Adjustment Instructions
The following instructions guide you through 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. Table 5--4 lists the default card settings.
b. If these settings conflict with your hardware setup, see your GPIB card
manual for alternate settings.

Systems using the combination card (GPIB-PCII/IIA)
can be configured as either a GPIB-PCII or a
GPIB-PCIIA.
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.
NOTE. ALWAYS use this installation procedure when installing this software on a
new computer. This installation program uses parameters you supply (see step 2,
substep c) to create a custom start-up file on your hard disk directory. After
installation, you will be instructed 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 might not
match the computer you copy it to.
1. Create a working disk: Power on and boot your system. Using the proper
DOS commands, copy the adjustment software for your digitizing oscillo-
scope to a working disk.
