n1081b-sdk 1.0.3

N1081B Python SDK - WebSocket-based control library for the Nuclear Instruments N1081B logic unit

N1081B Python SDK

Python client library to control the Nuclear Instruments N1081B programmable logic unit over a WebSocket interface.

It provides a typed API to:

• configure and read back all available functions:

  • Logic functions: Wire, AND, OR, OR-Veto, Veto, Majority, Coincidence Gate, LUT
  • Counting and timing: Scaler, Counter, Counter/Timer, Chronometer, Rate Meter, Rate Meter Advanced
  • Time measurement: Time Tag, Time of Flight, Time over Threshold
  • Signal generation: Pulse Generator, Digital Generator, Pattern Generator

• Acquisition control (start/stop/reset) and result readout for all function types that support it

• Input/output configuration per section: signal standard and impedance

• Input configuration per channel: input enable, gate, delay and signal inversion

• Output configuration per channel: output enable, monostable and signal inversion

• Logic analyser: configuration and status readout for all input and output channels

• System settings: ethernet, clock and configuration file management

It is also possible to set and get the input and output sections and channels configuration parameters.

It implements the logic analyser configuration and data retrieval to acquire the logic status of all input and output channels.

Ethernet, clock and configuration file settings can also be managed through the SDK.

Features

• Simple WebSocket connection handling (connect/disconnect/login, password change)
• Enumerations for all categorical parameters (sections, function types, signal standards, impedance, etc.)
• High-level configuration helpers for each function type, for input/output sections and channels, for the logic analyzer and for the settings management

Quick start

Minimal example showing how to connect to a board, configure a section and start acquisition.

from n1081b_sdk import N1081B

# 1. Create device object and connect
device = N1081B("192.168.0.10")
device.connect()

# 2. Login with default password
if not device.login("password"):
    raise RuntimeError("Login failed")

# 3. Configure input of section A in NIM standard
device.set_input_configuration(N1081B.Section.SEC_A, 
                               N1081B.SignalStandard.STANDARD_NIM,
                               N1081B.SignalStandard.STANDARD_NIM,
                               0, N1081B.SignalImpedance.IMPEDANCE_50)

# 4. Configure section A as a scaler
device.set_section_function(N1081B.Section.SEC_A, N1081B.FunctionType.FN_SCALER)

# 5. Configure scaler enabling all four input channels and the input gate
device.configure_scaler(N1081B.Section.SEC_A, True, True, True, True, True)

# 6. Read results
data = device.get_function_results(N1081B.Section.SEC_A)
print(data)

# 7. Disconnect
device.disconnect()

See the examples/ directory for fully worked demos of each function type.
