Other measurements

+PulseCount : The number of positive pulses that rise above the

mid reference crossing in the waveform.

-PulseCount

: The number of negative pulses that fall below the

mid reference crossing in the waveform.

RiseEdgeCnt

: The number of positive transitions from the low

reference value to the high reference value in the waveform.

FallEdgeCnt

: The number of negative transitions from the high

reference value to the low reference value in the waveform.

Area : The area of the whole waveform within the screen and the

unit is voltage-second. The area measured above the zero reference

(namely the vertical offset) is positive; the area measured below the zero

reference is negative. The area measured is the algebraic sum of the area

of the whole waveform within the screen.

Cycle Area : The area of the first period of waveform on the screen

and the unit is voltage-second. The area above the zero reference (namely

the vertical offset) is positive and the area below the zero reference is

negative. The area measured is the algebraic sum of the area of the whole

period waveform.

Note: When the waveform on the screen is less than a period, the period

area measured is 0.

Customize an Automatic Measurement

You can customize automatic measurements by using gating and statistics.

Gating

 Press the Measure button, and the automatic measurement function menu

is displayed at the bottom of the screen;

 Press the Set softkey at the bottom of the screen, the setting menu

appears on the right side of the screen;

 Select the Gating menu. There are two menus: Screen and Cursor under

the range. Click the Screen and then click the Cursor, or press the right
