HP E1433A User's Guide

Installing the HP E1433A

To install the HP E1433A

Caution To protect circuits from static discharge, observe anti-static techniques

whenever handling the HP E1433A 8-Channel 196 kSa/s Digitizer plus DSP Module.

1 Set up your VXI mainframe. See the installation guide for your mainframe.

2 Select a slot in the VXI mainframe for the HP E1433A module.

The HP E1433A module’s local bus receives ECL-level data from the module immediately to its left and outputs ECL-level data to the module immediately to its right. Every module using the local bus is keyed to prevent two modules from fitting next to each other unless they are compatible. If you will be using the local bus, select adjacent slots immediately to the left of the data-receiving module. The local bus can support up to four HP E1433A modules at full span at real time data rates. If the VXI Bus is used, maximum data rates will be reduced but the module can be placed in any available slot.

3 Using a small screwdriver or similar tool, set the logical address configuration

switch on the HP E1433A.

(See the illustration on the next page.) Each module in the system must have a unique logical address. The factory default setting is 0000 1000 (8). If an HP-IB command module will be controlling the HP E1433A module, select an address that is a multiple of 8. If your VXI system dynamically configures logical addresses, set the switch to 255.

HP E1433A User's Guide

Installing the HP E1433A

To transport the module

• Package the module using the original factory packaging or packaging identical

to the factory packaging.

Containers and materials identical to those used in factory packaging are available through Hewlett-Packard offices.

• If returning the module to Hewlett-Packard for service, attach a tag describing

the following:

q Type of service required q Return address q Model number q Full serial number

In any correspondence, refer to the module by model number and full serial number.

• Mark the container FRAGILE to ensure careful handling.

• If necessary to package the module in a container other than original

packaging, observe the following (use of other packaging is not recommended):

q Wrap the module in heavy paper or anti-static plastic. q Protect the front panel with cardboard. q Use a double-wall carton made of at least 350-pound test material. q Cushion the module to prevent damage.

Caution Do not use styrene pellets in any shape as packing material for the module. The

pellets do not adequately cushion the module and do not prevent the module from shifting in the carton. In addition, the pellets create static electricity which can damage electronic components.

Introduction

This chapter will help you to get your HP E1433A running and making simple measurements. It shows how to install the software libraries and how to run some of the example programs that are included.

For more information see the other chapters in this book and the on-line function reference. (See “Where to get more information” in the chapter titled “Using the HP E1433A).”

Two versions of the Host Interface Library are available. One is the HP-UX C-Language Host Interface Library which uses SICL (the Standard Instrument Interface Library) to communicate to the HP E1433A hardware. The other is the HP-UX, Windows 95 and Windows NT VXIplug&play Library which communicates with the hardware using VISA (Virtual Instrument Software Architecture). VISA is the input/output standard upon which all the VXIplug&play software components are based.

This chapter mainly covers the VXIplug&play version, and it also includes some examples using the C-Language version. If you are using the C-Language version, you should also refer to the chapter titled “The C-Language Host Interface Library.”

The Resource Manager

The Resource Manager is a program from your hardware interface manufacturer. It looks at the VXI mainframe to determine what modules are installed. You need to run it every time you power up. If you get the message: “No HP E1433A can be found in this system,” then run the Resource Manager.

Before running the HP E1432A /HP E1433A software make sure that your hardware is configured correctly and that the Resource Manager runs successfully. Before using your measurement system, you must set up all of its devices, including setting their addresses and local bus locations. No two devices can have the same address. Usually addresses 0 and 1 are taken by the Resource Manager and are not available.

For more information about the Resource Manager, see the documentation with your hardware interface.
