Consumer products like PDA s, automobiles, and appliances all contain microcontrollers, battery management, and power chips ; these can be mixed - signal devices. They use broadband products such as set - top boxes, cable modems, DSL, and DVD players that contain mixed - signal devices. Wireless products, cordless phones, cellular phones, WLAN, Bluetooth, GPS receivers, and cable tuners also contain mixed - signal SOC devices. The content of the mixed - signal SOC device is characterized by different types of cores. They may be analog cores or digital cores. Many applications include mixed analog and digital cores such as digital - to - analog converters (DAC s) and analog - to - digital converters (ADC s). These devices can provide complete system functionality on a single chip. One of the important principles to improving test economics is to ensure that test times are as low as possible. When testing, it is important that the test system is not adding overhead time. Beyond fast test software, the device - limited test speed is approached when tester operations execute in parallel with device operation. The architecture of the test system is key when approaching test times that are device limited. This can be achieved with a test system architecture that controls instrumentation precisely in device clock time. Mixed - signal device testing has adopted the use of DSP techniques to obtain a set of test measurements from large data sets. Each core within the device can produce data simultaneously. In the case of the device described earlier, there may be three video converters and five audio converters, all producing large amounts of data.
