Improvements in DC processing, more devices, and added network analysis capability

New Devices

DC Voltage and Current Sources

These are much needed devices that enhance the capability of setting DC points. Previously, this was a cumbersome exercise involving creating a step source that starts at some distant time in the past, requiring the simulation to start only after these DC waveforms stabilized. Now, DC voltage and current sources are not waveforms, but just numbers representing their values. During processing, the DC (number) waveforms are processed by taking the DC frequency response of the filter they are passing through, as opposed to convolution with the impulse response. In addition to these simplifications, DC sources do not require time length, sample rate, etc. They are just always there.

Laplace Device

This is a device that allows the user to directly enter an equation for the S21 in s, w, or f. The remainder of the device performs like an amplifier with infinite input impedance, zero output impedance, and perfect reverse isolation. This device is useful for generating flexible DSP building blocks when the desired function is not available.

Xtalk Calibration Measurement

Previously, for VNA calibrations, two types of calibration measurements were supported: Thru and Reflect. Now, the less often used cross-talk measurement has been added. This had been usable through scripted applications, but it has now been added to the GUI.

Bug Fixes

Honoring 12458 sequence preference in s-parameter property changes

In a previous release, this was added as a preference for the calculation properties, but was missed for s-parameter properties. This is now fixed.

All documentation is up to date with this release. See Installation for installation instructions.
