Requirements for Testing Mixed-Signal Components
of an SOC Device
Testing a buffer To measure the characteristics of a buffer (such as an impedance
converter, amplifier, or attenuator), one needs to apply an analog
signal and analyze the analog response.
Testing a Buffer
Testing an ADC To measure the characteristics of an analog-to-digital converter,
one needs to apply an analog signal and analyze the digital
response.
Testing an ADC
Testing a DAC To measure the characteristics of a digital-to-analog converter, one
needs to apply a digital signal and analyze the analog response.
Testing a DAC
Summary:
For testing mixed-signal devices, one needs instruments which are
capable of applying analog and/or digital signals to the DUT and
analyzing analog and/or digital responses.
