Measurements

falling slope. The mean value is calculated from the ampli-
tude of the measurement signal. A slope will be counted if 
the signal runs through the mean value. A pulse that pas-
ses the mean value only once will not be calculated. The 
measurement will only be applied to the selected channel.

COUNT – :

 This mode counts negative pulses 

in the displayed view of the screen. A negative 
pulse consists of a falling slope followed by a 

rising slope. The mean value is calculated from the ampli-
tude of the measurement signal. A slope will be counted if 
the signal runs through the mean value. A pulse that pas-
ses the mean value only once will not be calculated. The 
measurement will only be applied to the selected channel.

COUNT +/ :

 This mode counts signal changes 

(slopes) from Low Level to High Level in the 
displayed view of the screen. The mean value is 

calculated from the amplitude of the measurement signal. 
A slope will be counted if the signal runs through the 
mean value. The measurement will only be applied to the 
selected channel.

COUNT –/ :

 This mode counts signal changes 

(slopes) from High Level to Low Level in the 
displayed view of the screen. The mean value is 

calculated from the amplitude of the measurement signal. 
A slope will be counted if the signal runs through the 
mean value. The measurement will only be applied to the 
selected channel.

TRIGGER FREQUENCY:

 This mode measures 

the frequency of the trigger signal bases on 
the period duration (f

Tr

). The source for the 

measurement is the currently set trigger source. The fre-
quency will be determined with a hardware counter with a 
high accuracy of 5 digits.

TRIGGER PERIOD:

 This mode measures the 

duration of periods of the trigger signal (with a 
hardware counter T

Tr

).

Fig. 8.2: Auto measurement setting menu

The automatic measurement results are displayed at the 
bottom of the screen. If “n/a” is displayed, the measurement 
is not applicable to the signal. For instance, this may be the 
case for a voltage measurement on a POD because only 
logic states without voltage reference are displayed here. If 
“?” is displayed, the display does not show a complete mea-
surement result. For instance, the period to be measured 
may not display completely and can consequently not be 

identified.

With the soft menu key CLEAR ALL the activated automa-
tic measurements will be switched off.

The list of available sources only includes displayed  
channels (possible sources are analog, digital and mathematical 
channels).
