Amplitude Modulation (AM) and Frequency Modulation (FM)
l SCPI: [SOURce[1|2]:]FREQuency {<frequency>|MIN|MAX}
The APPLy command configures a waveform with one command.
Modulating Waveform Shape
The instrument accepts an internal or external AM or FM modulation source. On a two-channel instrument you can
modulate one channel with the other.
You cannot modulate noise with noise, PRBS with PRBS, or an arbitrary waveform with an arbitrary
waveform.
l The modulating waveform shape (internal source) may be:
l Sine wave
l
Square with 50% duty cycle
l
UpRamp with 100% symmetry
l
Triangle with 50% symmetry
l
DnRamp with 0% symmetry
l Noise - white gaussian noise
l PRBS - Pseudo Random Bit Sequence (polynomial PN7)
l Arb - Arbitrary waveform
l Front Panel:
or
Then choose the modulating shape:
