3.5 Programming examples

This section lists examples of programming with SCPI commands based on

NI-VISA or Socket in Visual C ++, Visual Basic, MATLAB, Python, and more.

NI-VISA-based programming examples

1. First confirm that your computer has installed the NI VISA library (NI

website can be downloaded from http://www.ni.com). The default

installation path in this article is C: \Program Files\IVI Foundation\VISA.

2. This article mainly uses the power of the USB interface and PC

communications, some examples involve the use of LAN interface. Please

use the USB cable to connect the USB Device port on the rear panel of the

power supply to the USB port on the PC. You can also use the LAN

interface to communicate with the PC.

3. After the power is correctly connected to the PC for the first time,

power on the instrument. At this time, the

Hardware Update

Wizard dialog

box will pop up. Follow the instructions of the wizard to install the "USB

Test and Measurement Device".

At this point, programming preparation is completed. The following will

detail the Visual C + +, Visual Basic and MATLAB development

environment programming examples.

Visual C ++ programming examples

Environment:

Win7 32bit system, Visual Studio

Example content:

Using NI-VISA, access control devices via
