Digital oscilloscope comprising multiple data acquisition pathways

A system, comprising:

• a first sampling unit configured to sample an input signal received from an oscilloscope probe to produce a first stream of digital samples;
• an acquisition system configured to store and process the first stream of digital samples;
• a second sampling unit configured to downsample the first stream of digital samples to produce a second stream of digital samples;
• and
• a display system configured to display the first stream of digital samples as a voltage waveform and concurrently display the second stream of digital samples in a numerical format, the first stream of digital samples, and the second stream of digital samples not being stored by a memory external to the acquisition system.

A system, comprising:

• a first sampling unit configured to sample an input signal received from an oscilloscope probe to produce a first stream of digital samples;
• an acquisition system configured to store and process the first stream of digital samples;
• a second sampling unit configured to downsample the first stream of digital samples to produce a second stream of digital samples;
• a controller configured to determine minimum and maximum values of the second stream of digital samples over a window of time;
• and
• a display system configured to present a bar graph indicating the minimum and maximum values, the first stream of digital samples, and the second stream of digital samples not being stored by a memory external to the acquisition system.
