9.3 RTA - OCTAVE BANDS ANALYZER
Fig. 9.2 The RTA control panel
Pressing the RTA button you select the octave bands analyzer. Fig. 9.2 shows the
RTA control panel (while analyzing the 1/3 octave response of a HT center channel
speaker). The RTA (RT stands for real-time) analyzer is a dedicated instrument that
is normally used to measure the averaged frequency content of an acoustical signal
and for evaluating how a complete reproduction system (from PA to HT) behaves in
a real environment.
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.
