Agilent 8753E Technical Specifications

The HP 8753E RF vector network analyzer provides
all the performance and productivity features to
simplify and speed your component measurements in the
30 kHz to 6 GHz frequency range. Its new processor
makes measurement and data-transfer speeds up to seven
times faster than the previous model. Overall throughput
is enhanced by new features such as simultaneous four
parameter display* and adapter-removal calibration. An
integrated, synthesized source provides up to 10 mW of
output power (100 mW for Option 011), 1 Hz frequency
resolution, and linear-frequency, log-frequency, list­frequency, CW, and power sweep types. Three tuned
receivers allow independent power measurements or
simultaneous ratio measurements over a wide dynamic
range of 105 dB at 6 GHz (with Option 006 frequency
extension) or 110 dB at 3 GHz (standard). The integrated
test set allows you to measure transmission and reflection
characteristics of a device to 6 GHz, without a frequency
doubler.

The HP 8753E network analyzer features two independent
measurement channels. You can choose to display any
combination of reflection and transmission parameters,
in magnitude, phase, group-delay, Smith-chart, polar, SWR,
or time-domain formats. Softkeys let you quickly access
measurement functions, and you can view results in over­lay or split-screen format on the LCD color display. A
VGA-compatible output has been added to drive larger
external monitors for optimum viewing.

HP 8753E maximizes versatility
and performance

• Frequency range from 30 kHz to 3 GHz, or
optionally 6 GHz.

• Built-in S-parameter test set provides complete
forward and reverse measurements, allowing you
to characterize your component with a single
connection.

• 50 and 75-ohm solutions.

• Superb accuracy. Comprehensive calibration
guarantees accurate measurements. TRL*/LRM*
make calibration in noncoaxial environments easier
and more convenient.

• Mixer testing. Quickly and easily characterize
frequency translating devices such as mixers.

• Add swept harmonic measurements. Characterize
amplifier parameters — gain, 1 dB compression,
match — and 2nd and 3rd harmonic distortion with
the same test setup.

• Built-in 3.5 inch floppy disk drive provides
convenient storage of instrument states and data.

• Parallel and serial ports provide interfaces to
popular printers and plotters. The parallel port
can also be used as a general I/O bus, with user
controllable TTL inputs and outputs. Users can
also connect a DIN keyboard to speed up entry of
titles, labels, or file names, and for remote front
panel operation.

Definitions and test conditions

This document provides two types of performance
information:

Specifications describe the instrument’s warranted perfor­mance over the temperature range of 23 ± 3° 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.”

Dynamic range

System dynamic range is the noise level relative to a
“through.” It is calculated as the difference between the
maximum receiver input level and the receiver’s noise
floor. 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. A signal at this level would have a signal/noise
power ratio of 3 dB. Noise floor is measured with the test
ports terminated in loads, full two-port error correction
(with 16 averages used during isolation), 10 Hz IF band­width (BW), maximum test port power, and no averaging
during the measurement.

Measurement uncertainty

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

Calibration is the process of measuring known standards
from a calibration kit to characterize a network analyzer’s
systematic (repeatable) errors.

Reflection measurement uncertainty is plotted as a
function of S

11

(reflection coefficient, linear). The curves

assume a one-port device (S

21=S12

=0).

Transmission measurement uncertainty is plotted as a
function of S

21

(transmission gain/loss) in dB from the
reference level. The curves assume that the device is
well-matched (S

11=S22

=0).

The reference level for HP 8753E measurements is
–10 dBm test port power.

Measurement port characteristics

Corrected (residual) indicates performance after error
correction (calibration). It is determined by the quality of
calibration standards and how well “known” they are, plus
system repeatability, stability, and noise.

Uncorrected (raw) indicates intrinsic performance
without error correction. This is related to the ultimate
stability of a calibration.

Organization of data

The information in this document is organized into the
following sections. All data is subject to change.

3. The HP 8753E source characteristics and measurement accuracy in this mode are dependent
on the stability of the external LO source. The RF source tracks the LO to maintain a stable IF
signal at the R channel receiver input. Degradation in accuracy is negligible when using an
HP 8642A/B or HP 8656B RF signal generator as the LO source.

4. See the HP 8753E descriptions and options for a functional description. Measurement accuracy
is dependent on the stability of the input signal.

, 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. Markers can indicate
data at actual data points or they can interpolate between
data points to allow the setting of a marker at an exact
frequency. Any one of the five markers can be the refer­ence marker for delta marker operation. Markers can be
coupled or uncoupled between display channels. Ten
independent markers can be displayed simultaneously
on a single measurement in dual channel 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 ➞ start, mkr ➞ stop,
mkr ➞ center, mkr ➞ span, mkr ➞ reference, mkr ➞ delay,
and trace statistics (average value, standard deviation, and
peak-to-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

Group delay is computed by measuring the phase change
within a specified frequency step (determined by the fre­quency span, and the number of points per sweep).

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, CW-delta F, 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 (alternate
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.
The analyzers default to chop mode.

Sweep time

Set sweep time in seconds, minutes or hours. Minimum
sweep time is dependent on number of data points per
sweep and selected IF bandwidth.

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.

Sweep trigger

Set to either continuous, hold, 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 (–85 to +10 dBm)

1

for HP 8753E. Power
slope can be set in dBm/GHz. Control the test port signal
by setting the internal attenuator of the test set over a
70-dB range. Power trip automatically reduces source
power to its minimum value when excessive signal levels
are incident on the receiver test-port. A caution message
is also displayed. (Source power range differs depending
on the selected options. Refer to the “Test-Port Output
Characteristics” section for the appropriate instrument
for more information.)

Power meter calibration

Description

Use a power meter to set leveled input or output power at
the device under test at a single point or an entire sweep.
With an HP 436A, 437B, 438A, or 441A power meter
connected, the Cal Sweep measures the actual test-port
power. After the calibration is enabled, the internal RF
source power is adjusted (within the range of –85 to +10
dBm) to achieve the selected power at the input of the
device under test rather than at the test port output.
HP-IB control of the power meter for normalization or
leveling is built-in. Logarithmic, linear, CW, and list
sweeps can be calibrated.

Update calibration

Select continuous leveling (requires a power splitter) by
measuring and updating source power on each sweep or
use a correction table (to modify source power), which is
created with an initial single sweep.

Number of readings

Make single or multiple power meter readings at each
frequency.

Data accuracy enhancement

Measurement calibration

Measurement calibration is the process through which
measurement uncertainty due to errors caused by system
directivity, source and load match, tracking, and crosstalk
are significantly reduced. A wide range of calibrations are
available for the HP 8753E. 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. Requires a short or open circuit
termination (reflection) or a through connection
(transmission).

• Response and isolation

Compensates for frequency response and directivity
(reflection) or frequency response and crosstalk errors.
Requires an open, short, and load circuit termination
(reflection) and a through connection and load termina­tion (transmission).

• One-port calibration

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

• 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 eliminated. Requires open,
short, and load terminations for both ports plus a through
connection.

• TRL*/LRM* calibration

Compensates for directivity, reflection and transmission
frequency response, and crosstalk in both the forward
and reverse directions. Especially suitable for calibrating
non-coaxial environments, such as in test fixtures.
Requires through, reflect, and line or match standards.
TRL*/LRM* is a special implementation of TRL/LRM
calibration, modified for the three-sampler receiver in
the HP 8753E.

• One-port, two-path calibration

A two-port cal for the one-port reflection/transmission test
sets. Provides a full two-port error corrected measurement
when the device under test is turned around and measured
in both directions.

13

HP 8753E supplemental characteristics, cont’d

• 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
equal to or less than the original calibration frequency
span. System performance is not specified for measure­ments with interpolated error correction applied.

• Set Z
o

Can redefine the characteristic impedance of a measure­ment to a value other than 50 or 75-ohms.

• 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 HP 8753E. A new reference
plane is defined in seconds of delay from the test set port
and ranges between ±1 second.

• Select default calibration kit

Select from a list of standard calibration kits: 7 mm,

3.5 mm (choose HP 85033C or 85033D), type-N 50 ohm,

and type-N 75 ohm. You can also define the standards (for
example open circuit capacitance coefficients, offset short
length, or fixed loads) of a user-defined kit.

• Data averaging

IF bandwidth:

The IF bandwidth is selectable from 6 kHz to 10 Hz
bandwidth to reduce the effective displayed noise
floor of the instrument.

Weighted sweep-to-sweep averaging:

Averages vector data on each successive sweep.
A(n) = S(n)/F + (1–1/F)*A(N–1) where A(n) is the
current average, S(n) is the current input signal and
F is the averaging factor. Averaging factors range
from 1 to 999.

• Trace smoothing

Similar to video filtering, this function computes the
moving average of adjacent data points. Advantageous in
reducing relatively small peak-to-peak noise values on
large broadband measured data. Smoothing aperture
defines the trace width (number of points) to be averaged,
and ranges from 0.25% to 20% of the trace width. This func­tion also sets the aperture for group delay measurements.

Display Control

Test sequences

Description

Create, edit, save or recall a series of front-panel key­strokes to automate a measurement. Each of the six
sequence registers can hold approximately 200 instruc­tions. Create or edit a sequence by selecting the sequence
menu and then simply performing the front-panel key­strokes that would normally be used to make a manual
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). Completed sequences
are then saved and can be executed when you are ready
to repeat the test.

Storage

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

Branching

devices such as part handlers. Eight output and five input
TTL lines are available on the parallel port of
the HP 8753E.

Other functions

PAUSE/continue, wait, title sequence, print sequence,
duplicate sequence, pause and select. Time Domain
(Option 010)

Time domain (Option 010)

Description

With the time domain option, data from transmission
or reflection measurements in the frequency domain is
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

• Standard stimulus

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

• External stimulus

The definition of other time excitation stimulus wave­forms can be accomplished using an external controller.

• Low pass step

This stimulus, similar to a traditional time domain 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, the upper
limit being defined by the test set used. The time domain
response shows the parameter value versus time (multiply
by the speed of light, c, to obtain electrical length or by c
and Vrel to obtain physical length). The step response is
typically used for reflection measurements only.

• Low pass impulse

This stimulus is also used to measure low pass devices.
The frequency domain data should extend from DC
(extrapolated value) to a higher value, the maximum
frequency determined by the test set. The time domain
response shows changes in the parameter value versus
time. The impulse response can be used for reflection
or transmission measurements.

• Bandpass impulse

The bandpass impulse stimulates a pulsed RF signal (with
an impulse envelope) and is used to measure the time
domain response of band-limited devices. The start and
stop frequencies are selectable by the user to any values
within the limits of the test set used. The bandpass time
domain response also shows changes in the parameter
values versus time. Bandpass time domain responses are
useful for both reflection and transmission measurements.

• Time domain range

The range over which the display is free of response repe­tition depends on the frequency span and the number of
points. Range, in nanoseconds, is determined by

• Range resolution

Range-resolution is how closely in time that a response
can be located.

Range-resolution = time span/(number of points –1)

• 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 frequency domain the effects of the
responses outside the gate are removed. The location and
span of the gate can be controlled by setting either the
center position and time span of the gate or by setting the
start and stop time of the gate.

HP 85046A/B S-parameter test sets

The HP 85046A/B S-parameter test sets provide the capa­bility to measure reflection and transmission characteris­tics (including S-parameters) of two-port devices in either
direction with a single connection. The test sets are
controlled from the HP 8753E Option 011 and include
a programmable step attenuator. The frequency range of
the HP 85046A 50-ohm test set is 300 kHz to 3 GHz. The
HP 85046A has precision 7-mm connectors. The frequency
range of the HP 85046B 75-ohm test set is 300 kHz to

A standard HP 85046A/B 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 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.

HP 85047A S-parameter test set

The HP 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
HP 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 HP 8753E 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
HP 8753E test sequence function.
