Production Testing Seminar China / 产線测试网络研讨会

loudspeaker production lineMay 18th 2022. 10am (China Time) / 2022年5月18日上午10点(中国时间)

In this short seminar, Les Quindipan explores the use of SoundCheck for end-of-line production testing. He discusses typical test configurations and the type of measurements that can be made, how to set pass/fail limits and how to optimize tests for high throughput.

He will also explain how SoundCheck is easily scaled for high volume production testing, with such features as external control via another program and auto-saving data to databases, and how SoundCheck’s capabilities are easily expanded through the use of custom steps to control all types of devices and test fixtures.

This seminar will be of interest to anyone considering a production line implementation of SoundCheck, or curious as to how to transition R&D measurements to fast and effective end-of-line test.

There is no charge for this seminar, but registration is required.

Virtual Instruments Seminar

April 12th, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)

Virtual instruments, included in SoundCheck,  are a cost-effective and portable software-based alternative to hardware instrumentation, ideal for making quick measurements or viewing device behavior in real time. In this educational seminar, Les Quindipan walks through a demonstration of the virtual instruments in SoundCheck, showing off some of their lesser-known capabilities. These include the signal generator, multimeter, oscilloscope/spectrum analyzer, real time analyzer, frequency counter and distortion analyzer. The strip chart recorder, which expands the capability of these instruments to record measurements over a period of time, will also be discussed.

Note: We will be repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford. A sign-up link will be available shortly.

Bluetooth Device Measurement Seminar

This event has already taken place, but you can view the recording here.

 

May 27th, 2021. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)

In this 1hr online seminar, Les Quindipan of Listen, Inc. and Kristopher Hett of Portland Tool & Die demonstrate how to test Bluetooth devices.

Kris Hett will introduce the Portland Tool & Die Bluetooth interfaces that are used to connect the device under test to the measurement system. He will discuss the technical specifications, and explain the differences between these and other types of Bluetooth interfaces. Les Quindipan will then demonstrate how these have been fully integrated into SoundCheck for simple plug and play operation, and how they can be used in test sequences. He will also highlight some of the algorithms included in SoundCheck that overcome Bluetooth-induced time delays, thus enabling these devices to be tested in a similar way to their wired counterparts. A complete test on a Bluetooth speaker and a Bluetooth Headset will be demonstrated.

There is no charge for this seminar, but registration is required.

Note: We are repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford,  on June 3rd at 10.00am China time. Please register for this seminar instead if this timing suits you better or you prefer the slides translated into Chinese.

无需消声室的20-20kHz自由场测量 / 20-20kHz Free Field Measurements Without an Anechoic Chamber

2021年3月17日,上午10点(中国时区)

在本在线研讨会上, Steve Temme将解释如何在无需消声室的情況下,使用模拟自由场测量,在整个可听频率范围内提供准确的自由场测量。这样能让通常要在消声室中进行的测量可以在常规实验室甚至家中进行,这是对于当前在家工作的许多人来说是一项非常宝贵功能。

此测量方法自2001年以来已在SoundCheck中使用,它可以测量低频下的近场响应和高频下的时间窗口远场测量,并将它们拼接在一起以提供整个频率范围内的响应。

 

在这次研讨会中,我们将解释该方法背后的声学和数学原理,并通过预先编写的(免费的)SoundCheck测试序列演示测试程序,并说明结果与消声室内的测量结果之间的关系。

该研讨会不收取任何费用,但需要预先注册。
