蓝牙音频测试 / Bluetooth Testing Seminar

/in /by

June 3rd 2021. 10am (China Time)

This seminar has now passed, but you can watch the video.

In this 1hr online seminar, S&V Samford presents Les Quindipan of Listen, Inc. and Kristopher Hett of Portland Tool & Die demonstrating 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.

在这1小时的在线研讨会中，声振环保仪器有限公司, Listen,Inc. 的Les Quindipan以及Portland Tool＆Die的Kristopher Hett，会向大家演示如何测试蓝牙设备。

届时Kris Hett会介绍Portland Tool＆Die蓝牙接口，该接口用于连接戴测试至测量系统。他将会讨论技术规范，并解释这些和其他类型的蓝牙接口之间的区别。

Les Quindipan将演示如何将它们完全集成到SoundCheck中以进行简单即插即用的操作，以及如何将它们用于测试程序中。他还会重点介绍SoundCheck的一些算法，这些算法可以克服蓝牙引起的时间延迟，从而使这些设备能够使用与有线等同类产品类似的方式进行测试。除此之外还会演示蓝牙扬声器和蓝牙耳机的完整测试。

该研讨会不收取任何费用，但需要注册。

Advanced Microphone Measurement Seminar / 麦克风测试进阶篇网络研讨会

/in /by

April 14, 2021. 9.30am (China time)

In this 120 minute online seminar, S&V Samford presents Listen’s Technical Support Manager, Steve Tatarunis, discussing some of the more advanced aspects of microphone testing including:

  • Substitution, Equalized Source and Transfer Function sequences in SoundCheck, including how to calibrate for these measurements. This is an expansion of material covered in the ‘basic microphone testing webinar’ and include more details about the sequences and calibration and the trade-offs of each method.
  • Advanced measurements including polar plot, phase, self-noise, signal to noise, distortion, active/passive noise rejection
  • Open loop microphone testing for voice activated devices such as smart speakers, automotive audio etc.
  • Advanced hardware and test configurations for measuring microphone arrays and MEMS devices

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