Overview of syntax elements
The following tables provide an overview of the syntax elements and special characters.
: | The colon separates the mnemonics of a command. |
; | The semicolon separates two commands of a command line. It does not change the path. |
, | The comma separates several parameters of a command. |
? | The question mark defines a query. |
* | The asterisk defines a common command. |
' " | Quotation marks introduce a string and terminate it. Both single and double quotation marks are possible. |
# | The hash symbol introduces the following numeric formats:
|
A "white space" (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates the header from the parameters. |
| | Parameters A pipe in parameter definitions indicates alternative possibilities in the sense of "or". The effect of the command differs depending on which parameter is used. Example: Definition:HCOPy:PAGE:ORIentation LANDscape | PORTrait Command HCOP:PAGE:ORI LAND specifies landscape orientation Command HCOP:PAGE:ORI PORT specifies portrait orientation Mnemonics A selection of mnemonics with an identical effect exists for several commands. These mnemonics are indicated in the same line; they are separated by a pipe. Only one of these mnemonics needs to be included in the header of the command. The effect of the command is independent of which of the mnemonics is used. Example: Definition SENSE:BANDwidth|BWIDth[:RESolution] <numeric_value> The two following commands with identical meaning can be created: SENS:BAND:RES 1 SENS:BWID:RES 1 |
[ ] | Mnemonics in square brackets are optional and can be inserted into the header or omitted. Example: HCOPy[:IMMediate] HCOP:IMM is equivalent to HCOP |
{ } | Parameters in curly brackets are optional and can be inserted once or several times, or omitted. Example: SENSe:LIST:FREQuency <numeric_value>{,<numeric_value>} The following are valid commands: SENS:LIST:FREQ 10 SENS:LIST:FREQ 10,20 SENS:LIST:FREQ 10,20,30,40 |
