Simple BER meter is easy to build

Posted on Jun 24, 2012

A bit-error-rate (BER) tester is a basic tool for digital-communications measurements. Although many commercial BER testers are available, you can easily design and build an inexpensive version. The scheme in Figure 1 has performance similar to that of a commercial tester but requires you to perform a manual calculation based on displayed data. The tester displays received bits and received erroneous bits, and you must calculate the BER data using a handheld calculator, for example.
