Features to Try - Vectors:

The 54622D oscilloscope is a digital instrument that makes a graph of voltage versus time by

putting individual dots on the screen. By contrast, an analog ‘scope creates a graph which is

continuous (no dots are used).

Each dot represents an (x,y) pair (time, voltage) in a Cartesian coordinate system. If the

dots are close together, your eyes are fooled and you see a continuous line; if the dots are too

far apart, you’ll see individual dots. To overcome the problem of seeing dots, a Vectors mode

can be used which “connects the dots”. This can be seen very clearly as follows.

YOU DO IT:

1) Press the Run/Stop button, so that it changes from green (Run) to red (stop). The

waveform displayed, and its dots, are now frozen in memory.

2) Change the Time/Div from 200 us/div to 20 ns/div. You should see the display below

(Vectors turned ON).

3) Now press the Display hardkey (in the Waveform section), and press the Vectors

softkey. Now the display (Vectors turned OFF) should appear. The individual dots

are very apparent, and this is not as “pleasing” a display. Normally, Vectors can be

left ON.
