Amplitude Modulation (AM) and Frequency Modulation (FM)
Carrier Waveform Shape
AM or FM carrier shape: Sine (default), Square, Ramp, Pulse, Triangle, Noise, PRBS, or Arbitrary waveform. You can-
l
not use DC as the carrier waveform.
For FM, the carrier frequency must always be greater than or equal to the frequency deviation. Attempting to set a
l
deviation greater than the carrier frequency will cause the instrument to set the deviation equal to the carrier
frequency.
The carrier frequency plus the deviation cannot exceed the selected function's maximum frequency plus 100 kHz.
l
If you attempt to set the deviation to an invalid value, the instrument adjusts it to the maximum value allowed
with the present carrier frequency. The remote interface also generates a "Data out of range" error.
