Example 2: Multiple Waveforms
In this example you learn how to display and control more than one waveform
at a time.
The VERTICAL section of the front panel contains the channel selection
buttons. These are CH 1, CH 2, CH 3, CH 4, and MORE (Figure 1-13); on the
TDS 620A & 524A, they are CH 1, CH 2, AUX 1, AUX 2, and MORE.
Figure 1-13: The Channel Buttons and Lights
Each of the channel (CH) buttons has a light above its label. Right now, the
CH 1 light is on. That light indicates that the vertical controls are set to adjust
channel 1.
