Coefficients for Calibration Standards
Use the Anritsu calibration kit USB Memory Device to load kit coefficients and characterization files.
Enter manual coefficients into user-defined locations.
Use complex load models.
Reference Impedance Modify the reference impedance from 50 Ω to any impedance greater than 0 Ω.
Interpolation Allows interpolation between calibration frequency points.
Adapter Removal Calibration Characterizes and “removes” an adapter that is used during calibration that will not be used for subsequent
device measurements; for accurate measurement of non-insertable devices.
Dispersion Compensation Selectable as Coaxial, other non-dispersive (e.g., for coplanar waveguide), Waveguide, or Microstrip.
Power
Power Meter Correction Different power meter calibrations are available to enhance power accuracy at the desired reference plane (to
usually approximately 0.1 dB for short periods of time).
Flat Power Calibrations A flat power calibration (when in frequency sweep mode) is available at a user-selectable power level, if it is
within the power adjustment range of the internal source. The flat power correction is applied to other power
levels.
Linear Power Calibrations A linear power calibration is performed over a range of power levels for use in power sweep mode and is
performed at a specified frequency or frequency range.
External Power Meter Both calibrations are performed using an external power meter (Anritsu ML2438A, ML248xB, ML249xA,
Agilent 437, or equivalent) over the Dedicated GPIB port.
Embedding/De-embedding The MS4640B is equipped with an Embedding/De-embedding system.
De-embedding De-embedding is generally used for removal of test fixture contributions, modeled networks and other networks
described by S-parameters (s2p files) from measurements.
Embedding Similarly, the Embedding function can be used to simulate matching circuits for optimizing amplifier designs or
simply adding effects of a known structure to a measurement.
Multiple Networks Multiple networks can be embedded/de-embedded and changing the port and network orientations is handled
easily.
Extraction Utility An extraction utility is part of this package that allows the easier computation of de-embedding files based on
some additional calibration steps and measurements.
Impedance Conversion Allows entry of different reference impedances (complex values) for different ports
Mixer Setup Mixer setup provides assistance to configure common mixer measurements including a simple, yet accurate,
calibration methodology.
Mixer Setup – Single Channel The prime objective of the guided Mixer Setup Single Channel is to help configure the frequency plan of the
measurement using easy-to-understand diagrams.
Mixer Setup – Multiple Channel The Mixer Setup Multiple Channels helps configure measurement channels to handle any of a suite of possible
mixer measurements and to list the required calibration steps.
Mixer Calibration Both of these tools are coupled with the mixer calibration menu system that enables both scalar and
vector-corrected measurements.
