Command Introduction
Command Syntax
The command system of DS1000CA series digital oscilloscopes presents a
multistate tree structure, each of the subsystem consists of a “Root” keyword and
one or multilayered keywords. Generally, a command line starts with “:” (except
for IEEE commands) and “:” is also used for separating different keywords,
meanwhile, parameters are permitted to follow the keywords; in addition, “?” after
a command line denotes to query its function and “space” is used to divide
command and parameter.
For example:
:TRIGger:EDGE:SLOPe {POSitive|NEGative}
:TRIGger:EDGE:SLOPe?
TRIGger is the root keyword of this command, EDGE and SLOPe are second and
third keyword respectively, all of these keywords are separated by “:”. Connects
enclosed in the “{}” denote the parameters permitted to be set by user; queries
are formed by adding a question mark (?) to the end of the commands and “space”
is used to divide the command :TRIGger:EDGE:SLOPe and the parameter.
