System Analysis/Models

- Nonlinear parameters such as P1dB, Psat, and intercept points for non-linear models (amplifiers, nonlinear block, and mixers) now support input impedance corrections. What this means is that you can now enter the measured impedance of their device along with the mentioned nonlinear parameters from the datasheet and internally in the simulator, the non-linear parameters will be corrected for the mismatch to provide the expected results for the given non-linear parameters. This addresses an issue when the PortParamType parameter was changed on non-linear devices to use an impedance other than the reference impedance, which resulted in the actual compression, saturation, and intercepts points to be incorrect.
- Added four new intercept point measurements (OIP3_OneTone, OIP2_OneTone, IIP3_OneTone, and IIP2_OneTone) which simulate the 2nd and 3rd order intercept points based on a single tone. Intermod measurements for Quick Sweeps are improved to use the single tone intercept points that support both 2nd and 3rd orders. Using these measurements also increased measurement accuracy and speed. It is also simpler to use because a 2nd tone does not need to be configured. See examples RF Amp One Tone Intercept Points.wsv and RF Amp Intercept Quick Sweep.wsv.

Note: The OIP3_OneTone and IIP3_OneTone measurements do not work with X parameters because harmonic balance simulations, needed for X parameters, do not support signals underneath signals and would be considered a colliding tone.

- The RF_AMP model can now generate higher-order (>3) harmonics and intermods up to 11th order (see examples RF Amp 11th Order Intermods.wsv and RF Amp Intercept Quick Sweep.wsv). The same algorithm used to generate data flow coefficients for 5th, 7th, 9th, and 11th order from PSat, IP3, and P1dB is used in the Spectrasys RF amplifier. Even order intercept points are estimated using measured data of several typical RF amplifiers.

RF_Link Simulation

- Improved simulation result agreement between Spectrasys and RF_Link.
. The Spectrasys RF_AMP model is now using the same non-linear polynomial coefficients (for 3rd. 5th, 7th, 9th, and 11th order terms) used by the Data Flow Amplifier model given values for PSat, IP3 (TOIout), and P1dB (dBc1out).
. One tone IP3 measurements are added to provide the capability of extracting those parameters needed in the Data Flow model by using only a single tone.
. There are still some differences in the intermod amplitude levels when the input power is within 10 dB or so of the compression point due to the differences in the way coherency is handled between Spectrasys and Data Flow. See Cosimulation Signal Coherency for additional information.
- The RF_Link model is now supported in SVE (SystemVue Engine). Since Spectrasys is not part of SVE, SVE cannot characterize the behavior of the RF system and must use characterization data generated by SystemVue. There are new settings in RF_Link to control when the behavioral (characterization) data is generated. This data should be recalculated whenever there's a change in the RF system or the sampling rate and/or characterization frequency of the RF_Link input signal changes. By default, the data is always recalculated and will always be up-to-date.
- Improvements were made to modeling mismatches.
- RF_Link now supports the MIXER_TBL model and can generate IM products from higher LO and input harmonics that end up falling in the simulation bandwidth.

Linear Analysis

- The Linear Simulator is now included with the RF Toolkit (Spectrasys and related tools) so that S-parameters can be calculated.

Cauton: RF design features like stability circles, gain circles, noise circles are not supported. Also, the transmission line or microstrip related features are not available.

MATLAB SVE Link

- MATLAB SystemVue Toolbox and associated models (MATLAB_Link, MATLAB_LinkCx, and MATLAB_LinkEnv) allow MATLAB users seamlessly stream data to/from a SystemVue design while in the MATLAB environment (see examples under Examples\Tutorials\Algorithm_Design\MATLAB_Toolbox).
- Link models can be used to only stream data to SystemVue, only stream data from SystemVue, or both.
- The SystemVue design is simulated using SystemVue Engine (SVE).
- MATLAB SystemVue Toolbox provides a function to read variables directly from a SystemVue Engine simulation dataset (adx format).
- The MATLAB SystemVue Toolbox is only supported on Windows.

Platform

- Improved the sweep simulation output log to capture information from all simulations run during the sweep. Both distributed and non-distributed simulation logs have been improved.
- The Parameter Synchronization Tool enables easy comparison and synchronization of matching model or design parameters. Both part and design parameters can be synchronized. Either (1) select one or more parts on a schematic, right-click, and select "Sync Part Parameters…" or (2) select one or more designs in the workspace tree, right-click, and select "Sync Design Parameters…".
- The Smith Chart graphs are now available to facilitate plotting S-Parameters. This is available for all versions of SystemVue (the RF Toolkit is not required).

Data Flow Analysis/Models

- The FastCircuitEnvelope and FastCircuitEnvelope_M models now support parameterized FCE files. The FCE file parameters can be set using variables so that they can be swept or tuned.
- The FastCircuitEnvelope and FastCircuitEnvelope_M models now support setting the Filename parameter using a variable and sweeping it.
- The ReadFileCx model can now read pairs of real numbers from a ascii file and interpret them as complex numbers.
- Added reset port to the Modulator and Modulator_M models to allow resetting internal phase accumulator when InputType parameter is set to Amp/Freq.

Link to AGI STK

- Link to AGI STK (STK_Interface) allows for retrieving data from an STK scenario and bringing it into SystemVue for use in setting up time-varying channel models. This feature used to be provided as a separate add-on. It is now part of the SystemVue installation with much-improved usability (custom GUI) and other features.

Phased Array Analysis

- Phased Array analysis can now export the directivity pattern to a file that can be read by AGI STK.

Modelbuilder

- A new example under the Examples\Model Building\C Modeling\Link Third-Party Library folder illustrates how to build a custom model linking to a 3rd party library.

Instrument Link

- A new example under Examples\Instruments\M9410\SignalDownloaderM9410.wsv the illustrates how to download an I/Q waveform into Keysight M9410A VXT PXI Vector Transceiver.

RF Libraries

- The Analog Devices RF parts library has been updated
- The Custom MMIC RF parts library has been updated
- The X-Microwave library has been updated. The old X-Microwave library is now obsolete but has has been left in the product to allow workspaces created with prior versions to be loaded and simulated. Several changes have been made to the X-Microwave library. They are listed as follows:
. All parts are now in a single library. There are no longer individual libraries for each X-Microwave component vendor.
. The default symbol is now the system behavioral symbol.
. Each part now has a SymbolMode parameter which defaults to the system behavioral symbol. The user can change this to Hybrid where a physical representation that corresponds to the purchasable X-Microwave block. This can be extremely valuable as the final schematic will very closely represent the X-Microwave hardware. NOTE: The schematic connectivity may break and the respective symbol pins may be in different locations that may also require schematic rewiring. The most effective way to use these parts is to change the symbol, if so desired, before wiring the part.

Data Flow Analysis/Models

- Fixed issue with interpolation of S-parameter data resulting in incorrect results.
- Fixed issue where for a wideband input signal placing a filter before or after a linear amplifier resulted in 3 dB difference in output signal level.
- Fixed issue with NonLin model using RevIM parameter incorrectly.
- Fixed some phase noise coherency issues associated with split paths, mixers, then combined back together when the phase noise was only on the input signals.
RF_Link Simulation
- Fixed issue where in some RF_Link simulations of RF systems with more than one mixers in cascade the simulation would error out with a message complaining about the mixer having a real baseband signal at its input.
Platform
- Fixed issue with workspace variables set using VB scripts not retaining their values after workspace is saved and reloaded.
