connection
Connect GPIB instruments
quickly and easily to your
computer’s USB port
The Agilent 82357B USB/GPIB
interface provides a direct connection
from the USB port on your desktop
and laptop computers to GPIB instru-
ments. Once the software is loaded,
your computer automatically detects
the 82357B when it is connected to
the USB port of the computer.
The 82357B is a plug-and-play device.
It is also hot-pluggable, making it
easy to connect and disconnect
without having to shut down the
computer. No external power supplies
are necessary.
The 82357B USB/GPIB interface
implements USB 1.1 (12 Mbits/s)
and is compatible with USB 2.0. The
82357B USB/GPIB interface uses a
thin, flexible, high-quality USB cable
that is USB 2.0-compliant. The USB
cable is shielded, and the connector
is specified to 1,500 insertions, ensur-
ing a durable connection and reliable
data transfer.
