Example:
SENSe
This mnemonic identifies the command system
SENSe
.
For commands of lower levels, the complete path has to be specified, starting on the left
with the highest level, the individual key words being separated by a colon ":".
Example:
SENSe:FREQuency:STARt 1GHZ
This command is located on the third level of the
SENSe
system. It defines the start
frequency of the sweep.
The following rules simplify and abbreviate the command syntax:
Multiple mnemonics
Some mnemonics occur on several levels within one command system. Their effect depends on
the structure of the command, i. e. on the position in the command header they are inserted in.
Example:
SOURce:FREQuency:CW lGHZ
This command contains the key word
SOURce
in the first command level. It defines the frequency
for sweep types operating at fixed frequency.
TRIGger:SOURce EXTernal
This command contains the key word
SOURce
in the second command level. It defines the trigger
source “external trigger”.
Optional mnemonics
Some command systems permit certain mnemonics to be optionally inserted into the header or
omitted. These mnemonics are marked by square brackets in this manual. The full command
length must be recognized by the instrument for reasons of compatibility with the SCPI standard.
Some commands are considerably shortened by omitting optional mnemonics.
Example:
TRIGger[:SEQuence]:SOURce EXTernal
This command defines the trigger source “external trigger”. The following command has the same
effect:
TRIGger:SOURce EXTernal
