Real Number Setting Syntax
Real Number Setting Syntax
This syntax is for setting real values in commands. It is to be used with
commands that require the Real Number Setting Syntax.
An example of a command that requires the Real Number Setting
Syntax is the RFANalyzer:FREQuency command. (See “RFANalyzer
subsystem” on page 303.)
