DATS V2 Revision History
7Aug14 : DATS version
2.0.0 is initially released
Changes from DATS 1.0:
setup: The new DATS V2 hardware greatly
simplifies setup such that most users can just plug it
in and start testing without needing to fiddle with
Windows audio settings.
The new capacitor measurement module goes beyond just
measuring the capacitor’s value and now includes
measurement of the capacitor's equivalent series
resistance (ESR), dissipation factor (DF), quality
factor (Q) and loss angle (δ) at three different
frequencies: 120, 1k and 10k Hz.
Loudspeaker parameter measurement has been expanded to
include the Wright
parameters which are especially
useful for precision simulation. The Wright parameters
allow for the
accurate reproduction of a driver's
high frequency inductive impedance from the four new
XR KI and XI.
Log Impedance Scale:
A new user setting allows easy switching between linear
impedance scales. Often it is
convenient to view impedance on a log scale because the
impedance of a
pure capacitor or inductor becomes a
straight line and any non-linearity is seen at a glance.
The new log
impedance scale has adjustments for both
upper and lower impedance plot limits.
Significant Digits Displayed:
A new preference allows the user to set the number of
significant digits that will be displayed.
Greatly Expanded User's
Guide: New Tech Notes have been added covering
Speaker Parameter Measurement, Inductance Modeling and
Capacitor Measurement. Several relevant excerpts from
Introduction to Loudspeaker Design 2nd Edition have been
