Remote Programing 11. REMOTE PROGRAMMING 11.1. Introduction Programming convention Tree concept Example The SCPI commands have a branching structure. A command must end with a terminator, or <;>. If commands are separated by the character <;> and are located in the same directory, there is no need to repeat the whole tree. Otherwise, use the <:> character followed by the full name of the command.
Remote Programing Format of the parameters The parameters can be key words, digital values, character strings, or digital expressions. The interpreter is case-insensitive. Key words The key words can take two forms, like the instructions: the abbreviated form (in upper-case) The complete form (abbreviated form plus lower-case complement). Thus, for some commands, we will find the parameters: ON, OFF corresponding to the Boolean values (1,0) EDGE, PULse, DELay, EVENt or TV for the triggering modes.
Remote Programing Special values MAXimum, MINimum are used to obtain the extreme values of the parameter. UP, DOWN are used to go to the value following or preceding the current state of the parameter. Character strings These are series of letters and/or digits enclosed in quotation marks " ". Terminator We use as the general term designating a terminator. NL is the CR character (ASCII code 13 or 0x0D). A command line must not be more than 80 characters long; it is terminated by a terminator.
