Abstract
A measurement apparatus is provided for measuring signals from a device under test (DUT). The measurement apparatus includes a time domain receiver configured to receive from the DUT a time domain signal in a time domain; a logic domain receiver configured to receive from the DUT a logical signal comprising logic levels over time; a frequency domain receiver configured to receive from the DUT a frequency domain signal in a frequency domain through frequency downconversion; and a controller coupled to the logic domain receiver, and configured to determine the logic levels over time of the logical signal and to control at least one parameter of the frequency domain signal in response to the determined logic levels.
