Operating Manual 1145.1084.12 – 30 583
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
An optional mnemonic must not be omitted if its effect is additionally specified by a numeric
suffix.
 Long and short form
The key words feature a long form and a short form. Either the short form or the long form can be
entered; other abbreviations are not permitted.
