HP 34811A BenchLink Software

The HP 34811A BenchLink Software (HP BenchLink/Arb) package provides a communication link between a personal computer (PC) and the HP 33120A Function/Arbitrary Waveform Generator (function generator). HP BenchLink/Arb allows you to create and edit

waveforms in a Windows environment before transferring them to the

function generator. HP BenchLink/Arb’s key functions are:

• Create and edit arbitrary waveforms up to 16,000 points in length.

• Combine waveforms using mathematical operators including add,

subtract, and multiply.

• Perform other mathematical operations such as clip, absolute, invert,

mirror, smooth, and resize.

• Import X/Y (time/voltage pair) waveforms from Mathcad® and other

BenchLink applications such as HP 34810A BenchLink/Scope.

• Copy waveforms as a bitmap to paste into other applications.

• Transfer waveforms to the HP 33120A function generator.

• Save waveforms to a file for later use.

HP BenchLink/Arb Components

This chapter provides an overview of HP BenchLink/Arb and gives a few exercises to help you get started using the software. This chapter does not describe all the features and functions of HP BenchLink/Arb. Chapter 4 describes the features and functions.

HP BenchLink/Arb Components

waveform edit window

Wave View Window (with zoom locator box)

Status Bar

Title Bar

The Title Bar provides the standard Windows Control-menu box and sizing buttons. In the Title Bar, HP BenchLink/Arb displays the name of any active waveform edit window.

Chapter 2 Quick Start

HP BenchLink/Arb Components

Menu Bar

The Menu Bar contains pull-down menus. Position your cursor over a menu item and click the mouse button to view the menu choices. You can also use the menus by holding the Alt key and typing the underlined letter of the menu choice (for example, Alt+F will display the File menu).

Toolbar

The Toolbar contains icons for quick display of dialog boxes and rapid execution of HP BenchLink/Arb commands. The icons on the Toolbar perform the same tasks as the pull-down menus in the Menu Bar, but do so with a single click.

Palette Bar

The Palette Bar provides quick access to tools used in creating and editing waveforms. Icons allow you to insert new waveform segments into the active waveform window, edit segments already in the waveform window, and to change the view of the waveform by zooming in or out.

Waveform Edit Windows

Waveforms created in HP BenchLink/Arb are displayed in waveform edit windows. Waveforms consist of one or more segments which can be created by inserting standard waveshapes, freehand drawing, line drawing, and performing mathematical operations. Segments can be combined to create virtually any arbitrary waveform you may need.

Wave View Window

The Wave View window allows you to view the entire waveform while you are creating and editing individual segments in the active waveform edit window. Any changes made to the waveform will be reflected in the Wave View window. For convenience, the Wave View window can be placed anywhere on your computer screen.

The Wave View window contains a sampled representation of the waveform, and as such, cannot display every waveform detail. Rather than a precise rendering of the waveform, the Wave View window gives a

general ‘overview’ of the waveform.

Status Bar

The Status Bar provides brief descriptions of the Menu Bar and Toolbar items currently selected and provides specific waveform information depending upon the application mode. It appears at the very bottom of the HP BenchLink/Arb screen and dynamically changes as the various menu commands or modes are selected.

Chapter 2 Quick Start

Starting and Closing HP BenchLink/Arb

Starting. HP BenchLink/Arb can be started in one of three ways:

• From the BenchLink program group, double-click the

BenchLink/Arb icon.

• From the Windows File menu, choose Run... and, assuming

HP BenchLink/Arb was loaded in a directory named ’bench’, enter: \bench\bl_arb.exe.

• From the DOS prompt, assuming HP BenchLink/Arb was loaded in a

directory named ‘bench’, type: win \bench\bl_arb.exe.

Once started, the HP BenchLink/Arb screen can be positioned, sized, maximized, or reduced to an icon using the standard Windows controls in the Title Bar.

The first time you start HP BenchLink/ Arb, the program will prompt you to enter your name and your company name. This information will appear in the banner screen each time you start HP BenchLink/ Arb.

Closing. You can exit from HP BenchLink/Arb in one of two ways:

• From the HP BenchLink/Arb Menu Bar, choose File | Exit.

• Double-click the Windows Control-menu box.

HP BenchLink/Arb will prompt you to save any unsaved waveform windows.

Chapter 2 Quick Start

To Create, Save, and Output an Arbitrary Waveform

This exercise demonstrates how to use HP BenchLink/Arb. An arbitrary waveform is created, edited, saved, and output to the function generator.

1 Start HP BenchLink/Arb as described on the previous page. You should

have an empty waveform edit window displayed.

2 Put a sine wave segment in the waveform edit window by clicking the

Sine Wave icon.

Chapter 2 Quick Start

To Create, Save, and Output an Arbitrary Waveform

3 Add a triangle wave segment to the sine wave by clicking the Triangle

Wave icon. The triangle wave segment is added to the sine wave segment. Notice the tick mark (just above the waveform grids) that shows where the segment begins and ends.

4 Change the triangle wave segment amplitude. Place the cursor anywhere

on the triangle wave segment in the waveform edit window and double-click. The Edit Segment dialog box appears.

Set the amplitude to 0.5. Place the cursor in the AMPLITUDE text box and

type 0.5 or click the up and down arrows next to the Amplitude text box.

Click OK.

Chapter 2 Quick Start

To Create, Save, and Output an Arbitrary Waveform

The triangle wave segment amplitude is reduced to 0.5 and the segment is highlighted.

5 Expand the arbitrary waveform to fill the waveform edit window. Click

on the Math menu choice and then Expand to Fit in the drop-down menu.

The waveform is expanded to fill all 16,000 data points. The waveform fills the entire window and is now considered arbitrary (you cannot edit the sine wave or triangle wave segments independently).
