ekpy.control.instruments.berkeleynucleonics765.core.clear_errors(pg, max_iterations: int = 10)
ekpy.control.instruments.berkeleynucleonics765.core.get_pulse_mode(pg, channel: str)

Return ‘single’, ‘double’, ‘triple’, ‘quadruple’

ekpy.control.instruments.berkeleynucleonics765.core.initialize_2pulse(pg, polarity='up', channel='1', pulsewidth='10e-9', delay='10e-9', low_voltage='0', high_voltage='4.8')

Initialize BN765 for application of 2 pulse sequence. Pulses are positive polarity, and identical (as defined by low and high voltage) with given delay between pulses.

Parameters

  • pg – (pyvisa.resources.ENET-Serial INSTR): BN765

  • channel (str) – Specify output channel. ‘1’ or ‘2’.

  • pulsewidth (str) – Pulsewidth in scientific notation.

  • delay (str) – Delay between pulses in scientific notation.

  • low_voltage (str) – Low voltage in units of volts.

  • high_voltage (str) – High voltage in units of volts.

ekpy.control.instruments.berkeleynucleonics765.core.initialize_pulse(inst, channel='1', *args, **kwargs)

Initializes the pulse generator for application of a single pulse which will output a pulse on manual trigger.

Parameters

  • inst (pyvisa.resources.ENET-Serial INSTR) – Berkeley Nucleonics 765

  • channel (str) – Output channel.

ekpy.control.instruments.berkeleynucleonics765.core.initialize_trig(pg, pulsen, channel='2', pulsewidth='10e-9', delay='10e-9', low_voltage='0', high_voltage='1')

Initialize a channel for use as a trigger. This is used in conjunction with, for example, initialize_2pulse, so we can output a trigger pulse from the other channel in order to properly time the scope for acquisition. We can do this for any of the pulse n (in the case of 2 pulses one can send a trigger pulse synced to pulse 1 or 2).

Parameters

  • pg (pyvisa.resources.ENET-Serial INSTR) – BN765

  • pulsen (int) – Specify which pulse number to ready a trigger pulse (1 or 2)

  • channel (str) – Specify a channel for trigger output.

  • pulsewidth (str) – Pulsewidth of the triggr pulse in scientific notation. This should match your stimulus pulsewidth.

  • delay (str) – Delay in scientific notation. This should match your stimulus delay.

  • low_voltage (str) – Low voltage of trigger pulse in Volts.

  • high_voltage (str) – High voltage of trigger pulse in Volts.

ekpy.control.instruments.berkeleynucleonics765.core.manual_trigger(pg)

Trigger BN765 to apply whatever pulse configuration is set.

ekpy.control.instruments.berkeleynucleonics765.core.single_pulse_SCPI(pulsewidth, updown, high_voltage, low_voltage, channel='1', *args, **kwargs)

Returns SCPI string that can be written to the pulse generator to put it in the correct state to apply a single pulse.

Parameters

  • updown (str) – Specify polarity. ‘up’ or ‘down’.

  • high_voltage (str) – High voltage of pulse. i.e. ‘1000mv’ allowed units {V, mv}

  • low_voltage (str) – Low voltage of pulse. i.e. ‘-1000mv’ allowed units {V, mv}

ekpy.control.instruments.berkeleynucleonics765.core.symmetric_up_down_SCPI(pulsewidth, amplitude, offset='0mv', channel='1', *args, **kwargs)

Return a tuple of two SCPI strings. The first, an up SCPI string (from single_pulse_SCPI) and the second down. The strings describe symmetric pulses.

Parameters

  • amplitude (str) – Amplitude. allowed units {mv, v}.

  • offset (str) – Offset. allowed units {mv, v}.
