Figure 6-3: Tree structure the SCPI command systems using the SOURce system as example
Multiple keywords
Some key words occur in several levels within one command system. Their effect
depends on the structure of the command, i.e. at which position in the header of a
command they are inserted.
Example:
SYSTem:COMMunicate:WLAN:[:STATe]
This command contains key word STATe in the fourth command level. It enables or
disables the wireless.
Example:
SYSTem:COMMunicate:WLAN:DHCP[:STATe]
This command contains key word STATe in the fifth command level. It defines the sta-
tus of DHCP.
Optional Keywords
Some command systems permit certain key words to be inserted into the header or
omitted. These key words are marked by square brackets in the description. The full
command length must be recognized by the instrument for reasons of compatibility
with the SCPI standard. Some commands are considerably shortened by these
optional key words.
Example:
[SOURce]:POWer:PROTection[:STATe]
This command activates or deactivates the Overpower Protection (OPP) for the previ-
ous selected channel. The following command has the same effect:
POWer:PROTection
