command following the semicolon then starts at the level that is below the
common levels (see also Figure 5–1 on page 5–6). The colon after the
semicolon has to be omitted.
Example:
This command line contains two commands separated by a semicolon. Both
commands belong to the SYSTem system COMMunicate:SERial subsystem;
they have three common levels.
In the shortened command line the second command starts at the level below
SYSTem:COMMunicate:SERial. The colon after the semicolon has to be
omitted.
The shortened form of the command line is:
A new command line always starts with the full path however.
Example:
Unless otherwise expressly specified, a query is defined for each setting
command. The query is generated by appending a question mark to the
associated setting command. The SCPI rules imposed on the query responses are
somewhat stricter than those of the IEEE 488.2 standard:

Example:
Response:
2. Maximum and minimum values can be requested by a special text parameter.
Example:
Response:
3. Numeric values are output without unit. Physical quantities refer to the basic
units.
