Instruments

Software to control Flann's programmable instruments. These currently include:

• Attenuators

  • 024 variable attenuator
  • 624 programmable RVA (Rotary Vane Attenuators)
  • 625 programmable RVA (Rotary Vane Attenuators)

• Switch

  • 337 dual-switch controller
  • 338 POE switch

Examples

fromflann.vi.switchimportSwitch337switch_box1=Switch337(switch=1, address='COM5', timedelay=0.3, timeout=0, baudrate=31250)
switch_box1.toggle_all() # Toggle all switches connected to the switch-boxswitch_box1.switch=2# Selecting switch 2switch_box1.position1() # Switching switch 2 to position 1

fromflann.vi.attenuatorimportAttenuator024atten=Attenuator024(address='COM3', timedelay=0.1, timeout=0.44, baudrate=31250)
print(atten.id()) # Prints the identification of the attenuatoratten.attenuation=20.5# Sets the attenuation to 20.5 dBprint(atten.attenuation()) # get the current attenuation value

fromflann.vi.attenuatorimportAttenuator625atten=Attenuator625(address='10.1.4.4', timedelay=0.1, tcp_port=10001)
print(atten.id()) # Prints the identification of the attenuatoratten.position=500# Sets the position to 500 stepsprint(atten.position()) # get the current position steps value
