Mixer/Converter Measurements
Scalar mixer / converter measurements
S5048 NETWORK ANALYZER 20 kHz-4.8 GHz
+23dBm RF 35V DC Max Avoid Static Discharge CAT I
Mixer Under Test
The scalar method allows the user to measure only the
magnitude of the transmission coefficient of the mixer and
other frequency translating devices. No external mixers
or other devices are required. The scalar method employs
port frequency offset when there is a difference between
the source port frequency and the receiver port frequency.
Scalar mixer / converter calibration
This is the most accurate method of calibration applied
for measurements of mixers in frequency offset mode.
The OPEN, SHORT, and LOAD calibration standards
are used. An external power meter should be connected
to the USB port directly or via USB/GPIB adapter.

Vector mixer / converter measurements*
The vector method allows the measurement of both the
magnitude and phase of the mixer transmission coefficient.
This method requires an external mixer and an LO common
for both the external mixer and the mixer under test.
Vector mixer /converter calibration*
G
This method of calibration is applied for vector
mixer measurements. OPEN, SHORT and
LOAD calibration standards are used.
Automatic frequency offset adjustment
The function performs automatic frequency offset
adjustment when the scalar mixer / converter
measurements are performed to compensate for
internal LO setting inaccuracy in the DUT.
*Only available in the S5048 configuration of this VNA.

Time Domain Measurements
This function performs data transformation from
frequency domain into response of the DUT to various
stimulus types in time domain. Modeled stimulus types:
bandpass, lowpass impulse, and lowpass step. Time
domain span is set by the user arbitrarily from zero to
maximum, which is determined by the frequency step.
Windows of various forms are used for better tradeoff
between resolution and level of spurious sidelobes.
Here, built-in time domain analysis
allows the user to detect a physical
impairment in the antenna feeder.
Time domain analysis allows
measurement of parameters of SAW
filters such as the signal time delay,
feedthrough signal suppression.

5048 VNA | Data Sheet
Time Domain Gating
This function mathematically removes unwanted responses
in the time domain, which allows the user to obtain
frequency response without influence from fixture elements.
This function applies reverse transformation back to the
frequency domain after cutting out the user-defined span in
time domain. Gating filter types: bandpass or notch. For a
better tradeoff between gate resolution and level of spurious
sidelobes the following filter shapes are available:
maximum, wide, normal and minimum.
Applications of these features include, but are not limited to:
measurement of SAW filter parameters, such as filter
time delay or forward transmission attenuation.
Limit Testing
Limit testing is a function of automatic pass/fail judgment
for the trace of the measurement results. The judgment is
based on the comparison of the trace to the limit line set
by the user and can consist of one or several segments.
Each segment checks the measurement value for
failing either the upper or lower limit, or both. The
limit line segment is defined by specifying the
coordinates of the beginning (X0, Y0) and the end
(X1, Y1) of the segment, and type of the limit. The
MAX or MIN limit types check if the trace falls
outside of the upper or lower limit, respectively.

Embedding
This function allows the user to mathematically simulate
DUT parameters by virtually integrating a fixture circuit
between the calibration plane and the DUT. This circuit
should be described by an S-parameter matrix
in a Touchstone file.
De-Embedding
This function allows the user to mathematically
exclude the effect of the fixture circuit connected
between the calibration plane and the DUT from the
measurement results. This circuit should be described
by an S-parameter matrix in a Touchstone file.

Port Impedance Conversion
This function converts the S-parameters measured at
the 50 port into values, which could be determined
if measured at a test port with arbitrary impedance.
S-Parameter Conversion
The function allows conversion of the measured
S-parameters to the following parameters: reflection
impedance and admittance, transmission impedance
and admittance, and inverse S-parameters.

Data Output
Analyzer State
All state, calibration and measurement data can be saved to
an Analyzer state file on the hard disk and later uploaded
back into the software program. The following four types of
saving are available: State, State & Cal, Stat & Trace, or All.
Channel State
A channel state can be saved into the Analyzer memory.
The channel state saving procedure is similar to saving of
the Analyzer state saving, and the same saving types are
applied to the channel state saving. Unlike the Analyzer
state, the channel state is saved into the Analyzer inner
volatile memory (not to the hard disk) and is cleared
when the power to the Analyzer is turned off. For
channel state storage, there are four memory registers
A, B, C, D. The channel state saving allows the user to
easily copy the settings of one channel to another one.
Trace Data CSV File
The Analyzer allows the use to save an individual trace data
as a CSV file (comma separated values). The active trace
stimulus and response values in current format are saved
to *.CSV file. Only one trace data are saved to the file.
Trace Data Touchstone File
The Analyzer allows the user to save S-parameters to
a Touchstone file. The Touchstone file contains the
frequency values and S-parameters. The files of this format
are typical for most of circuit simulator programs.
The *.s2p files are used for saving all the
four S-parameters of a 2-port device.
The *.s1p files are used for saving S11 and
S22 parameters of a 1-port device.
Only one (active) trace data are saved to the file.
The Touchstone file saving function is
applied to individual active channels.

Screenshot capture
The print function is provided with the preview feature,
which allows the user to view the image to be printed
on the screen, and/or save it to a file. Screenshots can be
printed using three different applications: MS Word, Image
Viewer for Windows, or the Print Wizard of the Analyzer.
Each screenshot can be printed in color, grayscale,
black and white, or inverted for visibility or ink use.
The current date and time can be added to each capture
before it is transferred to the printing application,
resulting in quick and easy test reporting.
Measurement Automation
COM/DCOM compatible
5048 software is COM/DCOM compatible, which allows
the unit to be used as a part of an ATE station and other
special applications. COM/DCOM automation is used for
remote control and data exchange with the user software.
The Analyzer program runs as COM/DCOM server.
The user program runs as COM/DCOM client. The
COM client runs on Analyzer PC. The DCOM client
runs on a separate PC connected via LAN.
LabView compatible
The device and its software are fully compatible with
LabView applications, for ultimate flexibility in
user-generated programming and automation.

Accuracy Enhancement
Calibration
TRL calibration*
Calibration of a test setup (which includes
the VNA, cables, and adapters) significantly
increases the accuracy of measure-ments.
Calibration allows for correction of the errors
caused by imperfections in the measurement
system: system directivity, source and
load match, tracking and isolation.
Method of calibration performed for full
S-parameter matrix measurement of a twoport DUT. It ensures higher accuracy than twoport calibration. LRL and LRM modifications
of this calibration method are available.
Calibration methods
The following calibration methods of
various sophistication and accuracy
enhancement level are available:
reflection and transmission normalization
full one-port calibration
one-path two-port calibration
full two-port calibration*
Reflection and transmission
normalization
This is the simplest calibration method;
however, it provides reasonably low
accuracy compared to other methods.
Full one-port calibration
Method of calibration performed for
one-port reflection measurements.
It ensures high accuracy.
One-path two-port calibration
Method of calibration performed for
reflection and one-way transmission
measurements, for example for measuring
S11 and S21 only. It ensures high accuracy
for reflection measure-ments, and mean
accuracy for transmission measurements.
Full two-port calibration*
This method of calibration is performed for
full S-parameter matrix measurement of a
two-port DUT, ensuring high accuracy.
*Only available in the S5048 configuration of this VNA.

Mechanical Calibration Kits
The user can select one of the predefined
calibration kits of various manufacturers
or define own calibration kits.
Automatic Calibration Modules (ACMs)
Electronic, or automatic, calibration
modules offered by CMT make the
analyzer calibration faster and easier than
traditional mechanical calibration.
Sliding load calibration standard
The use of sliding load calibration standard
allows significant increase in calibration
accuracy at high frequencies compared
to the fixed load calibration standard.
“Unknown” Thru calibration standard*
The use of a generic two-port reciprocal circuit
instead of a Thru in full two-port calibration
allows the user to calibrate the VNA for
measurement of "non-insertable" devices.
Defining of calibration standards
Different methods of calibration
standard defining are available:
standard defining by polynomial model
standard defining by data (S-parameters)
Error correction interpolation
When the user changes any settings such as
the start/stop frequencies and number of sweep
points, compared to the settings at the moment
of calibration, interpolation or extrapolation
of the calibration coefficients will be applied.
5048 VNA | Data Sheet
Supplemental Calibration Methods
Power calibration
Power calibration allows more stable maintainance of the power level setting at the DUT
input. An external power meter should be connected to the USB port directly
or via USB/GPIB adapter.
Receiver calibration
This method calibrates the receiver gain at the absolute signal power measurement.
