More About Oscilloscope Commands 11
Agilent InfiniiVision 5000 Series Oscilloscopes Programmer's Guide 663
When a syntax definition specifies that a number is an integer, that means
that the number should be whole. Any fractional part will be ignored,
truncating the number. Numeric data parameters accept fractional values
are called real numbers.
All numbers must be strings of ASCII characters. Thus, when sending the
number 9, you would send a byte representing the ASCII code for the
character 9 (which is 57). A three- digit number like 102 would take up
three bytes (ASCII codes 49, 48, and 50). This is handled automatically
when you include the entire instruction in a string.
Command Tree
The command tree shows all of the commands and the relationships of the
commands to each other. The IEEE 488.2 common commands are not
listed as part of the command tree because they do not affect the position
of the parser within the tree. When a program message terminator (<NL>,
linefeed- ASCII decimal 10) or a leading colon (:) is sent to the instrument,
the parser is set to the root of the command tree.
