S parameter files are great, but they only affect Gain! When you need the value of other parameters to automatically change with frequency and temperature, you need our Multiple Values feature.

Adding Multiple Values

Find the component and parameter that you want to have multiple values for. Click the parameter name to open up the edit modal:

Click the enable/disable toggle next to the multiple values section to turn the feature on.

For each data point you have simply provide the frequency, temperature, and parameter value. Then click “ADD”.

You’ll notice the value at the top of the modal will change as you provide values.

When you’re done, click “SAVE”. From now on the value of your parameter will be calculated for you.

Using Multiple Values

When you change the frequency or temperature at a Source component all downstream components will re-calculate their parameter values using the multiple values you provide.

If your choice of temperature and frequency at the source exactly match one of your data points, then that value will be used.

If your choice of temperature is greater than the highest temperature in your data points, then the value will be snapped to that highest data point. Similarly for frequency.

If your choice of temperature is smaller than the lowest temperature in your data points, then the value will be snapped to that lowest data point. Similarly for frequency.

In all other cases the value will be determined by linearly interpolating between the closest data points.
