9.10 “LIVE” TRANSFER FUNCTION ANALYZER
Fig. 9.3 The Live transfer function control panel
Pressing the Live transfer function button the instrument behaves as a dual channel FFT
analyzer referencing one channel to the other and calculating the transfer function
between the two. Fig. 9.3 shows the Live transfer function control panel (while
measuring the frequency and phase response of a loudspeaker). The Live transfer
function analyzer is a the fastest way to measure frequency response and has been
optimized for interactive and fast refreshing live situations when the only available signal
is reproduced music.
For a detailed description of the graphical display (common also to other measurement
control panels) and its capabilities please refer to Chapter 7. For a description of the
available shortcuts please refer to section 5.5.2.
9.10.1 DEDICATED ‘LIVE’ TOOLBAR FUNCTIONS
Fig. 9.4 The Live transfer function toolbar
Enables the Time Data display. The lower graph displayed is the impulse response.
Enables phase response to be displayed in the lower graph.
Enables coherence response. The coherence is displayed in the same graph of the
transfer function magnitude and reads on the right displays scale.
Automatically evaluates the interchannel delay and sets it. The value of the delay is
shown in the delay display.
