AFG1000 Series Arbitrary Function Generator Programmer Manual

Getting Started

Introduction

This programmer guide provides information to use commands for remotely

controlling your instrument. With this information, write computer programs that will

perform functions such as setting the front-panel controls, selecting clock source,

setting sampling rate, and exporting data for use in other programs.

Connecting the Interface

The AFG1000 Series has a USB (type B) connector on the rear panel, as shown

in the following figure. This connector conforms to USB-TMC. Attach a USB

cable to this connector.

Using TekVISA

TekVISA is Tektronix implementation of VISA (Virtual Instrument Software

Architecture), an industry-standard communication protocol. VISA provides

a common standard for software developers so that software from multiple

vendors, such as instrument drivers, can run on the same platform. TekVISA is

industry-compliant software, available with selected Tektronix instruments.

Use this software to write (or draw) interoperable instrument drivers in a

variety of Application Development Environments (ADEs). It implements a

subset of Version 2.2 of the VISA specification for controlling USB

instrument interface locally.
