Specifications describe the instrument’s warranted
performance after a half-hour warm-up and over
the temperature range of 25° ± 5° C, unless other­wise stated. Specifications for frequencies above
3 GHz do not apply to instruments with Option 075
(75-ohm impedance).

Supplemental characteristics are typical but non­warranted performance parameters. These are
denoted as “typical,” “nominal,” or “approximate.”

The measurement uncertainty curves and meas­urement port characteristics given for Agilent
Technologies 8753ES systems also apply to the
8753ES with Options 006 and 011 and the 85047A
test set (50-ohm), or the 8753ES Option 011 with
an 85046B test set (75-ohm).

Dynamic Range

System dynamic range is calculated as the differ­ence between the receiver noise floor and the
lesser of either the source maximum output or the
receiver maximum input level. System dynamic
range applies to transmission measurements only,
since reflection measurements are limited by
directivity.

Noise floor is specified as the mean of the noise
trace over frequency. Noise floor is measured with
the test ports terminated in loads, full two-port
error correction for the 8753ES and enhanced­response error correction for the 8753ET (with
16 averages used during isolation), 10 Hz IF band­width (BW), maximum test port power, and no
averaging during the measurement.

Measurement Uncertainty

Measurement uncertainty curves utilize a Root
Sum Square (RSS) model for the contribution of
random errors such as noise, typical connector
repeatabilities, and test set switching; this is
combined with a worst-case model for the contri­butions of dynamic accuracy and residual system­atic errors.

Curves show the worst-case magnitude and phase
uncertainty for reflection and transmission meas­urements, after a full two-port error correction for
the 8753ES and enhanced-response error correc­tion for the 8753ET (including isolation with an
averaging factor of 16) using the specified cal kit,
with 10 Hz IF bandwidth (BW) and no averaging.

Measurement Port Characteristics

Characteristics show the residual system uncer­tainties for uncorrected performance and after
accuracy enhancement using full two-port error
correction for the 8753ES and enhanced-response
error correction for the 8753ET. These character­istics apply for an environmental temperature of
25° ± 5° C, with less than 1° C deviation from the
calibration temperature. Agilent 8753ET Option
004 may degrade transmission source match
as much as 2 dB, resulting in up to 0.05 dB addi­tional uncertainty in transmission tracking.

Corrected performance indicates residual error
after calibration. It is determined by the quality
of calibration standards, system repeatability,
stability, and noise.

Uncorrected performance indicates intrinsic errors
without calibration correction applied. This is
related to the ultimate stability of a calibration.

Measurement

Number of display channels

Four display channels available.

Number of measurement channels

Two primary and two auxiliary measurement
channels available.

Measurement parameters

8753ET: Reflection, transmission, A, B, R, A/R,
B/R, A/B. Conversion to impedance or admittance.
8753ES: S11, S21, S12, S22, A, B, R, A/R, B/R, A/B.
Conversion to impedance or admittance.

Formats

Cartesian: log/linear magnitude, phase, group
delay, SWR, real and imaginary.

Smith chart: with log/linear amplitude and phase,
R + jX, G + jB, or real/imaginary markers.

Polar: with linear/log amplitude, phase, or real and
imaginary markers.

Data markers

Each display channel has five independent markers
that can be displayed simultaneously. Twenty inde­pendent markers can be displayed in 4-channel
display mode when markers are uncoupled.

Marker functions

Markers can be used in various functions: Marker
search (Mkr to max, Mkr to min, Mkr to target),
Mkr bandwidth with user-defined target values,
Mkr to start, Mkr to stop, Mkr to center, Mkr to
span, Mkr to reference, Mkr to delay, and trace sta­tistics (average value, standard deviation, and peak­to-peak deviation of the data trace between two
markers). The tracking function enables continuous
update of marker search values on each sweep.

Group Delay Characteristics

Aperture: selectable

Maximum aperture: 20% of frequency span
Minimum aperture: (freq. span) / (number of
points +1)

Range

The maximum delay is limited to measuring no
more than 180° of phase change within the mini­mum aperture. Range = 1/(2 x minimum aperture)

Accuracy

The following graph shows group-delay accuracy
at 1.3 GHz with type-N full two-port calibration
and 10-Hz IF bandwidth. Insertion loss is assumed
to be <2 dB and electrical length to be ten meters.

Source Control

Sweep limits

Set start/stop or center/span of the stimulus
parameter (frequency, power, time) directly
through the source control keys and the control
knob, the step keys or the data entry keyboard.

Sweep type

Set a linear or logarithmic sweep, an arbitrarily
defined frequency list, a power sweep or a CW
(single frequency) type of sweep.

Measured number of points per sweep

Linear frequency: choose 3, 11, 26, 51, 101, 201,
401, 801, or 1601 points.

Fast swept list

Define up to 30 different sub-sweep frequency
ranges in any combination of CW, center/span, or
start-stop sweep modes. Set test-port power levels
and IF bandwidth independently for each segment.

Sweep modes

Set a coupled channel sweep (same stimulus conditions
on both channels) or an uncoupled channel sweep.

Chop/alternate

Select whether to alternately or simultaneously
(chop) measure channels when in dual-channel
mode. Chop mode is faster, while alternate mode
optimizes dynamic range.

Sweep time

Set sweep time in seconds, minutes, or hours.

Automatic sweep time

Select auto sweep time by entering zero seconds
sweep time. The analyzer will sweep at the minimum
sweep time for any subsequently selected stimulus
conditions. Auto sweep time is the default condition.

Agilent 8753ET/ES Supplemental Characteristics

17

Sweep trigger

Set to either continuous, single, group sweep, or
external trigger. Set external trigger to take a com­plete sweep or to measure individual points in a
frequency, power or list sweep.

Power

Set source power from -20 to +5 dBm for the
8753ET1or from -85 to +10 dBm for the 8753ES2.
Power slope can be set in dBm/GHz.

Power Meter Calibration

Select continuous leveling or use a correction table
to modify source power. The correction table is
created with an initial single sweep. Make single or
multiple power meter readings at each frequency.

Data Accuracy Enhancement

Measurement calibration

Measurement calibration significantly reduces
measurement uncertainty due to errors caused
by system directivity, source and load match,
tracking, and crosstalk. Full two-port calibration
removes all the systematic errors to obtain the
most accurate measurements.

Calibration types available

• Frequency response

Simultaneous magnitude and phase correction
of frequency response errors for either reflec­tion or transmission measurements.

• Response and isolation

Compensates for frequency response and direc­tivity (reflection) or frequency response and
crosstalk errors.

• Enhanced response calibration

Corrects for frequency response and source
match for transmission measurements, and
provides one-port calibration for reflection
measurements.

• One-port calibration

Uses test set port 1 or port 2 to correct for
directivity, frequency response and source
match errors.

• Two-port calibration

Compensates for directivity, source match,
reflection frequency response, load match,
transmission frequency response and crosstalk
for an S-parameter test set. Crosstalk calibration
can be omitted. Available on 8753ES analyzers.

• TRL*/LRM* calibration

Compensates for directivity, reflection and
transmission frequency response, and crosstalk
in both the forward and reverse directions.

Especially suitable for calibrating non­coaxial environments, such as in test fixtures.
TRL*/LRM* is a special implementation of
TRL/LRM calibration, modified for the three­sampler receiver in the 8753ES. Available
on Agilent 8753ES analyzers.

Interpolated error correction

With any type of accuracy enhancement applied,
interpolated mode recalculates the error coeffi­cients when the test frequencies are changed. The
number of points can be increased or decreased
and the start/stop frequencies can be changed, but
the resulting frequency span must be a subset of
the original calibration frequency span. System
performance is not specified for measurements
with interpolated error correction applied.

Velocity factor

Enters the velocity factor to calculate equivalent
electrical length.

Reference plane extension

Redefine the plane-of-measurement reference to other
than port 1 or port 2 of the 8753ET and 8753ES.

Select default calibration kit

Select from a list of standard calibration kits or
choose a user-defined kit.

Data Averaging

IF bandwidth

The IF bandwidth is selectable from 6 kHz to 10 Hz.

Weighted sweep-to-sweep averaging

Averages vector data on each successive sweep.

Trace smoothing

Computes the moving average of adjacent data
points. Smoothing aperture defines the trace
width (number of points) to be averaged, and
ranges from 0.25% to 20% of the trace width.

Display Control

Display formats

Single-channel, dual-channel overlay (both traces
on one graticule), dual-channel split (each trace
on separate graticules), three-channel split (each
trace on separate graticules), three-channel overlay

or recalled via the SAVE/RECALL menu. Instrument
states include all control settings, active limit lines,
active list frequency tables, memory trace data,
active calibration coefficients, and custom display
titles. Storage is in nonvolatile memory.

Test sequences

Six measurement sequences can be stored or
recalled via the sequencing menu. Sequences may
also be recalled from Preset menu. Sequence reg­ister 6 is part of nonvolatile storage and is not
erased during a power cycle. If sequence 6 is titled
AUTO, it will be executed when power is turned on.

Disk drive

Data, instrument states, user graphics, data plots
and test sequences can be stored on internal floppy
disk in MS-DOS® or Agilent’s standard LIF formats.

Data Hardcopy

Data plotting

Hardcopy plots are automatically produced with
HP-GL compatible digital plotters. The 8753ET/ES
provides Centronics, RS-232C, and GPIB interfaces.

Data listings

Printouts of instrument data are directly produced
with a printer such as the HP DeskJet or LaserJet.
Select black & white or color print. For a list of
compatible printers, consult our printer compati­bility guide Web page at www.agilent.com/find/pcg

Configure plots

any externally generated CW signal. Receiver
inputs A and B will measure this same frequency
for comparison or tracking measurements.

Automatic: The input signal frequency is counted
and displayed.

Manual: Measures the input signal closest to the fre­quency specified by the user (within +0.5 to +5 MHz).

Tuned receiver

Tunes the receiver for a synthesized CW input
signal at a precisely specified frequency. The time
bases of the external RF source or sources must
be tied to the external reference input (rear panel
BNC). The built-in RF source is not used.

frequency above the receiver as required in a swept
RF/IF, fixed LO, mixer test.

Service menu

Select the desired service test, service diagnostic,
service or verification mode.

Test Sequences

Description

Create, edit, save, or recall a series of front-panel key­strokes to automate a measurement. Test sequences
may contain basic stimulus and measurement func­tions (frequency, power, parameter, format, scale)
advanced operations (time domain, limit testing,
display marker values) and basic logical branching
(IF limit test fails DO sequence 5 or GOSUB).

Storage

Test sequences can be stored internally to a disk
drive and can be loaded from a computer over the
GPIB interface. Sequence 6 is saved in nonvolatile
storage and can be used as an autostart routine
when titled AUTO.

General purpose input/output

Read or write bits to the output port to control
external devices such as part handlers. Eight
output and five input TTL lines are available on
the parallel port.

Other functions

PAUSE/continue, wait, title sequence, print
sequence, duplicate sequence, pause, and select.

Time-domain (Option 010)

With the time-domain option, data from transmis­sion or reflection measurements in the frequency
domain are converted to the time domain using
a Fourier transformation technique (chirp Z) and
presented on the display. The time-domain response
shows the measured parameter value versus time.
Markers may also be displayed in electrical length
(or physical length if the relative propagation veloc­ity is entered).

Time stimulus modes

Two types of time excitation stimulus waveforms
can be simulated during the transformations,
a step and an impulse.

• Low-pass step

This stimulus, similar to a traditional time­domain reflectometer (TDR) stimulus wave­form, is used to measure low-pass devices. The
frequency-domain data should extend from
DC (extrapolated value) to a higher value.

• Low-pass impulse

This stimulus is also used to measure low-pass
devices.

• Bandpass impulse

The bandpass impulse stimulates a pulsed RF
signal (with an impulse envelope) and is used
to measure the time-domain response of band­limited devices.

Windows

The windowing function can be used to modify
(filter) the frequency-domain data and thereby
reduce overshoot and ringing in the time-domain
response. Three types of windows are available:
minimum, normal, and maximum.

Gating

The gating function can be used to selectively
remove reflection or transmission time-domain
responses. In converting back to the frequency­domain the effects of the responses outside the
gate are removed.

Remote Programming

Interface

GPIB interface operates to IEEE 488-1978 and IEC
625 standards and IEEE 728-1982 recommended
practices.

Addressing

The 85046A/B S-parameter test sets provide the
capability to measure reflection and transmission
characteristics (including S-parameters) of two­port devices in either direction with a single
connection. The test sets are controlled from the
8753ES Option 011 and include a programmable
step attenuator. The frequency range of the 85046A
50-ohm test set is 300 kHz to 3 GHz. The 85046A
has precision 7-mm connectors. The frequency
range of the 85046B 75-ohm test set is 300 kHz to
2 GHz. The 85046B has 75-ohm type-N(f) connec­tors. Both connectors can be adapted to other inter­faces with the appropriate precision adapters.

A standard 85046A/B test set contains a solid­state transfer switch, which allows continuous
switching of power from port 1 to port 2 for full
two-port error correction. Option 009 replaces the
transfer switch with a mechanical switch. This
provides about 1.5 dB more power at the test port,
but does not allow continuous switching, so the
user must initiate updates of all four S-parameters
for full two-port error correction. Also, the mechan­ical switch has relays that will wear out faster
than the solid-state switch. Approximate lifetime
of the mechanical switch is 1 million cycles.

Agilent 85047A S-Parameter Test Set

The 85047A S-parameter test set provides the
capability to simultaneously measure the reflec­tion and transmission characteristics of two-port
devices in either direction with a single connec­tion. This test set includes a frequency doubler
that can be switched in by an 8753B/C Option 006
to measure 3 MHz to 6 GHz in a single sweep or
switched out to measure 300 kHz to 3 GHz in
a single sweep. The 8753ES Option 011 does not
use the frequency doubler, so the full 300 kHz to
6 GHz range is available. This test set exhibits
<5 dB insertion loss between the RF input and the
test ports for as high as 15 dBm at the test port,
and also includes a programmable step attenuator.
There are two rear panel BNC outputs. One pro­vides a TTL signal which indicates the result of
a limit test. The second TTL output is controlled
from the 8753ES test sequence function.

A standard 85047A test set contains a solid-state
transfer switch, which allows continuous switching
of power from port 1 to port 2 for full two-port
error correction. Option 009 replaces the transfer
switch with a mechanical switch. This provides
about 2.5 to 3.5 dB more power at the test port,
but does not allow continuous switching, so the
user must initiate updates of all four S-parameters
for full two-port error correction. Also, the mechan­ical switch has relays that will wear out faster
than the solid-state switch. Approximate lifetime
of the mechanical switch is 1 million cycles.

Agilent 8347A RF Amplifier

The 8347A RF amplifier delivers increased
power across a 300 kHz to 3 GHz frequency
range. The 8347A provides leveled output power
without using an external coupler and detector,
since these parts are built-in. The external ALC
can be directly connected to the external AM
input on the 8753ET/ES. This capability is espe­cially useful for achieving high dynamic range
measurements at faster sweep rates.

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 produc­tion 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 performance 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, out­of-warranty repairs, and on-site education and training, as well
as design, system integration, project management, and other
professional 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.
