R&S AM300
Arbitrary and Function Generator
Operating manual, 02/2005

E-1007.9922.12
Switching AM On/Off
Note
The amplitude that has been set and is displayed in the R&S AM300 applies
to the unmodulated carrier signal. If you switch on the amplitude modulation,
the carrier's output voltage is reduced automatically by half (6 dB). This
ensures that the max. permissible output voltage of the R&S AM300 is not
exceeded even at an amplitude modulation of 100 %.
Application
In order to activate AM modulation mode, you need to switch it on in the AM
MOD submenu.
Switching AM on
1.
In the
submenu
press the
function key
.
The function key is highlighted.
Display
The currently applicable AM modulation depth and frequency are
displayed in the parameter field below the respective channel name, e.g.
for CH1: "Mod: AM 100 %, Mod.Freq 100 Hz".
Note
: The waveform displayed beside the channel names is the
modulation carrier signal, e.g. "Sine, Freq: 1 kHz, Ampl: 2 V
pp
".
Switching AM off
2.
In the
submenu
press the
function key
.
The function key is
no longer
highlighted. Amplitude modulation is
switched off and the display disappears from the parameter field.
Note
To deliver the output signal to the output complete with all the functions and
parameters that have been set, you need to switch the channel on ( 6-143).
