Square: Produces a signal that alternates between two voltage levels with abrupt transitions. Suitable for digital circuits and timing tests.
Triangular: Produces a signal with a linear increase or decrease in voltage over time before the cycle repeats. It is used in scanning, timing, and system control.
Pulse: Produces short pulses with adjustable amplitude and duration. Useful for testing digital circuits and analyzing system response.
Arbitrary: Allows the creation or loading of custom waveforms beyond the predefined signal shapes. Suitable for specialized measurements and simulations.
Amplitude (AM): Information is transmitted by varying the amplitude (intensity) of the carrier signal while the frequency remains constant. It is used in RF applications and communications testing.
Frequency (FM): The information is transmitted by varying the frequency of the carrier signal. It offers greater noise resistance compared to AM.
Phase (PM): The information is transmitted through changes in the phase of the carrier signal. It is used in telecommunications and digital transmission systems.
Pulse Width (PWM): The information is encoded by changing the pulse duration (duty cycle) while the amplitude remains constant. Common in power electronics and motor control.
Frequency Shift Keying (FSK): Digital modulation where different frequencies correspond to different digital values (e.g., 0 and 1). Used in modems and wireless communications.
Amplitude Shift Keying (ASK): Digital modulation where the information is represented by changes in the signal amplitude. Used in simple data transmission systems.
Phase Shift Keying (PSK): Digital modulation where data is encoded by changes in the signal’s phase. Common in modern networks and wireless communications.
