1 Installing and Configuring the 82350B
10 82350B Installation and Configuration Guide
Connecting instruments to the 82350B
After the 82350B is installed in your PC, the next step is to
connect your GPIB instruments to the installed 82350B.
Suggested steps follow. When you have made the
connections, go to
“Step 4: Configuring the 82350B“ .
1 Review Connection Guidelines. The recommended method
for connecting a GPIB system is a linear arrangement with
the system controller (PC) at one end of the system.
However, a GPIB system can also be connected together in
a star, linear, or a combination configuration as long as the
total number of devices on the system is
≤
14 and these
guidelines are followed:
• To minimize stress on connector mountings, no more
than three cable connectors blocks should be stacked on
top of one another. The GPIB connector screws should
be finger-tightened only.
• Minimize cable length as much as possible. All system
devices must have tri-state drivers and must be powered
on. Systems with devices not using tri-state drivers are
limited to transfer rates < 250 Kbytes/sec.
• For operation with data transfer rates <500 Kbytes/sec,
the total length of all GPIB cables is
≤2 meters times the
number of devices connected together, up to a maximum
of 20 meters.
• For operation with data transfer rates > 500 Kbytes/sec,
the total length of all GPIB cables is > 1 meter times the
number of devices connected together, up to a maximum
of 15 meters.
• The length between adjacent devices is not critical as
long as the overall restriction is met. GPIB bus extenders
are available that allow operation over much greater
distances.
2 Connect GPIB Cables to the 82350B. Connect a separate
GPIB cable to each installed 82350B. Tighten the GPIB
connector screws finger-tight only. (The screwdriver slots
are for removal purposes only.) Two examples follow
showing how to connect a single GPIB instrument or how to
connect multiple GPIB instruments.
