Simplify your RF calibration system
The Fluke Calibration 96040A RF Reference
Source enables you to simplify your RF calibration system by replacing many of
the instruments and accessories that make up your current system. Its precision
signal level and attenuation, high signal purity and precision low distortion
modulation make this reference source superior to the general-purpose signal
generators that are often used to calibrate spectrum analyzers, modulation
meters, RF sensors, attenuators, and similar instruments. Its low phase noise
provides superior phase noise performance.
Unlike many RF calibration solutions, the
96040A is designed specifically for RF calibration, with a calibration-oriented
user interface that makes it easy to learn and use. The 96040A speeds up
calibration procedures, reduces opportunities for operator errors, and greatly
simplifies RF metrology. As the core of an RF and microwave calibration system,
the 96040A covers the majority of test points required for calibrating spectrum
analyzers of any frequency range.
Automated with MET/CAL® Plus Calibration
Management Software, the 96040A reduces complexity and calibration times,
dramatically improving efficiency and increasing capacity by 50 % or more over
manual methods.
Key benefits
·Covers a broad range of RF calibration workload
·Reduces the number of instruments and interconnections required for
your RF calibration system
·“What you set
is what you get” accurate signal delivery direct to the UUT input
·Integrated 50 MHz frequency counter eliminates need for an
additional instrument • Calibration-specific interface simplifies technician tasks
·Simplifies uncertainty calculations by delivering known signals
direct to the unit under test (UUT)
·Lowers RF system maintenance costs
·With automation, reduces spectrum analyzer calibration times by as
much as 50% over manual methods
Broad, versatile workload coverage
The 96040A calibrates a broad workload of
RF calibration devices, including:
·Spectrum analyzers
·Modulation meters and analyzers
·RF power meters and sensors
·Frequency counters
·Attenuators
·And more
The metrology associated with calibrating
these items becomes simpler because you have fewer error sources and
uncertainty contributions to consider.
More than just an RF calibrator
There are many applications in research and
development, manufacturing test, and ATE needing better performance than a
general purpose signal generator. If wide frequency coverage, frequency
resolution, low harmonics, phase noise and spurious content, signal level and
attenuation accuracy, or dynamic range are critical parameters the 96040A is an
ideal solution.
Cut the cost of your RF calibration system
in half
As the central instrument in a high
capability RF spectrum analyzer calibration system, the 96040A can cut your
costs in half. The 96040A replaces all of these parts of a “typical” RF
calibration system:
Up to four signal sources (from audio/
function generators to RF signal and low phase noise sources)
·Power meters and power sensors
·Step attenuators
·Filters
·Pads
·Couplers
·50 MHz frequency counter
The 96040A not only reduces the initial
need to purchase, install and configure RF system components, but it also
reduces the maintenance and calibration costs associated with all of that
equipment. The 96040A is also easier to transport than a heavy rack of
equipment and accessories, making it a good solution for on-site calibration.
With its 4 GHz frequency range, the 96040A
performs more than 80 % of all the tests required on high performance, high
frequency spectrum analyzers.
For workload items that require frequencies
beyond 4 GHz, you can use an RF and microwave source that you probably already
own alongside the 96040A to address the few remaining higher frequency test
points. For many spectrum analyzer models operating below 4 GHz, you only need
a 96040A to perform the entire calibration. You can’t simplify
much more than that!
No need for additional function generators
The 9640A Reference Source’s internal
modulation capability makes it suitable for applications that require precision
modulation to be applied to the output signal, such as modulation analyzer
calibration and spectrum analyzer sweep time testing using an AM signal with
more accurate modulation rates. You don’t need additional
function generators as a low frequency modulation source—the 96040A
delivers it all.
Designed for RF calibration
The 96040A user interface is designed to
simplify processes for calibrating typical items in your workload, such as
spectrum analyzers, RF level meters and receivers. Parameter offset, stepping,
relative and UUT/DUT error readout modes allow you to work accurately and
efficiently, following familiar calibration procedures. You’ll find it
easier than ever to determine the performance and tolerances of units under
test.
The 96040A front panel is equipped with
dedicated function keys, context-sensitive softkeys, and a bright, easy-to-read
color display that make it easy to learn and operate. You can set output levels
in terms of power (watts or dBm), voltage (RMS or peak to peak) using familiar
multipliers and exponent forms. You can move easily between voltage, power and
dBm units without losing entered values or accuracy. In error readout mode to
adjust the reading, simply rotate the spin wheel and the UUT error is displayed
directly in dB, ppm or percent.
The simple, calibration-oriented user
interface also makes troubleshooting easier if you encounter an unexpected
result or an out-of-tolerance condition while following a manual or automated
calibration procedure.
“What you set is what you get” accuracy and signal
purity
A rugged, precise levelling head delivers
96040A signal levels directly to the unit under test (UUT) input just the way
you set them on the front panel. This unique “What you set is what
you get” feature helps you avoid problems like losses, noise, interference,
and mismatch errors, which can be caused by using intermediate connectors and cables.
This approach also maintains the integrity of low-level signals. The head
maintains signal precision and noise immunity throughout a 154 dB dynamic
range, down to the very lowest levels at -130 dBm.
The leveling head reduces lead changes from
25 to just 5 during a typical calibration, allowing you to “connect once
and test many,” extending unattended times in an automated system, and reducing
connector wear.

Calibrated as a system to assure system
performance
The 96040A is supplied with a 50 ohm
leveling head. The /75 model has both 50 ohm and 75 ohm leveling heads. Each
mainframe and head are calibrated together as a complete system. System
calibration helps assure overall system performance. Each 96040A instrument is
supplied with a comprehensive ISO 17025 compliant certificate of calibration
with data for all key parameters, including level and attenuation, output VSWR,
and phase noise. You can be assured that your 96040A is traceable, plus RF
metrology and uncertainty analysis become much simpler and faster. Accredited
certification is available for the 96040A and both 50 ohm and 75 ohm heads.
State-of-the-art phase noise performance
With reduced low phase noise optimized for
low and high offset frequencies and specifications from 1 Hz to 10 MHz offsets,
the 96040A offers exceptional phase noise performance beyond that required for
today’s high performance workloads.
Phase noise data is included in the 96040A
certificate of calibration. Instead of relying only on the more conservative
guaranteed specifications, users have actual performance data for their unit.
Even with the best low phase noise signal generators, filters are commonly used
during spectrum analyzer phase noise calibration tests, reducing noise levels
at wide (high) offset frequencies to improve test margins. The 9600FLT 1 GHz
bandpass filter accessory is designed specifically for high performance
spectrum analyzer wide-offset phase noise testing and connects easily to 96040A
models in either benchtop or rack-mounted applications.
Selectable frequency reference input/
output expands functionality
Selectable external frequency reference
input is available as a standard feature on the rear panel of the 96040A. The
input allows you to lock the frequency output to an external reference, such as
the Fluke Calibration 910R Rubidium Standard, for applications where high clock
accuracy or use of a common reference frequency is important. The frequency
reference output allows a UUT to be frequency locked to the 96040A internal
reference clock. This configuration is often required to reduce frequency
offset errors that may occur between the reference source and the UUT.
Simplify frequency response tests with
96040A sweep functions
RF applications often require a frequency
sweep. The 96040A’s sweep functions simplify the application of manual legacy spectrum
analyzer frequency response testing, as well as filter response measurements.
Automate with MET/CAL® software for “walk-away” efficiency
In a typical automated RF calibration
process, the operator must frequently intervene to change test setups, thus
limiting the benefits that can be realized by the automation. Walk-away
automation can increase calibration system capacity by up to 25 percent using
procedures you develop in MET/CAL Plus Calibration Management Software. For
example, the manufacturer’s calibration procedure for calibrating the Agilent E4407B 26.5 GHz
spectrum analyzer requires 27 different and complex test setups. On the other
hand, the 96040A, used with MET/CAL Plus Calibration Management Software, can
perform the major core of required tests with a single setup. Only six
additional setups would be needed using a MET/CAL procedure.
MET/CAL procedures created by Fluke
Calibration for the 9640A models can be used by the 96040A in 9640A emulation
mode. Optimized automated procedures can save time for the operators by
allowing them to leave the system running while attending to other work. For
example, the E4407B MET/CAL procedure for the legacy 9640A, running in
emulation mode on the 96040A, allows for a total 90 minutes of “walkaway” time within
the total two-hour calibration runtime.
Using the 96040A with other automation
solutions
The 96040A is also integrated easily into
existing automated systems and software. The time savings and efficiency gains
offered by the 96040A can be realized by structuring test sequences to take
full advantage of its “connect once measure many” capabilities.
The 96040A is designed to match or exceed
the performance and functionality of the HP333** and HP8662/3A in calibration
systems. With HP333** and HP8662/3A GPIB command emulation as standard,
replacing these popular but obsolete and difficult-to-maintain products becomes
just a plug-and-play substitution.
