Getting Started

GPIB

To use GPIB (Gen

eral Purpose Interface Bus), start by connecting an appropriate

USB cable to the USB 2.0 high-speed (HS) device port on the rear panel of your

oscilloscope. Connect the other end to the TEK-USB-488 Adapter host port. Then

connect a GPIB cable from the TEK-USB-488 Adapter to your PC.

Supply power to the Adapter in either of these two ways:

1. Use the optional 5 V

power adapter connected to the 5 V

power input

on the Adapter.

2. Use an appropriate USB cable connected to a powered USB host port on your

PC and the Device port on the TEK-USB-488 Adapter.

The oscilloscope has a USB 2.0 high-speed (HS) device port to control the

oscilloscope through USBTMC or GPIB with a TEK-USB-488 Adapter. The

USBTMC protocol allows USB devices to communicate using IEEE488 style

messages. This lets you run your GPIB software applications on USB hardware.

Before setting up the oscilloscope for remote communication using the electronic

(physical) GPIB interface, you should familiarize yourself with the following

GPIB requirements:

A unique device address must be assigned to each device on the bus. No two

devices can share the same device address.

No more than 15 devices can be connected to any one line.

One device should be connected for every 6 feet (2 meters) of cable used.

No more than 65 feet (20 meters) of cable should be used to connect devices

to a bus.

At least two-thirds of the devices on the network should be powered on while

using the network.

Connect the devices on the network in a star or linear conﬁguration. Do not

use loop or parallel conﬁgurations.

To function correctly, your oscilloscope must have a unique device address. The

default setting for the GPIB conﬁguration is GPIB Address 1.

Getting Started

To change the GP

IB address settings, do the following:

1. On the front panel, push Utility.

2. Push Utility Page.

3. Select I/O with the Multipurpose knob.

4. Push GPIB.

5. Enter the GPIB address on the side menu, using the multipurpose knob. This

will set the GPIB address on an attached TEK-USB-488 Adapter.

The oscilloscope is now set up for bidirectional communication with your

controller.

Setting Up Remote Communications Software

Connect your oscilloscope directly to a computer to let the PC analyze your data,

collect screen images, or to control the oscilloscope using a program of your own

creation. Three ways to connect your oscilloscope to a computer are throughthe

VISA drivers, the e*Scope Web-enabled tools, or via a socket server.

Using

VISA

VISA lets you use your MS-Windows computer to acquire data from your

oscilloscope for use in an analysis package that runs on your PC, such as

Microsoft Excel, National Instruments LabVIEW, Tektronix OpenChoice Desktop

soft

ware, or your own custom software. You can use a common communications

connection, such as USB, Ethernet, or GPIB, to connect the computer to the

oscilloscope.

To set up VISA communications between your oscilloscope and a computer:

MDO4000/B/C, MSO/DPO4000B and MDO3000 Series Oscilloscopes Programmer Manual 1-11

Getting Started

1. Load the VISA dr

ivers on your computer. Also, load your application, such

as OpenChoice Desktop. You will ﬁnd the drivers and OpenChoice Desktop

software on the appropriate CD that comes with your oscilloscope or at the

Tektronix software ﬁnder Web page (www.tektronix.com\downloads).

2. Connect the oscilloscope to your computer with the appropriate USB or

Ethernet cable. To communicate between the oscilloscope and a GPIB system,

connect the oscilloscope to the TEK-USB-488 GPIB-to-USB Adapter with

a USB cable. Then connect the adapter to your GPIB system with a GPIB

cable. Cyc

le the power on the oscilloscope.

3. Push Utility.

4. Push Utility Page.

5. Turn multipurpose knob a and select I/O.

6. If you are using USB, the system sets itself up automatically for you, if USB is

enabled. Check USB on the lower menu to be sure that USB is enabled. If it is

not enabled, push USB. Then push Connect to Computer on the side menu.

7. To use Ethernet, push Ethernet & LXI on the lower menu. Use the side menu

buttons to adjust your network settings, as needed. For more information, see

the e*Scope setup information below.

8. If you want to change socket server parameters, push Socket Server and enter

new values through the resulting side menu.

9. If you are using GPIB, push GPIB. Enter the GPIB address on the side menu,

using multipurpose knob a. This will set the GPIB address on an attached

TEK

-USB-488 Adapter.

10. Run your application software on your computer.

ick Tips

Your oscilloscope shipped with a CD containing a variety of Windows-based

software tools for efﬁcient connectivity between your oscilloscope and your

computer. These include toolbars that speed connectivity with Microsoft

xcel and Word. There are also two standalone acquisition programs called

NI LabVIEW SignalExpress™, Tektronix Edition and Tektronix OpenChoice

Desktop.

The rear-panel USB 2.0 high-speed (HS) device port is the correct USB port

for computer connectivity. Use the rear- and front-panel USB 2.0 host ports

to connect your oscilloscope to USB ﬂash drives, hard drives, printers and

keyboards. Use the USB Device port to connect your oscilloscope to a PC or

a PictBridge printer.
