Fig. 9.4: Entering constants and units
word will be shown with a blue background). In this menu you
have the opportunity to display the equations, to add physical
units (e.g. A) and to attribute names.
In Fig. 9.4, in formula MA1, a current of 100 µA is added to the
channel 1. In the menu for entering constants it is possible to
choose from the following list of constants, executed by pushing
the key CONSTANT and turning the universal knob:
– Pi
– 2x Pi
– 0,5 x Pi
– User 1 . . . 10
(there are up to 10 user dened constants possible)
If e.g.  is selected, it is possible to set the value with
the universal knob after pushing the menu key next to .
Following the same procedure the decimal point and a possible
SI-prex can be set. The following SI-prexes are available:
– m (Milli, 10-3)
– µ (Mikro, 10-6)
– n (Nano 10-9)
– p (Piko, 10-12)
– f (Femto, 10-15)
– a (Atto, 10-18)
– z (Zepto 10-21)
– y (Yokto, 10-24)
The menu item  offers the following list of units, selectable
with the universal knob:
– V (Volts)
– A (Amperes)
– Ω (Ohms)
– V/A (Volts per Ampere)
– W (Watts,
active power)
– VA (Voltamps,
apparent power)
– VAr (Voltamps,
reactive power)
– dB (decibels)
– dBm (dB
referred to 1 mW)
– dBV (dB
referred to 1 V)
– s (Second)
– Hz (Hertz)
– F (Farad)
– H (Henry)
– % (Percent)
– º (Degree)
–
p (Pi)
– Pa (Pascal)
– m (Meter)
– g (Acceleration)
– ºC (Degrees Celsius)
– K (Kelvin)
– ºF (Degrees Fahrenheit)
– N (Newton)
– J (Joule)
– C (Coulomb)
– Wb (Weber)
– T (Tesla)
– (dez) (dezimal)
– (bin) (binary)
– (hex) (hexadezimal)
– (oct) (octal)
– DIV (Division, graticule)
– px (pixel)
– Bit (Bit)
– Bd (Baud)
– Sa (Sample)
– K (Kilo, 10

)
– M (Mega, 10
6
)
– G (Giga, 10

)
– T (Tera, 10
12
)
– P (Peta, 10
15
)
– E (Exa, 10
18
)
– Z (Zetta 10
21
)
– Y (Yotta, 10

After entering the value, the prex, the unit (or any combination)
push the soft menu key next to : now this will be stored at
the address , then the system will automatically return
to the menu for equations. It is possible to store up to 10 user
dened constants.
In this menu it is further possible to add a name to each of the
5 equations: in order to do this rst select the desired equation,
then push the lowest menu key , this will open a window.
Now the intended name (up to 8 characters) can be dened with
the universal knob after pushing the CURSOR SELECT key; the
name will be accepted after pushing the soft menu key next
to  and displayed in place of MA1 ... MA5. This may be
done separately for all equations. After entering all equations,
constants and names it is possible to also add a name for this
set of formulas by pushing the key next to  in the set of
formulas menu and following the above procedure again. The
completed set of formulas may be stored in the instrument or
on a USB stick. In order to do this push the key next to , a
menu will open which allows you to select the storage medium
by pushing the top menu key (internal, USB front panel, USB
rear panel). The menu item below offers to add a name for the
set of formulas. A commentary can be added by pushing the key
next to . By pushing the key next to  the set
of formulas together with the name chosen and a commentary
will be stored in the selected location.
Stored sets of formulas may be recalled any time. In order to
do this activate the mathematics by pushing the key MATH and
then the key MENU and the V/DIV knob. A menu item 
will appear in this menu. By choosing this, the data control will
appear, showing the internal memory location, and, if an USB
stick is plugged in, also that location. Select the desired location
and push the key .
9.3 Frequencyanalysis(FFT)
The frequency analysis function will be called by pushing the
key FFT in the ANALYZE section of the front panel, the key will
light up white, the screen will be divided into two graticules. In
the upper smaller area, the signal will be displayed vs. time,
in the lower, larger area the result of the FFT analysis will be
shown. The lower FFT display window will be framed in white.
This means that the large knob in the time base area is now
dedicated to selecting the span, and that the small knob X PO-
SITION to setting the CENTER position.
