Abstract
An oscilloscope includes a time domain input, a logic domain input, and a frequency domain input. The time domain input provides a time domain input signal in a time domain as a first input signal. The logic domain input provides logic level input as a second input signal. The logic level input includes logic levels over time. The frequency domain input provides a third input signal through frequency downconversion.
Claims6
A measurement apparatus, comprising:
- a time domain receiver configured to receive a time domain input signal in a time domain;
- a logic domain receiver configured to receive a logical signal comprising logic levels over time;
- a frequency domain receiver configured to receive a frequency domain signal in a frequency domain through frequency downconversion;
- and
- a controller coupled to the logic domain receiver, and configured to control, based on logic levels of the logical signal over time, at least one parameter of the frequency domain signal,
- wherein the frequency domain receiver is further configured to receive the frequency domain signal at acquisition frequencies controlled by the controller in accordance with the logic levels of the logical signal.
