FRF - Display Data

This screen shows the FRF measurement data. 
The upper trace shows the magnitude. Colour indicates the coherence of the measurement: frequencies with good coherence (≥85%) are shown in green and frequencies with poor coherence (<85%) in red.
The lower trace shows the phase.

During acquisition with Accept/Reject set to Manual the two traces show the Hammer and Response time traces.
