Operator’s Manual Simple AFG Application
42
The output signal levels displayed by the Simple AFG UI text are calculated for the specified source and
load impedances that by default are 50 Ohm. To change the expected load and source impedance
please refer to the Channel Settings.
Amplitude
The amplitude can be represented in three different formats that can be selected by opening the menu
beside the amplitude label:
•
Vpp (Peak to Peak Voltage):
it is the difference between the highest and lowest level of the
waveform.
•
Vrms (Root Mean Square Voltage):
it is the rms value of the waveform.
•
dBm:
it is the power transferred to the load expressed in dBmW (this representation is available
only for sine wave). Its value takes into account the Load impedance parameter specified in
Channel Settings.
Note:
The Vrms and the dBm values set in the textbox are referred only to the waveform amplitude.
T
hey don’t
take into consideration the Offset of the waveform.
Offset[V]
It defines the voltage
of “(Vmax + Vmin) / 2” expressed in Volts where Vmax is the maximum level of the
waveform and Vmin is the minimum level of the waveform
High Level [V]
It defines the maximum level of the waveform expressed in Volts
Low Level [V]
It defines the minimum level of the waveform expressed in Volts
