Reference: Remote Commands ~ Syntax Syntax This section contains information on the Standard commands for Programmable Instruments (SCPI) and IEEE 488.2 Common Commands that may be used to program the OTS9100 10Gb/s SDH/SONET module. IEEE 488.2 Common Commands Description ANSI/IEEE Standard 488.2 defines the codes, formats, protocols, and usage of common commands and queries used on the GPIB interface between the controller and the instruments. The OTS9100 complies with this standard.
Reference: Remote Commands ~ Syntax Block Format IEEE-488 block format is a means of encoding arbitrary binary data, including characters that aren’t valid in text strings, for transmission over a GPIB link. The format is most easily explained with an example.
Reference: Remote Commands ~ Syntax SCPI Commands and Queries SCPI is a standard that provides guidelines for remote programming of instruments. These guidelines provide a consistent programming environment for instrument control and data usage. This environment uses defined programming messages, instrument responses, and data format across all SCPI instruments, regardless of manufacturer. The OTS9100 modules uses a command language derived from this SCPI standard.
Reference: Remote Commands ~ Syntax Parameter types and formats Parameter values may be of several different types, e.g., integer numbers, floating-point numbers, selections from a list of particular values, strings, etc. The following are the parameter types that appear in OTS9100 remote control commands. An integer number. A decimal number with integer and/or fractional parts, e.g., 12.43 A decimal number in scientific notation, e.g., 1.
Reference: Remote Commands ~ Syntax An array of arbitrary binary data (bytes), including characters not in the ASCII printing character set.
Reference: Remote Commands ~ Syntax Abbreviating Commands, Queries, and Parameters You can abbreviate most SCPI commands, queries, and parameters to an accepted short form. This manual shows these short forms as a combination of upper and lower case letters. The upper case letters tell you what the accepted short form should consist of, as shown in Figure 3-2, you can create a short form by using only the upper case letters.
Reference: Remote Commands ~ Syntax Chaining Commands and Queries You can chain several commands or queries together into a single message. To create a chained message, first create a command or query, add a semicolon (;), and then add more commands or queries and semicolons until you are done. Figure 3-3 illustrates a chained message consisting of several commands and queries. The single chained message should end in a command or query, not a semicolon.
Reference: Remote Commands ~ Syntax General Rules Here are some general rules for using SCPI commands, queries, and parameters: You can use single (‘ ’) or double (“ ”) quotation marks for quoted strings, but you cannot use both types of quotation marks for the same string. correct: “This string uses quotation marks correctly.” correct: ‘This string also uses quotation marks correctly.’ incorrect: “This string does not use quotation marks correctly.
