DATS V3 Computer Based Audio Component Test System

When designing the DATS V3 measurement device, Dayton Audio took everything customers love about the DATS V2 and improved upon the accuracy, capability, reliability, convenience, and flexibility.

Any engineer knows that valid and accurate data is crucial to great results. DATS (Dayton Audio Test System) V3 is the essential tool in any speaker designers or audio engineers toolbox, providing accurate, precise measurement data for any audio transducer or loudspeaker system. Save yourself time, money, and trial-and-error frustration by using DATS V3 to measure loudspeaker drivers, crossover networks, and complete audio systems!

DATS V3 is a unique, multipurpose test system that works with your PC and full-featured test software to measure the impedance response of a speaker driver and derive a complete set of Thiele/Small parameters that describe its operation. Its as easy as connecting a driver and starting the test! The DATS V3 measurement module provides the electrical stimulus to the driver, measures the drivers impedance on the fly, and then creates a high-resolution graph (30,000 data points!) with no additional hardware required.

Whats better about Version 3?

From the outside, the DATS V3 has a completely updated look and feel. The extruded aluminum housing makes DATS V3 durable enough to throw into a toolbox without worrying about damage. In addition, optional mounting brackets give you the option to mount the DATS V3 under a desk or test bench to save space. No more searching for a calibration resistor, it is now integrated into the case, just clip the test leads onto the pins on the front of the housing and run the calibration. Also, the test leads have been upgraded to removable insulated banana plug test leads, giving you the ability to use your favorite test leads and easily replace damaged test leads (test leads are included). Finally, we have added a USB-B jack rather than an integrated USB cable (USB A to B cable included). This allows the cable to be quickly swapped if there is any damage, or if a different length is preferred.

The improvements continue on to the inside of the DATS V3. The internals have been completely redesigned and improved to deliver better accuracy and more power. With increased output power, the DATS V3 allows you to take measurements at a higher level to minimize the chance that a high noise floor or vibration could affect measurement results. Dayton Audio has also upgraded many of the internal components with tighter tolerances to minimize the margin of error that is caused by a components value variance. Even the calibration resistor has been upgraded to 0.1% tolerance.

DATS V3 software is the true power of DATS. The included software not only measures impedance and parameters of speaker drivers with incredible accuracy, but the addition of the DATS Linearity Test gives you the ability to observe changes in parameters with differing drive levels. The Linearity Test automatically performs multiple sweeps of the driver at increasing (or decreasing) levels while saving each test result to memory making it easy to recall and compare the results. As always, the DATS V3 still has the capability to measure the true value of inductors, capacitors, and resistors, and it also works as a signal generator and scope to let you monitor small electrical signals (line-level only). Even more updates are planned to further set DATS V3 apart from the competition.

DATS V3 provides the following unique advantages:

• Rugged aluminum housing with detachable test leads and built-in precision calibration resistor
