Before any Agilent Technologies’ signal
generator is introduced, specifications are
set to assure that the product will perform
consistently for your application. The
specification setting process is reflective
of the quality that Agilent has always
strived to deliver. An explanation of Agilent’s
specification setting process will show the
confidence that you can have when
selecting an Agilent Technologies
signal generator.

The model used for specification setting is
illustrated in the above right figure. The
following text defines each element in
the figure.

• Production margin is the difference
between the average product perform­ance and the Test Line Limit (TLL). This
TLL is the pass/fail limit used by the
production line at final test under
standard environmental conditions.

• Delta environmental represents the
possible change in performance over
the environmental extremes (e.g.,
temperature and humidity).

Average TLL SPEC

• Drift represents the change in perform­ance over the calibration period.

• Measurement uncertainty accounts for
possible measurement errors in the
equipment used to characterize the
signal generator.

• Customer guardband represents any
additional margin necessary to ensure a
worst case scenario.

This process means that whether the signal
generator is placed in a high temperature
environment such as at the top of a rack of
equipment or a well controlled environment,
the performance stated in our specifications
can be relied on for your most exacting
applications. This process guarantees that
the signal generator is introducing the
minimum error possible in the measure­ments you are performing.

(warranted)

Typical performance

Since some applications push the limits
of specifications, Agilent Technologies
also provides data that indicates typical
performance. This typical performance is
generally set at the Test Line Limit (TLL),
which is significantly better than the war­ranted specification. Use the typical data
when comparing different products, or when
your application pushes the limit on a given
specification. The following information
highlights typical performance for the
most common areas of interest for the
8643A, 8644B, 8664A and 8665A/B.

SSB phase noise

SSB phase noise is an important specifica­tion of a signal generator if it is to be used
for measuring the adjacent channel selec­tivity of a receiver. If the phase noise of the
signal generator is too high at frequency
offsets equal to the channel spacing, the
test results might indicate a failure of the
receiver when it is actually functioning
properly. For a receiver with <90 dB of
selectivity the 8643A is recommended. If
the selectivity is ≥90 dB, the 8644B (or
8664A with Option 004, or 8665A/B
Option 004) is recommended.

Output level accuracy

Output level accuracy is a combination of
temperature variation, flatness over fre­quency, and the signal generator’s internal
attenuator and detector accuracies. The
graph represents worst case output level
accuracy of a sampling of 8665Bs. All of
these units fall within the shaded area.

RF leakage

Due to radios becoming more sensitive
and operating at higher frequencies, the
traditional two-turn loop measurement of
RF leakage has become inadequate. To
overcome the shortcomings of the two­turn loop, Agilent has developed a new
measurement technique using resonant
dipole antennas, which is 20-25 dB more
sensitive than the two-turn loop method.
Agilent has been able to reduce the level
of radiated emissions in its newer signal
generators through innovative design and
packaging. Understanding that not all
applications require the lowest possible
emissions, Option 010 is available on all of
these performance signal generators.

Features that improve the usability of Agilent’s 8643A, 8644B, 8664A
and 8665A/B for your application!

Internal modulation source

• Low distortion sinewaves to 400 kHz
with variable phase and amplitude.

• Triangle, sawtooth and squarewaves to
50 kHz with variable phase and amplitude.

• White Gaussian noise with variable
amplitude.

• Two independent sources for two-tone
testing.

Optional pulse modulation
(Option 008, 8664A and
8665A/B)

• An Agilent designed GaAs pulse
modulator provides the exceptional
performance that is so critical for pulsed
applications.

• <5 ns rise/fall times, >80 dB on/off
ratio.

• Built-in pulse generator features
include variable pulse delay and width
from 50 ns to 999 ms. This saves
purchasing additional equipment.

• Leveled RF output maintains accuracy
while in pulse modulation.

High reliability electronic
attenuator on the 8643A
(optional on 8644B)

For applications up to 1 GHz, the electronic
attenuator used in the 8643A provides
increased reliability. Instead of using
mechanical relays, the electronic attenuator
uses solid-state components for setting
output levels accurate to within ±1.0 dB.
The Agilent patented design uses PIN
switching elements with three million
hours of MTBF, giving the attenuator an
estimated 0.2% failure rate.

Wideband FM (8664A and
8665A/B)

Performance signal generator
series features

2 GHz frequency counter
(Option 011, 8643A and 8644B)

• Typical rates to 5 MHz with 2 MHz of
deviation, or rates to 800 kHz with
10 MHz of deviation (fc>1500 MHz)
allows testing of most wideband
receivers.

• Excellent FM linearity is inherent due to
YIG oscillator design.

• Stable dc-coupled FM for measurements
that require low carrier drift.

• High stability oven controlled timebase
is standard.

• Surface mount construction for
improved reliability.

• Three year calibration cycle (MTBC)
means less time in the calibration lab.

• Built-in self-diagnostics and calibration
saves valuable time by significantly
reducing down time.

• 20 Hz to 2 GHz frequency counting via
front panel connector.

• Cost and space efficient solution for
applications involving audio frequency
measurements, local oscillator, IF and
transmitter testing.

• Eliminates the need to externally couple
the timebase references when using an
external counter.

Your Advantage

Your Advantage means that Agilent offers a
wide range of additional expert test and meas­urement services, which you can purchase
according to your unique technical and busi­ness needs. Solve problems efficiently and gain
