3.5 Automatic Measurements

In addition to cursor measurements the most important si-

gnal parameters can be displayed. Your oscilloscope offers

these possibilities:

❙ Displaydenitionof6parametersfromvaryingsources

❙ Quick display of all important parameters of one source

by use of the QUICK VIEW feature

Please change the time base to 100 µs per scale division

and press the QuickView

key. You will see the most im-

portant parameters of a signal displayed:

❙ 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.

With just one key, you can view all available parameters si-

multaneously that characterize the signal. This feature al-

ways applies to the currently active display channel. You

may also display parameters for several signals. For this

3.4 Cursor Measurements

After displaying and reviewing the signal, the next step

will introduce cursor measurements of the signal. Again,

brieypresstheAUTOSETkeyoncefollowedbytheCUR-

SOR/MEASURE key. You can now select the desired type

of measurement cursor from the menu. Press the soft

menu key MEASURE TYPE to open the appropriate selec-

tion menu. You can specify your selection with the uni-

versal knob in the CURSOR/MENU section of the con-

trol panel. Turn the knob CCW until the entry V MAR-

KER is marked in blue. Press the MENU OFF key to close

the menu or wait until it automatically closes after a few

seconds.

Now two cursors will be shown along the signal as well

as the measurement results on the bottom of the display.

Press the universal knob to select the active cursor and

turn the universal knob to position the cursor. The cursor

measurement results will be shown on the bottom of the

display. In this example with the entry “V marker”, the dis-

play includes the voltage at both cursor positions, their dif-

ference, and the time difference between the cursor posi-

tions. To switch off the cursor, press the CURSOR MEA-

SURE key again.
