Medical and Defense: Multimedia Subsystem Test

"By transitioning from our in-house solution to the NI PXI and NI AudioMASTER solution, we can now execute 10 times as many tests per device without an increase in test time, and have freed up our engineering team to focus on other core business tasks. Additionally, we no longer worry if our platform can handle future test requirements such as radio frequency (RF) telemetry or other unforeseen requirements."
