Front Panel Controls (Keys and Knobs) Overview
The Infiniium 90000A Series oscilloscope front panel gives you direct access to the 
functions needed to perform the most common measurements, using a traditional 
oscilloscope interface. Knobs and keys let you directly set vertical and horizontal 
parameters. The front panel also has a set of LED indicators; by using these and 
the display, you see the oscilloscope’s configuration at a glance.
The oscilloscope uses color consistently throughout the front panel and user 
interface. For example, the color of the knob for channel 1 is the same color as the 
waveform for channel 1. All the configuration items and values related to channel 
1 are displayed in the same color.
