Setting the Signal Amplitude
Application
You cannot enter a voltage directly for user-defined waveforms. The scaling
is used to define the response to voltage. This represents the peak-to-peak
voltage V
pp
when the full digital value range (+2
13
to
-2
13
) is being used.
The following relationship applies:
V
pp
= V’pp * scaling
This means that a digital value of -2
13
(+2
13
) in the waveform memory at a
scaling of 3 V/Full Scale yields an output voltage of 3 V
pp
at 50
Ω
.
Waveform memory
Output voltage with
scaling = 3 V/Full Scale
Setting the
scaling
1.
In the
submenu
press the
function key
.
An entry field containing the current setting is displayed. The default
setting is 2 V FS (Full Scale).
2.
Enter a new value ( 5-55).
The permissible entry range for the scale factor is:
1 mV
≤
scaling
≤
10 V
in 0.1 mV steps
Level display
The new setting is stored and then displayed in the diagram area. The
divisions on the level axis (grid lines) change in accordance with the set
scaling.
