Remote Programming 9 2 Remote Programming GPIB Capabilities Of The Power Supply All power supply functions except for setting the GPIB address are programmable over the IEEE 488 bus (also known asthe General Purpose Interface Bus or "GPIB"). The IEEE 488.1 capabilities of the power supply ar...
Page 9 - SCPI Messages; Types of SCPI Commands; Structure of a SCPI Message
10 Remote Programming SCPI Messages There are two types of SCPI messages, program and response. • A program message consists of one or more properly formatted SCPI commands sent from the controller to the power supply. The message, which may be sent at any time, requests the power supply to perform ...
