Virtual Instruments in SoundCheck are a quick and easy way to take a measurement without developing a full test sequence, for example to check a level in the multimeter or view an FFT spectrum in the Spectrum Analyzer. They also offer amazing versatility when used in a test sequence to acquire data for further analysis, post-processing, etc. Watch this short video to learn more.

Video Script: Quick Measurements with Virtual Instruments
Virtual Instruments in SoundCheck are a quick and easy way to take a measurement without developing a full test sequence. This might be useful if, for example, you want to check a level in the multimeter or view an FFT spectrum in the Spectrum Analyzer. And, all of the measurements in SoundCheck meters can be saved to SoundCheck’s memory list.
However, did you also know that SoundCheck instruments can be used in a test sequence? A Virtual Instrument acquisition step can be created to acquire from a device you want to measure. This adds yet another way in SoundCheck to acquire data for further analysis, post-processing, etc.
You can even use multiple Instruments manually or in a virtual instrument acquisition step. Here’s an example of a virtual instrument acquisition step that acquires input from the reference mic and calculates the level and RTA spectrum [show screen capture of sequence]. Once acquired, the data can be processed like any other data in SoundCheck. For example, the level or RTA spectrum can be passed through a pass/fail limits step. This might be useful for measuring input-only noise, for example: fan noise from your product.
In this example, you can use a signal generator and mult-RTA in a Virtual Instrument acquisition to measure the individual channel of a 6-mic array along with the power sum of the 6 channels [screen capture of sequence]. The acquired data is captured to the curves tab of the memory list.
As you see, integrating virtual instruments as a step in SoundCheck is very easy, and another example of SoundCheck’s testing flexibility.
