WeeLab 0.1.4

Unified control library for lab equipment (oscilloscopes, power supplies, lasers, etc.)

Weeroc Lab Devices Package

This is an attempt to make a single python package containing all the tools for controlling the lab equipment as simply as possible.

Install

PyPI

To install the package use pip install WeeLab

Currently available devices

• CAEN A7585 SiPM power supply (device tested)

  from WeeLab import SerialConnection, CAEN_A7585
  caen = CAEN_A7585(
      conn=SerialConnection(port="COM6", baudrate=115200))
  caen.set_voltage(30)  # Set voltage to 30V
  caen.wait_setpoint_reached()  # Wait until the setpoint is reached
  caen.get_IV()  # Get the current and voltage values
  

• Lecroy WaveRunner (device tested)

  from WeeLab import Vxi11Connection, LeCroyWaveRunner
  lecroy = LeCroyWaveRunner(conn=Vxi11Connection(ip="192.168.2.21"))
  p1_mean = lecroy.getMeasure(1, "MEAN") # Returns mean value of P1 measurement 
  lecroy.clear_sweeps() # Clear sweeps
  

• NKT Pilas Laser (device tested)

  from WeeLab import SerialConnection, NktPilasLaser
  laser = NktPilasLaser(
      conn=SerialConnection(port="COM6", baudrate=19200))
  laser.set_tune(500) # Sets tune 50%
  laser.set_frequency(20_000_00) # Sets frequency 20 MHz
  laser.enable() # Enables radiation
  

• Keithley 2100 digital multimeter (device tested)

  from WeeLab import KeithleyMultimetre, VisaConnection
  keithley = KeithleyMultimetre(
      conn=VisaConnection(resource_name='USB0::0x05E6::0x2100::8012509::INSTR'))
  keithley.configure_voltage(0.001, 0.001) # Configures voltage measurement with 1 mV range and 1 mV resolution
  keithley.configure_current(0.001, 0.001) # Configures current measurement with 1 mA range and 1 mA resolution
  keithley.set_sample_count(100)      # Collect 100 samples per measurement
  current = keithley.get_current()    # Get an average current from samples
  voltage = keithley.get_voltage()    # Get an average voltage from samples
  

• Tektronix AWG generator (test TODO)

  from WeeLab import VisaConnection, Tektronix_AFG3252
  afg = Tektronix_AFG3252(
      conn=VisaConnection("USB0::0x0699::0x0345::C010630::INSTR"))
  afg.do_set_voltage_ch1(5) # Sets voltage on ch1 to 5 V
  afg.set_frequency_ch1(10_000) # Sets frequency 10 kHz
  afg.do_set_status_ch1("on") # Enables generation in ch1
  

• WeeMove translation stage (test TODO)

  from WeeLab import SerialConnection, Stage
  stage = Stage(
      conn=SerialConnection(port="COM4", baudrate=9600))
  stage.move(10, 20) # Moves to x=10cm, y=20cm
  stage.wait_arrived() # Waits until the stage is no longer moving
  stage.ask_position() # Prints current position
