and lower-case.
(The three types of headers, FREQUENCY, Frequency, and frequency are all interpretable as the same header.)
Example: Long form → :FREQuency:SWEep:MODE AUTO
Short form → :FREQ:SWE:MODE AUTO
Long + Short → :FREQ:SWEep:MODE AUTO
<Option node>
The symbol [ ] indicates an option node. The header enclosed within the [ ] may abbreviated. It is accepted as a
command whether abridged or unabridged.
Example: When a header is abridged → :FREQuency:CW 10 MHz
When a header is unabridged → :FREQuency 10 MHz
<Command separator>
One or more spaces must be placed between a command and a parameter. Two or more parameters must be
separated with a comma ( , ).
6.2.5 Compounding Commands
Commands can be chained with a semicolon ( ; ) as shown in the following examples. The second command is
referred to the same level as the lowest layer of the first command. This allows the second command to be written
with the full path name, as shown in the example 1. However, as shown in example 2, the header with a higher order
than SWEep can be omitted.
Example: 1 → :FREQuency:SWEep:MODE AUTO;:FREQuency:SWEep:TIME 50 ms
2 → :FREQuency:SWEep:MODE AUTO;TIME 50 ms
