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.

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.
