PSK
Keying rate
Same as ASK
Polarity
Positive phase/inverted phase. In positive phase, the phase is 0° when
varying from 0 to 1 and 180° when 1 to 0. Opposite when inverted
Application example: Generate an FM waveform with an internal modulation
source and the following parameters
Carrier waveform = Sine, frequency = 120 MHz
Modulating waveform = triangle, frequency = 1 MHz, frequency deviation = 10 MHz
1. Set "Waveform" of the carrier to Sine and "Frequency" to 120 MHz in the parameter
setting page of the carrier
2. Click on the settings icon in the Modulation/Sweep/Burst settings box at the
bottom left of the page to enter the interface for modulation/sweep/burst settings
3. Set "Mod" to "On"
4. Set " Type" to "FM"
5. Set "Source" to "Internal"
6. Set the "FM Freq" to 1 MHz
7. Set "Freq Dev" to 10 MHz
8. Set "Shape" to "Triangle"
9. Open the output
Follow the above steps to generate the desired FM waveform. The modulation parameters page
is as follows:
