Page 104 GPP-3610H/GPP-7250 User Manual Command Syntax The commands that are used with the GPP meet IEEE488.2 and SCPI standards. SCPI Commands Overview Command Format SCPI is an ASCII based command language designed for test and measurement instruments. SCPI commands uses a hierarchical structure (tree system), and is divided into different subsystems.
Page 105 REMOTE CONTROL Symbol Description SCPI commands have the following conventional symbols. These symbols are not commands but are used to describe the command parameters. 1. Curly Brackets { } Curly Bracket enclose command string parameters, for example: {OFF|ON} 2. Vertical Bars | Vertical bars are used to separate one or more optional parameters.
Page 106 GPP-3610H/GPP-7250 User Manual Parameter Types The commands have a number of different parameter categories. How the parameters are set depend on the parameter categories. 1. Boolean Commands parameter that have to states “OFF” and “ON”, for example, DISPlay:FOCUs {ON|OFF}. “ON” will turn on the focus display function, while “OFF”...
Page 107 REMOTE CONTROL 5. ASCII Strings ASCII string parameters must use a combination of ASCII characters in a string. For example: For the command: MODE <name>, <name> must be an ASCII string. Command Abbreviations The syntax for SCPI commands contains a combination of upper and lower case letters.

Page 184 GPP-3610H/GPP-7250 User Manual Event Registers The operation, measurement and questionable status register groups all have event registers. The event registers are read only registers that reflect the status of the unit. Individual bits in the event registers are latched (set) when a corresponding event occurs and will remain latched even if the corresponding event changes, as long as the event bit is still set.
