Impedance Sweep

Use this command to perform a simple impedance sweep without the extraction of any parameters. Driver parameters will be cleared to prevent any confusion.

Impedance Calibration...

When first installed, WT3 is calibrated to within about 2% for the impedance range under 100 Ohms. This is adequate for measuring driver parameters. For even finer calibration you can use this command to custom calibrate the system for your particular WT3 hardware unit. When you select this command the impedance calibration dialog (shown below) will open.

Enter the actual value of the calibration resistor you are using (if different from the recommended 1k Ohms). Then, connect the calibration resistor to the WT3 test leads and click OK. The software will measure the calibration resistor and adjust its internal calibration accordingly. After calibration, you might want to make another measurement of the calibration resistor to confirm the new calibration. By design, WT3 is most accurate in the lower impedance range with accuracy decreasing at higher impedances (above 1k Ohms). Calibration in the lower impedance range will typically be improved to within 1% following calibration at 1k Ohms with the 1% resistor included with the unit. You can actually calibrate the unit with any convenient resistor in the range from about 500 to 2k Ohms. It is important that the actual value of the resistor be known to within 1%. High quality digital multi-meters will often be able to measure any resistor to within 1%.

When you exit the application the new calibration will be remembered for your next session. Impedance calibration only needs to be performed one time after the software is installed on a PC.

WT3 specifications

The Dayton WT3 is a sophisticated and highly regarded tool in the field of audio measurement and analysis, particularly known for its precision in loudspeaker testing. This comprehensive device integrates several advanced features and technologies, making it an essential choice for audio professionals, engineers, and hobbyists alike.

One of the standout characteristics of the Dayton WT3 is its dual-channel capability, allowing users to conduct simultaneous measurements of two different loudspeakers. This feature is particularly useful in stereo systems where matching drivers is essential. The WT3 utilizes a high-resolution analog-to-digital converter (ADC) that ensures accurate and detailed frequency response measurements, providing users with the data they need to refine and optimize their audio setups.

The WT3 is equipped with a user-friendly interface that simplifies the measurement process. Its software is intuitive and runs on Windows, which means that users can easily navigate through various options to configure tests and analyze results. The inclusion of a built-in microphone makes it possible to perform room acoustics measurements, further enhancing its versatility.

Another key technology integrated into the Dayton WT3 is its frequency sweep capability. By generating continuous sine wave sweeps across a wide frequency range, the WT3 can analyze the response of loudspeakers in real-time. This allows for identifying resonances, distortion, and other critical parameters that affect sound quality.

The WT3 also features a range of measurement modes, including impedance measurements, which can be invaluable for understanding how a loudspeaker behaves across different frequencies. This data is displayed in easy-to-read graphs and charts, facilitating a straightforward interpretation of results.

Moreover, the Dayton WT3 utilizes advanced signal processing algorithms that help in reducing noise and other unwanted artifacts that can skew measurements. The device's accurate phase response measurement capability further distinguishes it from competitors, providing essential data for crossover design and speaker alignment.

In summary, the Dayton WT3 combines advanced measurement technology with an intuitive user experience, making it an essential tool for those seeking precise loudspeaker performance insights. Its features and capabilities position it as a valuable asset for both professional audio engineers and enthusiasts dedicated to achieving the best possible sound quality. Whether for designing new speakers or optimizing existing setups, the WT3 delivers reliable performance and accuracy.
