Getting Started

The oscillosco

pe has a USB 2.0 High speed 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 u p 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 than 15 devices can be connected to any one line.

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

No 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 device s on the network in a star or linear conﬁguration. Do not

use l

oop or parallel conﬁgurations.

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

def

ault setting for the GPIB c onﬁguration is GPIB Address 1.

To change the GPIB 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-bezel 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.
