Manual Version 1.2

Digital Oscilloscope Series

Version Declaration

This chapter indicates the modifications of commands in the most recent

release of the programming guide version.

Introduction

Manual version 1.2 describes all the currently available commands. Some

of the commands vary between the oscilloscope series, and these will be

annotated in the description of command.

The following are the main revisions:

wDelete the Table of Commands & Queries, and all the instructions are

classified according to the functional modules.

wRemoved incorrect instructions, added instructions for GEN and DIGITAL

modules.

wAdd two new communication features: Telnet and Socket, visible in

“Programming Overview-Remote Control”.

wDetailed programming instances for instructions (WF?/SCDP) to make

it easier to understand.

wSupport obtaining waveform data of Digital channel and Math.

Digital Oscilloscope Series

Programming Overview

This chapter introduces how to build communication between the instrument and

the PC. It also introduces how to configure a system for remote instrument control.

By using USB and LAN interfaces, in combination with NI-VISA and

programming languages, users can remotely control the instruments. Through LAN

interface, VXI-11, Sockets and Telnet protocols can be used to communicate with

the instruments.

Establishing Communications

Install NI-VISA

Before programming, you need to install the National Instruments NI-VISA

library, which you can download from the National Instruments web site.

Currently, NI-VISA is packaged in two versions: a full version and a Run-Time

Engine version. The full version includes the NI device drivers and a tool named

NI MAX which is a user interface to control and test remotely connected

devices. The Run-Time Engine is recommended, as it is a much smaller

download than the full version and includes the necessary tools for basic

communication to instruments.

For example, you can get the NI-VISA 5.4 full version from:

http://www.ni.com/download/ni-visa-5.4/4230/en/.

You also can download NI-VISA Run-Time Engine 5.4 to your PC and install it

as the default selection. Its installation process is similar with the full version.

After you downloaded the file, follow these steps to install NI-VISA (The full

version of NI-VISA 5.4 is used in this example. Newer versions are likely, and

should be compatible with Teledyne Test Tools instrumentation. Download the

latest version available for the operating system being used by the controlling

computer):

a. Double click the visa540_full.exe, dialog shown as below:

Digital Oscilloscope Series

b. Click Unzip, the installation process will automatically launch after unzipping

files. If your computer needs to install .NET Framework 4, it may auto start.

c. The NI-VISA installing dialog is shown above. Click Next to start the

installation process.

Digital Oscilloscope Series

d. Set the install path, default path is “C:\Program Files\National Instruments\”,

you can change it. Click Next, dialog shown as above.

e. Click Next twice, in the License Agreement dialog, select the “I accept the

above 2 License Agreement(s).”,and click Next, dialog shown as below:

Digital Oscilloscope Series

f. Click Next to begin installation.

g. Now the installation is complete. Reboot your PC.

Digital Oscilloscope Series

Connect the Instrument

Depending on the specific model, your oscilloscope may be able to communicate

with a PC through the USB or LAN interface.

Connect the instrument and the USB Host interface of the PC using a USB cable.

Assuming your PC is already turned on, turn on your oscilloscope, and then the

PC will display the “Device Setup” screen as it automatically installs the device

driver as shown below.

Wait for the installation to complete and then proceed to the next step.
