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.
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. Crosstalk calibration can be
omitted.
Mixer Calibration
Scalar-mixer calibration:
Scalar-mixer calibration corrects the conversion loss
for input port source match, output port load match,
absolute input or source power, and absolute output or
receiver power. Scalar-mixer calibrations also corrects
the input match measurements (S11) for input port
directivity, frequency response and source match at
the input frequencies and corrects the output match
measurement (S22) for output directivity, frequency
response and source match at the output frequencies.
Vector-mixer calibration:
At the input frequencies of the mixer, the vector-mixer
calibration compensates for directivity, source match,
and reflection frequency response. At the output
frequencies of the mixer, the vector-mixer calibration
compensates for directivity, load match, and reflection
frequency response. Frequency-translated transmission
response is compensated by using a characterized
calibration mixer. The characterization of the
calibration mixer is part of the calibration process.
TRL/TRM calibration
Compensates for directivity, reflection and transmission
frequency response and crosstalk in both forward and
reverse directions. Provides the highest accuracy for both
coaxial and non-coaxial environments, such as on-wafer
probing, in-fixture or waveguide measurements.
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
range must be within the original calibration frequency.
System performance is not specified for measurements
with interpolated error correction applied.
Velocity factor
Enters the velocity factor to calculate the equivalent
electrical length.
Reference plane extension
Redefine the plane-of-measurement reference to other
than port 1 or port 2.
Storage
Internal hard disk drive
Store and recall binary instrument states and calibra-
tion data on 10 GB, minimum, internal hard drive.
Instrument data can also be saved in ASCII (includ-
ing S2P) format. All files are MS-DOS®-compatible.
Instrument states include all control settings,
active limit lines, active list frequency tables,
memory trace data.
Data hardcopy
Printouts of instrument data are directly produced
on any printer with the appropriate Windows® 2000
printer driver. The analyzer provides USB, Centronics
(parallel), serial and LAN interfaces.
