These designs
present no-compromise performance
and quality in a surprisingly small,
light, battery operated product.
The convenience of a single
microwave input
The Agilent 53150 Series has an
advanced sampler that integrates a
separate zero bias Schottky diode for
the accurate measurement of input
power. This allows measurement of
both frequency and power with a
single connection. No compromise
in frequency coverage is required for
this capability. The ultrawideband
microwave input covers the entire
RF and microwave spectrum, from
intermediate frequencies IFs) of 50
MHz to millimeter waves.
The power measurement accuracy
and repeatability of these counters
rivals power meters with diode
sensors. Since frequency and power
of the input signal are measured
simultaneously, adjustment for the
diode’s frequency response is done
automatically. And like the latest in
diode sensors, compensation is also
made for deviation from square law.
Field tough but ready for
benchtop or ATE applications
The Agilent 53150 Series is as comfortable in the field as in the laboratory.
The rugged case with an integrated
tilting handle can tolerate the vibration
and shock expected in field use. The
backlit LCD display ensures visibility
in all environments, from dark to full
sunlight, at distances exceeding 15
feet.
If ac power is unavailable, the internal,
replaceable camcorder batteries provide at least 2.5 hours of continuous
operation. The unit can also be powered
from an external 11-18 Vdc source.
For benchtop and ATE applications,
the Agilent 53150 Series delivers full
functionality and high measurement
speed. The fully programmable
RS-232 interface and high speed
GPIB interface are standard features.
No compromise performance
The Agilent 53150 Series offers
exceptional sensitivity by utilizing a
single board design with low phase
noise PLL circuitry. Despite their
simple appearance, these counters
retain all the powerful functions one
expects in precision instrumentation:
measurement averaging, arbitrary
as well as nulling offsets for both
frequency and power, display of
power in either dBm or Watts.
Additional capabilities include full
control of resolution, sampling rate,
and GPIB address plus extensive
self-diagnostics, fast acquisition
times and full programmability.
Performance surpasses the industry
standard Agilent 5350 Series, in
virtually every aspect, in a package
less than half the weight and size.
