Description:
The FS-2000 family of frequency synthesizers
operate in the frequency of 1 MHz to 18.4 GHz
and offer submicrosecond frequency switch-
ing speed, and submicrosecond level correction,
coupled with superb spectral purity. With
an installed base supporting hundreds of
submicrosecond switching and high spectral
purity applications, the FS-2000 family are prov-
en performers for a diverse range of stringent
applications. Introduced in 1986, FS-2000
frequency synthesizers incorporate the most
significant advances in frequency synthesizer technology
and are based on Aeroflex’s patented wideband direct
analog synthesis techniques. The technology has been
constantly refined and enhanced so that today the family
comprises more than thirty models and a host of options
which assure that your application has a reliable, proven,
signal source.
Aeroflex’s FS-2000 is the most significant advance in
Frequency Synthesizer technology in over 10 years. It is the
first synthesizer to combine ultra fast switching, low phase
noise, and low spurious over a wide frequency range.
Aeroflex’s patented method achieves direct analog synthesis
over an octave range. This combined with extensive hybrid-
ization enables the FS-2000 to be packaged in 1/3 the size
of previous synthesizers. In addition, built-in fault isolation
and modular construction reduce MTTR
(Mean Time to Repair).
Interchangeability
and commonality of boards and modules
minimize spare parts requirements. FS-2000 fre-
quency synthesizers have uncompromising perform-
ance. Switching speed is specified simply; less than
1 usecond between any two frequencies with any
resolution- no ifs, ands, or buts. Close-in spectral purity is
virtually that of the frequency reference, multiplied to the
output frequency, while far-out noise decreases monoton-
ically to the floor. No phase-locked loops, no complicated
schemes.
Just simple, direct and reliable. The FS-2000 is based
on an iterative, modular direct analog architecture with a
central reference generator that synthesizes 50, 100,
150, 200 and 800 MHz signals from a 100 MHz refer-
ence derived by multiplying a 5 or 10 MHz reference
oscillator appropriately and improving far-out noise by
judicious filtering. All frequencies are derived in an iterative
frequency generation architecture. Frequencies are
generated as a decade of frequency steps over an octave
from 500 MHz inputs to the next stage.
Final outputs are produced by a scaling mod-
ule which provides for doubling, dividing, or hetero-
dyning to achieve a range of 10 MHz to 2.3 GHz.
Units which have extended frequency ranges use an
additional scaling module which doubles to 4.6 GHz,
and again to 9.2 and 18.4 GHz. The architecture
also provides the additional benefit of simplifying the
user interface programming in Binary Coded Decimal
(BCD). Naturally, a variety of interfaces are optionally
provided, including IEEE-488 and a user friendly keyboard.
This unique, interactive, modular architecture also allows
for easy configurations of OEM or specialized products.
