Storage
Removable hard disk drive Store and recall instrument states, calibration data, and trace data
on 3 GB, minimum, removable hard drive. Trace data can be saved in CSV
(comma separated value) format. All files are MS-DOS ® -compatible.
Instrument states include all control settings, limit lines, segment sweep
tables, and memory trace data.
File sharing Internal hard disk drive (D:) can be accessed from an external
Windows ® PC through LAN.
Disk drive Instrument states, calibration data, and trace data can be stored on
an internal 3.5 inch 1.4 MB floppy disk in MS-DOS ® -compatible format.
Screen hardcopy Printouts of instrument data are directly produced on a printer. The analyzer
provides USB and parallel interfaces.
1 Option E5070B-008 or E5071B-008 is required.
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 2-port, 3-port, or 4-port calibration
removes all the systematic errors for the related test ports to obtain
the most accurate measurements.
Calibration types available
Response Simultaneous magnitude and phase correction of frequency response
errors for either reflection or transmission measurements.
Response and isolation Compensates for frequency response and crosstalk errors of
transmission measurements.
Enhanced response Compensates for frequency response and source-match errors
One-port calibration Available on test set port 1, port 2, port 3, or port 4 to correct for directivity,
frequency response and source match errors.
Full 2-port/3-port/4-port calibration Compensation for directivity, reflection, transmission frequency response and
TRL/LRM calibration crosstalk in both forward and reverse directions. Provides the highest accuracy for
accuracy for coaxial and non-coaxial environments, such as on-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.
Velocity factor Enter the velocity factor to calculate the equivalent physical length.
Reference port extension Redefine the measurement plane from the plane where the calibration
was done.
Automatic port extension Compensates for both electrical length and insertion loss by measuring open
and/or short standard. Provides a simplified approach for fixture compensation.
Accessible calibration coefficients Calibration coefficients can be easily read and written 1 with programming
commands.
Mixer calibration 1
Scalar-mixer calibration Scalar-mixer calibration corrects the conversion loss for input port source match
and output port load match. Scalar-mixer calibration also corrects the input match
measurements for input port directivity, frequency response, and source match at
the input frequencies and corrects the output match measurements for output
port directivity, frequency response, and source match at output frequencies.
This calibration offers the conversion loss/gain measurements with correcting
the mismatches of both input and output test ports.
Vector-mixer calibration Vector-mixer calibration corrects for directivity, source match, load match,
and reflection frequency response at each test port by using a characterized
calibration mixer with de-embedding function. This calibration provides the
measurements of phase and absolute group delay. The characterization of the
calibration mixer is part of the calibration process.
