Introduction

Management of devices on MS Windows controllers are

very different than on UNIX controllers.

On MS Windows controllers, most devices are managed

invisibly by the operating system. A small number of

devices (primarily GPIB) are mirrored in the

$AGILENT3070_ROOT/dev directory so that the 3070

software will execute properly.

Location of Device Files

Device files can be found in the directory:

$AGILENT3070_ROOT/dev

and are listed in Table 8-14.

If a DUT Power Supply is Replaced

Change the appropriate ps<x> file if the GPIB address

of any power supply changes.

Example 2 shows the contents of the default ps0 file. In

the line:

7,22

represents the GPIB address.

Example 8-2 Contents of the default ps0 file
