get_clock_mode() → ClockMode

# PSRC:CLOCkmode
value: enums.ClockMode = driver.psrc.get_clock_mode()

Sets the dependency of the pulse clock on the instrument’s reference clock.

Returns:

clock_mode: LOCKed | FREerunning

• LOCKed: The pulse source is locked to the reference clock of the instrument.

• FREerunning: The clock of the pulse source is independent. Deviations of the system do not affect the pulse clock, and deterministic conditions are avoided.

get_duty_cycle() → float

# PSRC:DUTYcycle
value: float = driver.psrc.get_duty_cycle()

Sets the duty cycle of the pulse, which is the ratio of the positive pulse width to the period of the signal.

Returns:

duty_cycle: For repetition rates 5 MHz, the value is fixed at 50 %.

get_output_low() → float

# PSRC:OUTPutlow
value: float = driver.psrc.get_output_low()

Sets the low level of the output pulse.

Returns:

output_low_level: -0.2 to -0.05

get_rep_rate() → float

# PSRC:REPRate
value: float = driver.psrc.get_rep_rate()

Sets the pulse frequency, the repetition rate of the pulse.

Returns:

repetition_rate: Available values depend on the selected clock mode: Locked: 5/10/20/50/100/200/500 Hz, 1/5/10/25/50/100/250 MHz Free running: 5/10/20/50/100/200/500 Hz, 1/5/10/25/50 MHz

get_state() → bool

# PSRC[:STATe]
value: bool = driver.psrc.get_state()

Switches the pulse output on and off.

Returns:

state: OFF | ON

set_clock_mode(clock_mode: ClockMode) → None

# PSRC:CLOCkmode
driver.psrc.set_clock_mode(clock_mode = enums.ClockMode.FREerunning)

Sets the dependency of the pulse clock on the instrument’s reference clock.

Parameters:

clock_mode –

LOCKed | FREerunning

• LOCKed: The pulse source is locked to the reference clock of the instrument.

• FREerunning: The clock of the pulse source is independent. Deviations of the system do not affect the pulse clock, and deterministic conditions are avoided.

set_duty_cycle(duty_cycle: float) → None

# PSRC:DUTYcycle
driver.psrc.set_duty_cycle(duty_cycle = 1.0)

Sets the duty cycle of the pulse, which is the ratio of the positive pulse width to the period of the signal.

Parameters:

duty_cycle – For repetition rates 5 MHz, the value is fixed at 50 %.

set_output_low(output_low_level: float) → None

# PSRC:OUTPutlow
driver.psrc.set_output_low(output_low_level = 1.0)

Sets the low level of the output pulse.

Parameters:

output_low_level – -0.2 to -0.05

set_rep_rate(repetition_rate: float) → None

# PSRC:REPRate
driver.psrc.set_rep_rate(repetition_rate = 1.0)

Sets the pulse frequency, the repetition rate of the pulse.

Parameters:

repetition_rate – Available values depend on the selected clock mode: Locked: 5/10/20/50/100/200/500 Hz, 1/5/10/25/50/100/250 MHz Free running: 5/10/20/50/100/200/500 Hz, 1/5/10/25/50 MHz

set_state(state: bool) → None

# PSRC[:STATe]
driver.psrc.set_state(state = False)

Switches the pulse output on and off.

Parameters:

state – OFF | ON
