5.4.15.3 BERT
The Bit Error Rate Tester (BERT) option, shown in Figure 106, allows the user to measure system performance. It
does this by comparing received data to a specified data pattern and counting the ratio of errored bits to total
received bits. This may be useful for various forms of system testing, including transmitter or receiver RF integrity
verification. The Browser provides the ability to set BERT parameters and access BERT status information.
