5. HOW ARE WAVEFORMS DISPLAYED?
5.1 "Manual" display
To view the signal and project it on the screen, you must know (or imagine), as prerequisites, the following characteristics:
 the coupling  whether the signal is pure AC or has a DC component,
 the amplitude in Volts  to define its amplitude on screen,
 the frequency or period of the signal  if it is repetitive,
 the bandwidth  the frequency entails.
Once these data are known, the parameterizing of the channel to display the signal can begin. There are two ways to
parameterize the channel:
using the keypad
using the touch screen
5.1.1. Using the keypad
Key  Action 
1. Connect the Probix probe to the input of a channel.
2. Press the key of the channel to refresh it and access parameterizing.
3. Pressing this key selects the desired coupling.
4. This key selects the desired vertical sensitivity of the channel or its maximum amplitude
visible on screen.
5. This key selects the desired time base of the channel or the maximum period visible on
screen.
6. Press the key opposite.
7. The signal appears.

Note
It is not possible to parameterize the bandwidth of the signal from the keypad.
