AM Source
An internal and/or external source can be selected for amplitude modulation. Press
MOD
->
AM
->
AM Source
to set “Int” or “Ext” or “Int + Ext”. The default is “Int”.
1. Int
When internal modulation is selected, the AM Shape, AM frequency, and AM depth are
controlled by the instrument. The internal modulation setting uses the LF generator as the
modulation signal source. When modulation is activated, the LF output will be disabled, if it
was previously activated.
2. Ext
Use an external modulation signal. The external signal is input via the
[EXT MOD INPUT]
connector on the rear panel of the instrument. The modulated signal can be an arbitrary
waveform.
3. Int + Ext
Use both the internal and external modulation signals. This technique can be used to
source dual tone AM.
AM Shape
The SSG5000A
supports modulation waveforms for internal “Sine” and “Square”
modulation sources. Select
MOD
->
AM
->
AM Shape
, after setting
AM Source
to “Int” or
“Int+Ext”, you can select AM waveform as “Sine” or “Square”.
AM Rate
Select
MOD
->
AM
->
AM Rate
, and set the AM rate.
1. Sine wave modulation frequency range is 0.01Hz~100kHz
2. Square wave modulation frequency range is 0.01Hz~20kHz
