Digital Audio Amplifier Testing

[smoken]

Hello my beloved member,

First of all I just to thank everyone for helping other members like me who are new in testing system.

I want to develop a tester for digital audio amplifier, i dont know where to start and what to do. Can someone tell me what hardware should I use, the software to use for it and some codes to start about the development of this tester.

Basically I will test a PCB of a digital audio amplifier that have a pogo pins that will have to contact the test points on the PCB and a connection going into the PC.

Any help will be greatly appreciated.

anyone who can help me on this? thanks a lot for the help

Without any details on what you want to test the amplifier for, we cannot provide any useful suggestions. Suggest you first acquire or create the acceptance test plan and it's relevant parameters, that will assist in guiding what hardware/software you should procure.

Hello smoken,

I agree that a few details (or list of tests) would help us better help you. However, I think I can answer the software question right off the bat: LabVIEW of course! If you've never used LabVIEW before, there are plenty of resources to help you get started:

I suspect for the hardware you'll want to use some sort of DMM or DAQ board, though it really depends on the accuracy you want (in addition to the types of measurements). You might want to check out our customer solutions page to see if that sparks any ideas:

I searched for "digial amplifier" and found quite a few articles. You can also contact your local technical representative to discuss options. (888-280-7645) In any case, let us know some specifics and I'm sure you'll find answers!

Hope this helps,
