 Query 
A query is a simple or 
compound command 
followed by a question mark 
(?). A parameter (data) is 
returned. 
 Example 
meas:curr:dc? 
 Compound 
Two or more commands on 
the same command line. 
Compound commands are 
separated with either a semi-
colon (;) or a semi-colon and a 
colon (;:). 
A semi-colon is used to join 
two related commands, with 
the caveat that the last 
command must begin at the 
last node of the first 
command.  
A semi-colon and colon are 
used to combine two 
commands from different 
nodes.  
 Example 
meas:volt:dc?;:meas:curr:dc?
