A.1.2 Syntax for instrument-specific commands
Not all commands used in the following examples are necessarily implemented in the
instrument. For demonstration purposes only, assume the existence of the following
commands for this section:
●
DISPlay[:WINDow<1...4>]:MAXimize <Boolean>
●
FORMat:READings:DATA <type>[,<length>]
●
HCOPy:DEVice:COLor <Boolean>
●
HCOPy:DEVice:CMAP:COLor:RGB <red>,<green>,<blue>
●
HCOPy[:IMMediate]
●
HCOPy:ITEM:ALL
●
HCOPy:ITEM:LABel <string>
●
HCOPy:PAGE:DIMensions:QUADrant[<N>]
●
HCOPy:PAGE:ORIentation LANDscape | PORTrait
●
HCOPy:PAGE:SCALe <numeric value>
●
MMEMory:COPY <file_source>,<file_destination>
●
SENSE:BANDwidth|BWIDth[:RESolution] <numeric_value>
●
SENSe:FREQuency:STOP <numeric value>
●
SENSe:LIST:FREQuency <numeric_value>{,<numeric_value>}
● Long and short form ..............................................................................................805
● Numeric suffixes ....................................................................................................805
● Optional mnemonics ............................................................................................. 806
A.1.2.1 Long and short form
The mnemonics feature a long form and a short form. The short form is marked by
upper case letters, the long form corresponds to the complete word. Either the short
form or the long form can be entered; other abbreviations are not permitted.
Example:
HCOPy:DEVice:COLor ON
is equivalent to
HCOP:DEV:COL ON
.
Case-insensitivity
Upper case and lower case notation only serves to distinguish the two forms in the
manual, the instrument itself is case-insensitive.
A.1.2.2 Numeric suffixes
If a command can be applied to multiple instances of an object, e.g. specific channels
or sources, the required instances can be specified by a suffix added to the command.
Numeric suffixes are indicated by angular brackets (<1...4>, <n>, <i>) and are replaced
