The Agilent Technologies 83599A
(10 MHz to 50 GHz) and 83598A
(2.4 GHz to 50 GHz) RF plug-ins for
the Agilent 8350B sweep oscillator
mainframe combine excellent performance and reliability in two broadband coaxial swept frequency sources.
These plug-ins feature high output
power (+10 dBm to 20 GHz, +3 dBm
to 40, and 0 dBm to 50 GHz), as well
as excellent harmonic performance
(<–45 dBc from 1.5 to 20 GHz, <–40 dBc
to 40 GHz, and <–35 dBc to 50 GHz).
For applications requiring additional
power to 20 GHz, these plug-ins also
provide a switch selectable high power
mode which boosts the RF output to
+15 dBm from 2.4 to 20 GHz.
50 GHz coaxial coverage
The 83599A and 83598A plug-ins
incorporate 2.4 mm connectors which
make high performance broadband
coaxial measurements possible. The
superiority of 2.4 mm connectors lies
in their ruggedness, repeatable performance, and excellent match over
the entire frequency range. 2.4 mm
connectors are also incorpoated into
other Agilent instrumentation and
devices so that a complete 10 MHz
to 50 GHz coaxial system can be
configured.

Unsurpassed versatility
With these additions, the 8350B
sweeper family offers a choice of
twenty Agilent 83500 series plug-ins.
The 8350B has a straightforward
front panel with easy-to-use knob,
step, and data entry keyboard controls. Almost all plug-in functions are
fully programmable via the Agilent
Interface Bus. Numerous features
such as power sweep, slope, alternate
sweep, save/recall registers, and five
independent markers emphasize the
8350B’s versatility.
Outstanding reliability
The 8350B mainframe and all 83500
series plug-ins are backed with a oneyear warranty on the instrument and
a two-year warranty on microcircuits.
These microcircuits are also established on our microcircuit exchange
program to further minimize the cost
of ownership. Option W30 on the
mainframe and plug-ins guarantees a
low cost of ownership by providing
two additional years of service at a
low price.
Applications
Scalar network analysis
Testing components up to 50 GHz in a
coaxial environment is now possible
with the 83599A and 83598A RF plugins. A broadband swept scalar measurement system is easy to configure
using these 50 GHz sweepers with the
Agilent 8757C/E scalar network analyzer and the appropriate 2.4 mm
scalar accessories.
Simultaneously measure a device’s
reflection and transmission characteristics by using the 85027D 10 MHz
to 50 GHz 2.4 mm directional bridge
to measure the reflected signal and
the 85025D 10 MHz to 50 GHz 2.4 mm
detector to measure the transmitted
signal. Improve measurement accuracy
by ratioing. Ratioing can be accomplished by adding an Agilent 11667C
10 MHz to 50 GHz 2.4 mm power
splitter and a second 85025D detector
to measure the reference signal.
The 8757C/E scalar network analyzer
can operate in either AC-detection
mode for reliable drift-free measurements or in DC-detection mode for
accurate swept power measurements.
Scalar measurement dynamic range is
maximized by the plug-ins’ excellent
harmonic performance, making them
an ideal choice for scalar network
analysis.
Local oscillator
The broadband frequency coverage
and high output power of the 83599A
and 83598A RF plug-ins make them
ideal as local oscillators for downconverting high frequency signals to a
lower intermediate frequency. These
plug-ins provide the broadest frequency
coverage for mixer measurements systems where a 50 GHz coaxial local
oscillator is required. Coaxial noise
figure measurements up to 50 GHz
are also possible using the Agilent
8970B noise figure meter with an
83599A or 83598A plug-in. In this
application, the plug-in is used to
downconvert the high frequency signals to the 10 to 1600 MHz range of
the noise figure meter.
Stand alone source
The outstanding performance of the
83599A and 83598A RF plug-ins make
them especially attractive as stand
alone sources for various signal generation and simulation applications.
In addition to their broad frequency
coverage, these plug-ins provide
greater than 45 dBc of harmonic and
subharmonic suppression from 1.5 to
20 GHz, greater than 40 dB to 40 GHz,
and greater than 35 dB to 50 GHz. They
also provide CW frequency accuracies
of better than ±5 to ±25 MHz depending on the frequency of operation.
These plug-ins have very flexible amplitude, frequency, and pulse modulation
capabilities. For example, ±75 MHz
deviations are possible for frequency
modulation rates of DC to 100 Hz. An
internal pulse modulator provides
calibrated leveled pulses with as narrow as 1.5 µ sec widths and 50 nsec
rise/fall times. Finally, both plug-ins
provide an optional 60 dB step attenuator which allows output power control from +10 to –72 dBm.
