Connect GPIB instruments quickly and
easily to your computer’s USB port
The Agilent 82357B USB/GPIB
interface provides a direct connec-
tion from the USB port on your
desktop and laptop computers to
GPIB instruments. Once the soft-
ware is loaded, your computer
automatically detects the 82357B
when it is connected to the com-
puter USB port.
With the 82357B USB/GPIB inter-
face and its convenient plug-and-
play feature, you just plug and go.
It is also hot pluggable, making it
easy to connect and disconnect
without having to shut down the
computer. No external power sup-
plies are necessary.
The 82357B USB/GPIB interface
implements USB 2.0 (480 Mbits/s)
and is backward compatible with
USB 1.1. The 82357B USB/GPIB
interface uses a thin, flexible, high-
quality USB cable that is USB 2.0
compliant. The USB cable is shield-
ed, and the connector is specified
to 1,500 insertions, ensuring a
durable connection and reliable
data transfer.
