A Rigol oscilloscope has a USB output, allowing you to control it with a computer and and perform additional processing externally. I was inspired by Cibo Mahto's article Controlling a Rigol oscilloscope using Linux and Python, and came up with some new Python oscilloscope hacks: super-zoomable graphs, generating a spectrogram, analyzing an IR signal, and dumping an oscilloscope trace as a WAV. Use PyVISA to access a serial device. Normally I would use pyserial for this, but since I have a VISA dependency anyway, I prefer to minimize dependencies. Anyway, the following problem occurs on an 'openresource': Traceback (most recen. GPIB と USB は備えてるけど GPIB を Mac で動かすのは面倒だし、かつその USB は PySerial で動かないしなんて装置があった場合、PyVISA を使うという手があります。 あと、LAN 接続も可能な機種だと PyVXI11 を使ったりなんてのも可能です。ただ、環境によっては IP.

I tried shutting and re-instaIling driver for ReaItek PCLe FE family members Controller. So I wish to download a new windows 10 internet controller driver on another pc with internet access, and then exchange the document to the HP and instal the brand-new driver. I cannot believe that the driver is certainly 10 MB. Will be this accurate?
Realtek Usb Fe Driver
I down loaded 0019-InstallWin102017-1 Is usually this the correct driver? I put on't need to do anything else, download software that up-dates all my motorists etc etc. Just the internet comtroller driver. After installation of this Car owner (automatically with Home windows 10 up-date) I experienced lost instantly the LAN Connection.
What proved helpful for me: 1. Total deinstallation of thé Realtek PCle FE Family Controller in the Gadget Manager. Restarting the Personal computer. Installing the old Realtek PCIe FE Household Controller, Version 9.1.406.2015 from. My System: AMD Turion64 tl56 processor, Gain 10 Pro 64bit, AMD 690v/SB600 Chipset, Realtek PCIe FE Household Control, Qualcomm Atheros AR5007EG WLAN Adapter. Maybe this works for you, as well. At minimum: It´h worthy of a attempt.

Python VISA bindings for GPIB, RS232, and USB instruments
Project description
PyVISA-py
A PyVISA backend that implements a large part of the “Virtual Instrument SoftwareArchitecture” (VISA) in pure Python (with the help of some nice cross platformlibraries python packages!).
Description
PyVISA started as wrapper for the NI-VISA library and therefore you need to installNational Instruments VISA library in your system. This works most of the time,for most people. But NI-VISA is a proprietary library that only works on certainsystems. That is when PyVISA-py jumps in.
Starting from version 1.6, PyVISA allows to use different backends. These backends can bedynamically loaded. PyVISA-py is one of such backends. It implements most of the methodsfor Message Based communication (Serial/USB/GPIB/Ethernet) using Python and some well developed,easy to deploy and cross platform libraries
VISA and Python
Python has a couple of features that make it very interesting for measurement controlling:
- Python is an easy-to-learn scripting language with short development cycles.
- It represents a high abstraction level, which perfectly blends with the abstractionlevel of measurement programs.
- It has a very rich set of native libraries, including numerical and plotting modules fordata analysis and visualisation.
- A large set of books (in many languages) and on-line publications is available.
Requirements
- Python (tested with 2.7, 3.4+)
- PyVISA 1.6+
Optionally- PySerial (to interface with Serial instruments)- PyUSB (to interface with USB instruments)- linux-gpib (to interface with gpib instruments, only on linux)- gpib-ctypes (to interface with GPIB instruments on Windows and Linux, warning: experimental)
Python 2 support
With Python 2 EOL behind us, and given the limited time maintainers have,the 0.4.0 release of PyVISA-py will be the last version of PyVISA-py supportingPython 2.
