5. Programming Conventions
Many of the commands allow the entry of optional command parameters. This allows faster remote control as
well as simplified parameter setting. Response parameters may also be optionally specified. This is useful when
only particular components of a complex measurement are important in the application.
Optional
Command Parameters
The majority of the commands have parameters which may be optionally given in a <Command Message>. Each
command's manual entry specifies which parameters are optional. Parameters that are not entered by the user, are
not modified. In cases where other parameter settings are dependent upon an optional parameter which is not
specified, the dependent parameter uses the current value of the parameter.
The syntactic format for a command with optional cProgram Data> parameters is:
Where Header is either a <Command Pro,- Header> or a <Query Program Header> and P,
is a cProgram Data>.
The cProgram Data Separator, the comma, is used as a place mark to indicate unspecified parameters. Trailing
commas may be left off the command.
The following examples show both correct and incorrect usage of the optional command parameters. The
command RG is used to modify the RF-Control to generate mode. The command takes 5 parameters:
Generate Frequency
Generate Port
Output Level
Modulation Type
Bandwidth
The parameter P3, Output Level, is dependent upon the value of the parameter P2, Generate Port_ These two
