Waveform Type

awg.set_waveform(waveform)  # Set waveform: SIN, SQU, TRI, RAMP

awg.set_square()            # Set to square wave
awg.set_triangle()          # Set to triangle wave
awg.set_ramp()              # Set to ramp wave

Example:

awg.set_sine()              # sine wave
awg.set_frequency(1000)
awg.set_amplitude(5.0)

Phase

awg.set_phase(phase)    # Set phase in degrees
awg.get_phase()         # Get phase in degrees

Example:

awg.set_phase(45)       # 45 degree phase shift

Duty Cycle (for square waves)

awg.set_duty_cycle(duty)  # Set duty cycle (0-100%)
awg.get_duty_cycle()      # Get duty cycle

Example:

awg.set_square()
awg.set_duty_cycle(75)    # 75% duty cycle

Burst Mode

awg.enable_burst()            # Enable burst mode
awg.disable_burst()           # Disable burst mode
awg.set_burst_mode(mode)      # Set burst mode: TRIGgered or MANUAL
awg.get_burst_mode()          # Get burst mode
awg.set_burst_cycles(cycles)  # Set number of cycles per burst
awg.get_burst_cycles()        # Get burst cycle count
awg.trigger_burst()           # Trigger a burst
awg.trigger()                 # Alias for trigger_burst()

Example:

awg.enable_burst()
awg.set_burst_mode("TRIGgered")
awg.set_burst_cycles(10)      # 10 cycles per burst
awg.trigger()                 # Fire one burst

Device Info

awg.get_id()              # Get device identification (*IDN?)
awg.is_connected()        # Check if device is reachable

Notes

• The driver is designed to be blocking and safe (no polling loops)
• Connection issues trigger automatic reconnection
• All socket operations include timeout handling
• DC offset is useful for biasing signals (e.g., for AC coupling)
• Burst mode allows generation of a finite number of waveform cycles triggered by command or external signal
