Setting Parameters
Parameters are entered in the Block Parameters window/tab or via the AI chat.
Manual entry in the workbench/pop up view
- Click the field you want to edit (click the value, or click an empty cell in the column)
- Type the value — use the same units shown in the field label (dB, dBm, MHz, etc.)
- Press Tab (move to next field) or Enter (confirm and stay) to save
- Press Esc to cancel without saving
The value is saved immediately and the analysis re-runs.
Units conventions
| Parameter type | Units | Sign convention |
|---|---|---|
| Gain (active) | dB | Positive |
| Gain (passive/loss) | dB | Negative (e.g., −1.5 for 1.5 dB insertion loss) |
| Intercept points (IIP3, OIP3, P1dB) | dBm | Positive or Negative |
| Frequencies | MHz | Always Positive |
| Powers | dBm | Positive or Negative |
Clearing a value vs. setting to zero
| What you do | Effect |
|---|---|
Type 0 and confirm | Sets parameter to 0 — valid value, treated as a real measurement |
| Delete all text and confirm | Clears the parameter — downstream metrics go to UNKNOWN |
A cleared parameter is explicitly "not set." A zero is a real value (e.g., 0 dB gain = unity gain buffer). Never use zero to represent an unknown — clear the field instead.
Datasheet parser apply follows the same distinction. Parser-applied values are marked as datasheet-sourced, and old datasheet-sourced values can be removed during a later parser apply so stale values do not remain. User-entered values are preserved unless you choose to replace them in the conflict review step.
Default vs. advanced view
The workbench shows a default set of parameters by default. Click Select visible params to reveal extra parameters if available.
Bulk entry via chat
You can set multiple parameters at once:
Set the LNA gain to 18 dB, NF to 1.5 dB, and IIP3 to −5 dBm
This is equivalent to editing each field manually. Values are recorded with LLM source.
Parameter visibility by component
Not all parameters apply to all roles. Only the parameters that are relevant to each block's role are shown
