Adjustment Instructions
The following instructions describe installing the software on your system,
setting up the oscilloscope for adjustment, and starting the adjustment of the
oscilloscope by the software.
1. Install the proper GPIB card (see System on page 5–2): Use the manual
accompanying your GPIB card to install and configure that card.
2. Configure the GPIB card:
a. This software is compatible with cards configured for PCII and PCIIA
operation. The following table lists the default card settings.
b. If these settings conflict with your hardware setup, see your GPIB card
manual for alternate settings.
c. If you have more than one GPIB card installed, this adjustment software
assumes the first card (referenced 0). See your GPIB card manual for
information on how to determine which card is your “0” card.

Systems using the combination card (GPIB-PCII/IIA)
can be configured as either a GPIB-PCII or a
GPIB-PCIIA.
STOP. ALWAYS use this installation procedure when installing this software on a
new computer. This installation program uses parameters you supply (see step 2,
substep a) to create a custom start-up file on your hard disk directory. After
installation, the software will instruct you to run this start-up batch file
whenever you do software-based adjustments, so it can configure your computer
properly before it runs the adjustment program. Do not simply copy the software
files from one computer to another, since the start-up batch file you copy may not
match the computer you copy it to.
1. Create a working disk: Using the proper DOS commands, copy the
Adjustment Software disk to a working disk.
