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 instruments. 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, fl exible,
high-quality USB cable that is USB 2.0-
compliant. The USB cable is shielded,
and the connector is specifi ed to 1,500
insertions, ensuring a durable connection
and reliable data transfer.
