3.5 Automaticmeasurements
In addition to cursor measurements the most important signal
parameters can be displayed. Your HAMEG oscilloscope offers
these possibilities:
– the denition of the display of 2 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 now to 100 µs/div. and press the
QUICK VIEW key

Fig. 3.8: Quick View parameter measurement
Here you see the most important parameters of a signal dis-
played:
– positive and negative – rise and fall times
peak voltages – mean voltage
In the right bottom corner of the screen 4 more parameters
are shown:
– rms value – peak-to-peak voltage
– frequency – period
Thus by simply pressing a key you see 9 parameters at a glance
which characterize the signal. This function applies always to
the acutal active channel.
You may also display two parameters of two different signals. In
order to achieve this deactivate the QUICK VIEW function by pres-
sing the key again, then activate channel 2 by pressing the CH2
key. Open the following menu by pressing AUTOMEASURE

menu
The two parameters are displayed in the right bottom corner of
the screen. You may dene the parameter measurement using
this menu. After switching on  and  with
the appropriate softkey’s the parameter measurements are
displayed in the right bottom corner of the screen. If you press
the softkey beside  you can choose the parameter you want
from the list using the general knob. This procedure is used in
all menus where choices are available. Please press the key
 and choose risetime.
Fig. 3.10: Selection of parameters
Now use soft key next to   in order to select this menu
item and thus channel 2. Now the rise time of channel 1 and
the mean value of channel 2 are shown. After the menu has
been closed, the parameters can be identied by the colours
of the respective channels, (here yellow for channel 1 and
blue for channel 2.)

3.6 Mathematicalfunctions
In addition to cursor and parameter measurements your HMO
can also apply mathematical functions to the signals. By pres-
sing the MATH key a short menu will open which allows you to
select one or two predened mathematical functions. A quick
setting of mathematical functions is possible by selecting the
menu item at the bottom. This mode allows you to select the
addition or subtraction of two activated sources. The formula
editor allows to predene 5 possible mathematical functions,
it is called by pressing the MATH key (which lights up red) and
the MENU key
