Response Panel |
The Response panel provides vertical and horizontal cross-hairs with a dynamic frequency and dB read-out. Place the mouse courser over the graph to activate the cross-hairs. When the Phase control is activated, the horizontal cross-hair line to the left of center represents the normal curve, the right side represents the phase curve. The readout is only for the normal curve. |
X-Axis = 20 Hz to 20 kHz Y-Axis Left = -24 dB to 24 dB Y Axis Right = -180° to -180° |
