Features

Linear Vertical Scale in S-parameters

S-parameters can now be viewed on a linear vertical scale. The usefulness of this feature is primarily evident when viewing transfer parameters in PDN analyses. For example, if you drive a PDN with a current source and probe the PDN voltage rail, the transfer characteristic is one of V/A = ohms. Therefore, when viewing the transfer characteristic on a linear vertical scale, the readout is in PDN impedance in ohms.

Headless Simulations and S-parameter Calculation Callbacks

Now, when performing a simulation or s-parameter calculation in a "headless" mode (when opening a project and running the project from a script), a callback function can be provided. This is useful to track the progress of the calculation from a script.

Relay contacts increased to 17

so that a 16 contact relay with a common can be used.

Skin-effect Resistor

A resistor device has been added where all of the resistance is due to skin effect (i.e. has a resistance specified in ohms/sqrt(Hz)).

SOLR calibration with no thru provided

Previously, a thru standard estimate was required for SOLR calibrations. Now, it is possible to let the algorithm determine the thru with no estimate provided. This should only be used with highly sampled s-parameters.

Bugs

Resampling in VNA Calibrations

When performing VNA calibrations, the measurements were not being resampled, which is a bug. This meant that the measurements provided must be on the exact same frequency scale as specified in the project in order to work. This has now been corrected and the measurements are resampled onto the project frequency scale.

See Installation for installation instructions.
