Page 13: Multiple Commands In A Message
Introduction to Programming - 2 Types of SCPI Commands SCPI has two types of commands, common and subsystem. ♦ Common commands generally are not related to specfic operation but to controlling overall dc source functions, such as reset, status, and synchronization. All common commands consist of a three-letter nmemonic preceded by an asterisk: *RST *IDN? *SRE 8... -
Page 14: Moving Among Subsystems
2 - Introduction to Programming Moving Among Subsystems In order to combine commands from different subsystems, you need to be able to reset the header path to a null string within a message. You do this by beginning the command with a colon (:), which discards any previous header path. -

Page 16: Scpi Data Formats
2 - Introduction to Programming NOTE: All RS-232 response data sent by the dc source is terminated by the ASCII character pair <carriage return><newline>. This differs from GPIB response data which is terminated by the single character <newline> with EOI asserted. SCPI Data Formats All data programmed to or returned from the dc source is ASCII. -
Page 17: Scpi Command Completion
Introduction to Programming - 2 SCPI Command Completion SCPI commands sent to the dc source are processed either sequentially or in parallel. Sequential commands finish execution before a subsequent command begins. Parallel commands allow other commands to begin executing while the parallel command is still executing. Commands that affect trigger actions are among the parallel commands. -
Page 19: Programming The Dc Source
Programming the DC Source Introduction This chapter contains examples on how to program your dc source. Simple examples show you how to program: u output functions such as voltage and current u internal and external triggers u measurement functions u the status and protection functions NOTE: These examples in this chapter show which commands are used to perform a particular function, but do not show the commands being used in any particular programming... -
Page 20: Output Voltage
3 - Programming the DC Source Output Voltage The output voltage is controlled with the VOLTage command. For example, to set the output voltage to 25 volts, use: VOLTage 125 The dc source can be programmed to turn off its output if the output voltage exceeds a preset peak voltage limit. -
Page 21: Triggering Output Changes
Programming the DC Source - 3 Triggering Output Changes The dc source has two independent trigger systems. One is used for generating output changes, and the other is used for triggering measurements. This section describes the output trigger system. The measurement trigger system is described under "Triggering Measurements".
