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.
