f3ts-hardware-utils

f3ts-hardware-utils provides a consistent Python interface for controlling test instrumentation. Whether you're working with power supplies, DMMs, oscilloscopes, or other equipment, the library abstracts vendor-specific protocols behind a unified API.

Supported Instruments#

The library includes drivers for common test equipment:

Power Supplies

• Keysight E36xx series
• Rigol DP800 series
• Siglent SPD3303X

Digital Multimeters

• Keysight 34460A/34461A/34465A
• Fluke 8845A/8846A
• Rigol DM3000 series

Other Equipment

• USB-GPIO adapters (FT232H, MCP2221)
• Serial relay controllers
• Custom SCPI instruments

Quick Start#

pip install f3ts-hardware-utils

Basic usage:

from f3ts_hardware_utils import PowerSupply, DMM
 
# Connect to instruments
ps = PowerSupply.connect("TCPIP0::192.168.1.100::INSTR")
dmm = DMM.connect("USB0::0x2A8D::0x0101::MY12345678::INSTR")
 
# Unified API regardless of vendor
ps.set_voltage(3.3)
ps.set_current_limit(0.5)
ps.enable_output()
 
voltage = dmm.measure_voltage()
print(f"Output voltage: {voltage:.3f}V")

Why f3ts-hardware-utils?#

Direct VISA/SCPI programming requires dealing with vendor-specific command sets, connection handling, and error recovery. f3ts-hardware-utils handles these details:

• Consistent method names across vendors (set_voltage(), not VOLT:LEV 3.3)
• Automatic connection management including reconnection after power cycles
• Type safety with proper Python types instead of string parsing
• Error handling that translates instrument errors to Python exceptions

Integration#

f3ts-hardware-utils integrates seamlessly with pytest-f3ts for test automation, but works equally well standalone for scripting and interactive use.
