The uppercase letters of a mnemonic represent the short form of the mnemonic, whereas the long form of a mnemonic is the short form followed by the lowercase letters. The test set accepts either the long form or the short form of the mnemonic.
Complex commands are valuable because they set the state of the parameter and a value for that parameter. For example, a command that contains the mnemonic [:SAMPlitude] is a complex command that sets the state to ON as well as the amplitude. You can use parameters such as amplitude, frequency, gain, number, time, and value as a complex command. Refer to the specific command for the parameter that applies.
Some commands have optional units of measurement. These are displayed in square brackets. If no units are specified in the command then the default unit in
below is used. The test set accepts the specified unit either with or without a space inserted between the <num value> and the unit (for example, both
are valid). The following table summarizes the units available.
The [:SELected] Mnemonic is an optional mnemonic that implies a current selection on the test set. Often there are other mnemonics that can be used in place of the [:SELected] mnemonic to configure a setting that is not the currently selected configuration on the test set. The mnemonics that can replace the [:SELected] mnemonic are listed in parentheses separated by vertical bars ( | ) in the description table title. An example of a command that contains the [:SELected] mnemonic is shown in the following table.
When the setting and query values of a GPIB command are strings, a single quote is needed around the strings when setting the command, while the test set returns the result in double quoted strings when querying.
OUTPUT 714;"SYSTem:APPLication:FORMat '1xEV-DO'"
OUTPUT 714;"SYSTem:APPLication:FORMat?" !The test set returns "1xEV-DO". Note here the strings are enclosed in double quote.
