A PyVISA backend that implements a large part of the Virtual Instrument Software Architecture in pure Python (with the help of some nice cross platform libraries python packages!).Description. PyVISA started as wrapper for the IVI-VISA library and therefore you need to install a VISA library in your system (National Instruments, Keysight, etc) Pyvisa-py is available on PyPI and can be easily installed using pip: pip install pyvisa-py. Pyvisa-py runs on Python 3.6+. If you do not install any extra library pyvisa-py will only be able to access tcpip resources. The following sections will describe what extra libraries you need to install and how to configure them to use other resources

PyVISA is both a Python wrapper for VISA shared libraries but can also serve as a front-end for other VISA implementation such as PyVISA-Py. VISA and Python Python has a couple of features that make it very interesting for measurement controlling PyVISA: Control your instruments with Python¶. PyVISA is a Python package that enables you to control all kinds of measurement devices independently of the interface (e.g. GPIB, RS232, USB, Ethernet). As an example, reading self-identification from a Keithley Multimeter with GPIB number 12 is as easy as three lines of Python code

My code runs normal and as expected when I run it from the commandline using python3 mycode.py. But when I compile it using pyinstaller -w -F mycode.py the code takes forever to compile and when I run it going into ./dist/mycode i get an error: File pyvisa/highlevel.py, line 3015, in __new__ File pyvisa/highlevel.py, line 2924, in open_visa. import pyvisa rm = pyvisa.ResourceManager('@py') part of code as above, it works well with direct running *.py file, but it failed when package the *.py file to executable file with pyinstaller, the wrong message as below: ValueError: Wrapper not found: No package named pyvisa-py PyVISA-py implements the majority of the methods for Serial/USB/GPIB/Ethernet communication (SCPI), and is is used almost identical to the NI-VISA backend. Install using pip: pip install -U pyvisa pip install pyvisa-py. Keysight E5810B is a LAN/GPIB/USB gateway. It enables remote control of GPIB, USB and RS-232 instruments via LAN in a one-box.
