 The **Synthesis** tab checks how well your modal results describe the measured data. EDM uses the modes in a saved shape to rebuild (synthesize) each FRF, then draws the synthesized FRF on top of the measured FRF. If the modes were picked well, the two curves lie close together in the frequency band that was curve-fitted. The **Synthesis** tab checks how well your modal results describe the measured data.

-**Zoom Back**- Returns to the previous zoom level. 
- 
-**Un-zoom All**- Returns to the full view of the chart. 
- 
-**Remove Cursor**- Removes one mode cursor from the chart. 
- 
-**Remove All Cursor**- Removes all the mode cursors from the chart. 
- 
-**Horizontal Axis**- Shows the frequency axis on a **Linear** or **Log** scale. 
- 
-**Vertical Axis**- Changes how the FRFs are displayed: 
-  * **Magnitude, dB + Phase** 
-  * **Log Magnitude + Phase** 
-  * **Magnitude + Phase** 
-  * **Real + Imaginary** 
- 
-**Edit Legend**- Changes the names and colors of the curves in the legend. 
- 
-**Export Signal**- Saves the measured FRF and the synthesized FRF of the signal shown on the chart to a Universal File Format (''.unv'') file. Only the curve-fitted band is exported. Select a signal in the table before you use this option.
