5. Zoom in and out to illustrate how th e center knob works. End in a spot where you are zoomed in on a single burst o f clocks.
Notice that you do no t have to turn a horizontal position control many times to move the zoom window to the beginning of the
acquisition, nor do you have to zoom way back out so you could move the window quickly, and then zoom back in when you
arrived at the new location. This is where the Tektronix 4000 Series pan function helps.
6. Turn the pan (outer) knob counterclockwise
a bit. N otice the extremely intuitive nature
of the zoom/pan controls.
Counterclockwise turning moves the
zoom box left.
Clockwise turning moves the zoom box
right.
The further you turn the pan knob, the
faster the zoom box moves.
You can move from one end of the
acquisition to the other end in a couple
of seco nds even with a 10 M record
length!
