Getting Started
This chapter describes the use of the MB100 Multi-Channel BER Tester
Remote Interfaces . Since the remote interfaces enable automatic testing, the user
does not have to complete any of the manual procedures necessary for front
panel operation . However, the user can write programs to conduct the test
sessions .
Using the GPIB Interface
The MB100 supports remote control through the GPIB interface bus connector
on the rear panel . The unit can be operated from the front panel and over the
remote interface simultaneously . Any unit changes made remotely are displayed
on the front panel . All of the front panel functions can be controlled over the
GPIB interface, except ` POWER.'
Remote commands sent to the MB100 differ from front panel control . The
current operating mode is entered directly rather than through submenus.
GPIB Interface Device Settings
For proper GPIB Interface communication and handshaking, the GPIB controller
(system that controls the operation) and the device (MB100 ) must have their
addresses and terminating characters set up before use . To change these GPIB
parameters, refer to the section in this manual on "Utility" .
Each instrument on the GPIB interface bus needs a unique INSTRUMENT
address . The INSTRUMENT address range for the MB100 is
- 30 decimals .
The GPIB Message Terminator is et to either EOI or EOL/LF . For EOI, the EOI
line will be asserted when the last byte of a message is transmitted . For EOI/LF ,
the last byte of the message will be the line feed character, and the EOI line will
be asserted with its transmission .
