Duplicate Mnemonics
Identical function mnemonics can be used in more than one subsystem.
For example, the function mnemonic RANGe may be used to change the
vertical range or to change the horizontal range:
:CHANnel1:RANGe .4
Sets the vertical range of channel 1 to 0.4 volts full scale.
:TIMebase:RANGe 1
Sets the horizontal time base to 1 second full scale.
:CHANnel1 and :TIMebase are subsystem selectors and determine which
range is being modified.
Tree Traversal Rules and Multiple Commands
Command headers are created by traversing down the Command Tree (see
page 755). A legal command header would be :TIMebase:RANGe. This is
referred to as a compound header. A compound header is a header made
of two or more mnemonics separated by colons. The mnemonic created
contains no spaces.
The following rules apply to traversing the tree:
• A leading colon (<NL> or EOI true on the last byte) places the parser at
the root of the command tree. A leading colon is a colon that is the
first character of a program header. Executing a subsystem command
lets you access that subsystem until a leading colon or a program
message terminator (<NL>) or EOI true is found.
• In the command tree, use the last mnemonic in the compound header
as the reference point (for example, RANGe). Then find the last colon
above that mnemonic (TIMebase:). That is the point where the parser
resides. Any command below that point can be sent within the current
program message without sending the mnemonics which appear above
them (for example, POSition).
