Virtual Instruments Seminar

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, are also discussed.

Virtual Instrument testing demonstrations include:

  • What are Virtual Instruments, and how to use them in SoundCheck
  • How instruments use existing SoundCheck signal paths and calibrations
  • Tour of individual instruments
  • Using multiple instruments and saving Virtual Instrument Configuration Files (or .vic files)
  • Explore using Virtual Instruments in a SoundCheck sequence
  • Practical applications of SoundCheck Virtual Instruments

Presenters: Les Quindipan
Duration: 30 Mins

Virtual Instrument measurement resources

Check out our main page on SoundCheck Features and Functionality for more detail on all of SoundCheck’s audio test and measurement capabilities.

The Virtual Instrument example sequence included in the SoundCheck installation is a great starting point for working with virtual instruments. The sequence automatically performs measurements with various virtual instrument configurations with operator message details about each configuration. This sequence can be used as a template sequence to build a custom test sequence.

The Multi-RTA virtual instrument in SoundCheck features true recursive digital filtering, and conforms to the ANSI S1.11-2004 standard.

Production Testing Seminar

In this short seminar, Les Quindipan explores the use of SoundCheck for end-of-line electroacoustic 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 also explains how SoundCheck is easily scaled for high volume electroacoustic 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 interest 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.

Production Testing demonstrations with SoundCheck include:

  • How to scale for high volume electroacoustic production testing, saving time and money
  • Typical audio measurements used in production testing
  • Production test setups
  • Optimizing test times and accuracy
  • Setting pass and fail limits in a test sequence
  • Auto-saving data
  • Custom Step Applications
  • Controlling SoundCheck externally from another program

Presenters: Les Quindipan
Duration: 18 Mins

Bluetooth Testing Seminar

Les Quindipan of Listen, Inc. and Kristopher Hett of Portland Tool & Die demonstrate Bluetooth testing with a variety devices, test parameters, and testing considerations. Kris Hett introduces the Portland Tool & Die Bluetooth interfaces that are used to connect the device under test to the measurement system. He discusses the technical specifications, and explains the differences between these and other types of Bluetooth interfaces. Les Quindipan then demonstrates how these have been fully integrated into SoundCheck for simple plug and play operation, and how they can be used in test sequences. He also highlights 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 is demonstrated.

Seminar demonstrations include:

  • Overview of Portland Tool & Die Bluetooth interfaces features and functionality
  • Portland Tool & Die software control integration with SoundCheck
  • SoundCheck configuration and calibration for testing Bluetooth devices
  • Software control of Portland Tool & Die devices within a SoundCheck sequence
  • Demonstrations of sequence measuring Bluetooth headsets and speakers

Presenters: Les Quindipan, Kristopher Hett
Duration: 30 Mins
