intelligent instruments can be collected, as well as an auto test system can be composed
conveniently with other test instrument. In the same bus, many test instruments can be connected
simultaneously. In this instrument, the IEEE488.2standard is adopted, and the interface board can
be selected and bought by user. The control instruction system is open, so user can use the
computer operation interface, also can write a program based on this system to achieve the goal.
The control instruction system supports most function that is to say; all function can be operated on
controlling the computer to realize the remote control.

When using GPIB system, the points below should be paid attention to:
z
The total length of cable in one bus system must be less than or equal to two meters times the
number of devices connected on the bus (the GPIB controller counts as one device) and the total
length of cable must not exceed 20 meters.
z
A maximum of 15 devices can be connected in one bus system.
z
There are no restrictions on how the cables are connected together. However, it is
recommended that no more than four piggyback connectors be stacked together on any one device.
