OA 5000 Series User Manual 3 --- 1

Setting Up the Instrument

This section tellsyou how to prepare the OA 5000 Optical Attenuator for use

with a remote controlleror computer. The first part of this section explains

how to connect the OA 5000 toa controller or computer through the GPIB

interface. The rest of the section describeshow to use the OA 5000 front

panel settings to enablethe OA 5000 to send and receive messages to and

from a remote controller.

NOTE

In addition to the information in this manual, you will need to con-

sult the documentation for your controller to determine how to send

commands, send interface messages such as local lockout and

serial poll, andreceive query responses from within theprogram-

ming language running on your controller or computer.Also, you

will needto determine how to assert variousGPIB lines, including

remoteenable and attention from within theprogramming lan-

guage running your controller or computer.

Youcan control the OA 5000 with a remote controller or computer that uses

the IEEE Std 488.1-1987 (GPIB) interface.

The OA 5000 is connected tothe GPIB through the TM5000 Series power

module in which itis installed. Connect the TM5000 power module to the

GPIB using an IEEE Std 488 GPIB cable(available as Tektronix part number

012-0991-00). The TM5000 power module has a 24-pin GPIBconnector on

its rear panel (Figure3 -1). Thisconnector has a D -typeshell and conforms

to IEEE Std 488.

Youcan also stack GPIB connectors.
