The pcRTA can display measured data in a variety of different formats including: bar graph, text chart, and line graph. Each display graph has user definable characteristics such as color, fonts, and fully adjustable scales- both absolute and relative. The user can easily custom design any graph for screen display or printing. Moreover, any and all graphs can be printed through any standard Windows printer driver to virtually any printer in full color or black & white.

The pcRTA has four separate measurement modes. Each mode has a different set of controls and graphs. The descriptions below provide an introduction to the detailed pages which follow.

• Amplitude Mode
Amplitude Mode simply refers to the usual dBm or dBspl data measured by all RTAs. This is the general purpose mode of the analyzer for taking normal RTA measurements.

• Noise Analysis Mode
This modes records and/or averages signals and noise over a finite period of time, and then generates statistical analysis and graphs. Time periods ranging from 1 minute to 24 hours are supported. This mode produces environmental noise measurements of LEQ, LNP, L10, L90, LOSHA. The pcRTA includes a complete set of all standard ANSI weighting filters A,B,C,D,E.

• Reverb Time Mode
Reverb Time is a measure of how sound decays in a closed environment. The Reverb Time mode provides the usual RT60 measurement, as well as RT40 and RT20 which handle more difficult and noisy room environments. 

• Impedance Mode
The Impedance Mode is provided for general speaker or passive crossover measurements. It supports both 2-wire and 4-wire methods, and is a handy feature that allows both passive networks and loudspeaker transducers to be easily and quickly measured.
