A quick introduction

Your oscilloscope offers these possibilities:

 

❙ the definition of the display of 6 parameters which may 

come from different sources

 

a quick view of all important parameters of one source 
using the Quick View function.

Please change the time base to 100 µs per scale division 
and press the QUICKVIEW 

10

 key. You will see the follow-

ing display:

The following list features the most important parameters 
of a signal:

 

❙ positive and negative peak voltages,

 

❙ rise and fall times, 

 

mean voltage.

10 additional parameters are shown below the grid:

 

❙ RMS,  

  peak-peak voltage,

 

❙ frequency,  

 

period,

 

❙ amplitude,  

  number of rising edges,

 

pos. 

pulse width,  

 neg. 

pulse width,

 

pos. 

duty cycle,  

 neg. duty cycle.

Thus by simply pressing a key you see 14 parameters at a 

glance which characterize the signal. This function applies 

always to the acutal active channel.

You see now a two-window 

display: the display will show 
in the top area the complete 

captured signal, below an en-

larged portion. Use the time 
base knob to select the 

zoom 

factor and the small knob for 

horizontal positioning.

By pressing the ZOOM key 

40

 

again the 

zoom mode be will 

be deactivated.

3 .4  Cursor measurements

After displaying the signal and its details we now proceed 
to measuring it using the cursor functions. Press again 
shortly AUTOSET 

15

 and then the CURSOR/MEASURE key 

8

. Now the cursor menu will open up, and you can se-

lect the kind of cursor. Press the top soft key in order to 
open the appropriate menu. Use the knob in the CURSOR/

MENU area for the selection by turning it CCW until the V-
marker is underlined, press the universal button or wait for 

some seconds in order to accept the selection. Now two 

cursors will be displayed along with the signal, and the 

measurement results in the bottom area of the grid. Select 
the active cursor by pushing the universal knob and posi

-

tion it by turning the knob.

The cursor measurement results will be displayed at the 
bottom of the 

grid. In this case the V-marker has selec-

ted the voltages at the two cursor positions, their diffe-
rence, and the time difference between the positions will 

be shown. The cursors will be switched off by pressing the 
CURSOR/MEASURE key and the associated Cursors off 
soft key. 

3 .5  Automatic measurements

In addition to cursor measurements the most important 
signal parameters can be displayed.
