Querying Help for Command Syntax
5-58
The SYSTem[<channel>]:HELP:SYNTax? query causes the
device to return a string containing the syntax specification of the
command associated with the <command_header>, a description of the
command function and any aliases to the command. Each line of the
response is tabbed to the right for readability.
Any <command_header> that is not a valid command header being
recognized by the device, shall cause the device to return a null string
(""). E.g. if the <command_header> contains only a part of the header,
contains an illegal numeric suffix, etc.
The response shall have the following format:
<Description of command>
<command header> <Command parameters
Alias: <list of command that perform the same
function>
Command:
[:]SYSTem[<channel>]:HELP:SYNTax? {<string command>}
Where:
<string command> is the command to look up the syntax
help on.
The following examples demonstrate how to use the syntax help
command.
