SCPI command syntax
Tree structure
SCPI commands are organized in a tree structure, similar to disk directories in computer op-
erating systems. Each subdirectory is called a subsystem. For example, part of the
SENSe1 sub-
system is listed below and shown in Figure 16.
[SENSe[1]]
:DATA?
:FUNCtion "<name>"
:VOLTage
:DC
:RANGE
[:UPPer] <n>
:AUTO <Boolean> | ONCE
:REFerence <n>
:STATe <Boolean>
:ACQuire
