Scientific instruments from manufacturers like National Instruments or older HP/Agilent gear often required a specific emulation layer to interpret raw sensor data. Sentemul 64 bit provides the glue between antique GPIB controllers and modern data science environments like Python (via ctypes) or MATLAB.
