Flann Programmable Device's Python Libary

drawing

Description

Python libary to connect to Flann's programmable instruments and standardise the command structure.

Home Page

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

from flann.vi.switch import Switch337
switch_box1 = Switch337(switch=1, address='COM5', timedelay=0.3, timeout=0, baudrate=31250)
switch_box1.toggle_all()  # Toggle all switches connected to the switch-box
switch_box1.switch = 2  # Selecting switch 2
switch_box1.position1()  # Switching switch 2 to position 1
from flann.vi.attenuator import Attenuator024
atten = Attenuator024(address='COM3', timedelay=0.1, timeout=0.44, baudrate=31250)
print(atten.id())  # Prints the identification of the attenuator
atten.attenuation = 20.5  # Sets the attenuation to 20.5 dB
print(atten.attenuation())  # get the current attenuation value
from flann.vi.attenuator import Attenuator625
atten = Attenuator625(address='10.1.4.4', timedelay=0.1, tcp_port=10001)
print(atten.id())  # Prints the identification of the attenuator
atten.position = 500  # Sets the position to 500 steps
print(atten.position())  # get the current position steps value
