Measurement Capabilities
Measured Parameters
S11, S22, S33, S44, S12, S13, S14, S21, S23, S24, S31, S32, S34, S41, S42, S43 and
absolute power of the reference and received signals at the port.
Number of Measurement Channels
Up to 16 independent logical channels : each logical channel is represented on the screen
as an individual channel window. A logical channel is defined by such stimulus signal settings
as frequency range, number of test points, or power level.
Data Traces
Up to 16 data traces can be displayed in each channel window. A data trace represents
one of such parameters of the DUT as S-parameters, response in time domain,
input power response.
Memory Traces
Each of the 16 data traces can be saved into memory for further comparison with
the current values.
Data Display Formats
Logarithmic magnitude, linear magnitude, phase, expanded phase, group delay, SWR,
real part, imaginary part, Smith chart diagram and plar diagram display formats are available.
Dynamic Rnage
Typical dynamic range of 150dB is achieved through the entire frequency range
(at 1Hz IF bandwidth)
Low Measurement Errors
this devices have a low vatiation between a large pool of manufactured instruments.
Low trace noise allows for particularly high-precision measurements.
Key Features
Mixer/Converter Measurements
Scalar Mixer /
Converter Measurements
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.
Vector Mixer /
Converter Measurements
The vector method allows the measurement of both the magnitude and phase of the
mixer transmission coefficient.
Vector Mixer / Converter Calibration
This method of calibration is applied for vector mixer measurements.
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.
Sweep Trigger
Trigger Modes : continuous, single, or hold.
Trigger Sources : internal, manual, external, bus
Sweep Features
Sweep Type
Linear frequency sweep, logarithmic frequecny sweep, and segment frequency sweep
occur when the stimulus power is a fixed value. Linear power sweep occurs when
frequency is a fixed value.
Measured Points Per Sweep
Set by the user from 2 to 500,001.
Segment Sweep Features
A frequency sweep within several independent user-defined segments. Frequency range,
number of sweep points, source power, and IF Bandwidth should be set for each segment.
Source power from -60dBm to +10dBm with resolution of 0.05dB. In frequency sweep
mode, the power slope can be set to up to 2dB/GHz for compensation of high frequency
attenuation in connection wires.
Sweep Trigger
Trigger Modes : continuous, single, or hold.
Trigger Sources : internal, manual, external, bus
Trace Functions
Trace Display
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.
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
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.
Data trace, memory trace, or simultaneous indication of data and memory traces.
Trace Math
Data trace modification by math operations:
addition, subtraction, multiplication or division of measured complex values and
memory data.
Automatic selection of scale division and reference level value allow the most effective
display of the trace.
Electrical Delay
Calibration plane moving to compensate for the delay in the test setup. Compensation
for electrical delay in a device under test (DUT) during measurements of deviation from
linear phase.
Phase Offset
Phase offset is defined in degrees.
Frequency Scan Segmentation
This VNA has a large frequency range with the option of frequency scan segmentation.
This allows optimal use of the device, for example, to realize the maximum dynamic
range while maintaining high measurement speed.
Power Scanning and
Compression Point Recognition
The power sweep feature turns compression point recognition, one of the most
fundamental and complex amplifier measurements, into a simple and accurate operation.
Balanced Measurements
Time Domain Measurements
This function enables evaluation of devices with balanced ports, for instance, differential
amplifiers or transformers, as pictured here.
Port Impedance Conversion
S-Parameter Conversion
The function of conversion of the S-parameters measured at 50 port into the values,
which could be determined if measured at a test port with arbitrary impedance.
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.
