The flatness search function allows to determine and view the following trace parameters: gain, slope, and flatness. Two markers to specify the flatness search range should be set (See figure below).

Flatness Parameters Determination
| Parameter Description | Symbol | Definition | 
|---|---|---|
| Gain | gain | Marker 1 value. | 
| Slope | slope | Difference between marker 2 and marker 1 values. | 
| Flatness | flat | Sum of "positive" and "negative" peaks of the trace, which are measured from the line connecting marker 1 and marker 2 (See above figure). |
