Agilent Technologies’ Test and Measurement
Support, Services, and Assistance
Agilent Technologies aims to maximize the
value you receive, while minimizing your risk and
problems. We strive to ensure that you get the test
and measurement capabilities you paid for and
obtain the support you need. Our extensive support
resources and services can help you choose the
right Agilent products for your applications and
apply them successfully. Every instrument and
system we sell has a global warranty. Support is
available for at least five years beyond the produc-
tion life of the product. Two concepts underlie
Agilent's overall support policy: “Our Promise”
and “Your Advantage.”
Our Promise
Our Promise means your Agilent test and
measurement equipment will meet its advertised
performance and functionality. When you are
choosing new equipment, we will help you with
product information, including realistic perform-
ance specifications and practical recommendations
from experienced test engineers. When you use
Agilent equipment, we can verify that it works
properly, help with product operation, and provide
basic measurement assistance for the use of
specified capabilities, at no extra cost upon
request. Many self-help tools are available.
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 a competitive edge
by contracting with us for calibration, extra-cost
upgrades, out-of-warranty repairs, and on-site
education and training, as well as design, system
integration, project management, and other profes-
sional engineering services. Experienced Agilent
engineers and technicians worldwide can help
you maximize your productivity, optimize the return
on investment of your Agilent instruments and
systems, and obtain dependable measurement
accuracy for the life of those products.

Pulse sync out (A series only) Outputs a synchronizing pulse, nominally 50 ns
width, during internal and triggered pulse
modulation. TTL-level compatible, nominal
source impedance 50
Ω.
Rear panel connectors
(All connectors are BNC female
unless otherwise noted.)
Serial interface Used for serial communication
(9-pin RS-232 connector female).
GPIB Allows communication with compatible devices.
LAN Allows LAN communication
10 MHz input Accepts an external reference (timebase) input (at
1, 2, 2.5, 5, 10 MHz for standard and 10 MHz only
for option UNJ) Nominal input impedance 50
Ω.
Damage levels > +10 dBm
10 MHz output Outputs internal or external reference signal.
Nominal output impedance 50
Ω.
Nominal output power +4 dBm
Sweep output Generates output voltage, 0 to +10 V when signal
generator is sweeping. Output impedance < 1
Ω,
can drive 2000 Ω.
Trigger output Outputs a TTL signal: high at start of dwell, or
when waiting for point trigger in manual sweep
mode; low when dwell is over or point trigger is
received, high or low 4 us pulse at start of LF sweep.
Trigger input Accepts TTL signal for triggering point-to-point in
manual sweep mode, or to trigger start of LF
sweep. Damage levels
≥ +10 V or ≤ –4 V.
Source module interface Provides bias, flatness correction, and leveling
connections to the model 83550 Series mm-wave
source modules.
Source settled output Provides an output trigger that indicates when the
signal generator has settled to a new frequency or
power level (open-collector output).
EFC > 0.25 ppm for -5 to +5 V
Recommended calibration cycle 24 months
