The P33 Real-Time Analyzer comes with the software and download cable included in the price.
The meter has both USB and RS232 ports and so should connect to your computer without difficulty.
The Acoustic Toolbox software offers the following features:
The sound level meter can be controlled remotely via RS232, USB or optionally over a modem/GSM link. The sound levels in real-time can be displayed numerically or graphically, for both broadband and filtered modes.
Although measurements can be displayed in tables, it is usually much more useful to have them in graphical format. These graphs can easily be copied into Word or similar word processing or publishing software.
With so many different data sets available from the meter, often the most useful option is to export the data to Excel (or similar spreadsheet program) so that you can easily create custom reports, graphs and calculations.
All measurements can be exported in this way, from simple broadband results to 1/3 octave band spectra repeated every 125 ms.
The real-time analyzer has built-in menus, so you can configure it without having to connect to a computer. However, it is often easier to configure it from the computer screen. There are many different settings, but here are the most commonly used ones:
All these settings can be changed in the field, but it is useful to be able to set the meter's default settings to those you use most.
This software is included free-of-charge with the meter and may be freely installed on any computer without restriction. Upgrades are made available on the Internet as they become available.
