Dayton Audio DATS Dayton Audio Test System
The highly successful Dayton Audio WT3 speaker tester has now outgrown its name! DATS, the Dayton Audio Test System, is the proud successor to the WT3, includes everything WT3 users have come to love about that systembut adds much more. Don't worry, the new system still measures loudspeaker parameters or R, L, and C values in just seconds and still includes the WT3's unique Rub and Buzz test. But now with the introduction of DATS, the system has grown beyond impedance testing and T/S measurements to include a second test mode featuring a general purpose signal generator and oscilloscope working in tandem.
The scope and generator combination provides a powerful general purpose audio test set. When used with the DATS hardware, the oscilloscope monitors the DATS generator output and is calibrated. When standard audio interfaces are available, the oscilloscope input can be switched to another device to allow the monitoring of arbitrary input signals in addition to the DATS generator output.
DATS provides the following improvements over WT3:
* New signal generator with selectable waveform, frequency, and amplitude
* Sine, square, triangle, saw tooth, impulse, pink noise, and log sweeps
* New oscilloscope with dual traces and adjustable time and amplitude scales
* Oscilloscope and generator compatible with other audio interfaces
* Improved audio device selection dialogue
* Improved alligator clip leads provide a more consistent test lead impedance
* New method for calculating Vas from specified Mmd
* Faster hardware startup time (reduced from 90 seconds to 30 seconds)
DATS measures over 30,000 data points in just a few seconds using a new swept sine technique. The result is a very high-resolution impedance measurement that allows the extraction of an extremely accurate driver parameter set, suitable for the most critical loudspeaker design work.
Free air parameters are measured in just a few seconds. Vas can be measured by traditional test box, added mass, SPL, or calculated from the driver's specified Mmd. No other impedance tester is as fast, versatile, or as easy to use as DATS.
DATS hardware consists of a compact USB interface unit with attached USB cable and alligator clip leads. It's manufactured on state-of-the-art equipment using precision surface mount components. Windows compatible software provides an easy-to-use interface that allows you to be up and running very quickly. You can save as many as 20 impedance measurements per project and then overlay and compare any or all of the measurements to create a custom report complete with all your notes. Perfect for quick incoming QC inspections.
Minimum System Requirements: IBM PC or compatible system with 64MB RAM; 500 MHz Pentium III processor; MS Windows 98, Me, NT, 2000, XP, 7, or Vista; One available USB 2.0/1.1 port.
