Safety Summary Ground the Instrument To minimize shock hazard, the instrument chassis and cover must be connected to an electrical protective earth ground. The instrument must be connected to the ac power mains through a grounded power cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that coul

General Programming Aspects The GP-IB Interface Bus The GP-IB Interface Bus The General Purpose Interface Bus is the interface used for communication between a controller and an external device, such as the Agilent 81130A. The GPIB conforms to IEEE standard 488-1987, ANSI standard MC 1.1, and IEC recommendation 625-1. If you are not familiar with the GPIB, please refer to the following books: • The Institute of Electrical and Electronic Engineers: IEEE Standard 488.1-1987, IEEE Standard Dig

General Programming Aspects Programming Recommendations Programming Recommendations Here are some recommendations for programming the instrument: • Start programming from the default setting. The common command for setting the default setting is: *RST • Switch off the automatic update of the display to increase the programming speed. The device command for switching off the display is: :DISPlay OFF • The SCPI standard defines a long and a short form of the commands. For fast programming

General Programming Aspects Programming Recommendations When you have found the correct setting, then use this to create the program. In the program it is recommended to send the command for enabling outputs (for example, :OUTPut ON) as the last command. With this procedure it is possible to switch off the error check system (:SYSTem:CHECk OFF) to increase programming speed. The error check is enabled again by sending *RST. *RST # set default settings :DISP OFF # switch off display update
