R&S NGL-B105 (P/N: 3652.6356.02) or R&S NGM-B105 (P/N: 3641.6220.02) option
needs to be installed for the remote command of R&S
NGL/NGM via GPIB interface.
The GPIB interface, sometimes called the General Purpose Interface Bus (GPIB), is a
general purpose digital interface system that can be used to transfer data between two
or more devices. Some of its key features are:
●
Up to 15 instruments can be connected
●
The total cable length is restricted to a maximum of 15 m; the cable length between
two instruments should not exceed 2m
●
A wired "OR"-connection is used if several instruments are connected in parallel
To be able to control the instrument via the GPIB bus, the instrument and the controller
must be linked by a GPIB bus cable. A GPIB bus card, the card drivers and the pro-
gram libraries for the programming language must be provided in the controller. The
controller must address the instrument with the GPIB instrument address.
