A summary is shown in Table 1 . IF Use eye diagram Demodulator output Gate a raw PN sequence output and send for BER measurement. Baseband output Recover clock, decoded payload data, Send for BER measurement. A complete unit requires use of Bluetooth test mde. Baseband and link processing must be included.
Some designs allow it to be done with custom settings.
There is no question that Bluetooth products are primed to take the communication and consumer markets by storm. But to make these products a reality, designers must develop systems that achieve the performance, battery-life, and price demands of modern end users. Through proper testing, developers of Bluetooth systems can detect problems earlier in the design process and develop products that will succeed in the communication market.
