Command Format Used in This Manual
The format used to show commands in this manual is illustrated below:
FREQuency {<frequency>|MINimum|MAXimum}
The command syntax shows most commands (and some parameters) as
a mixture of upper- and lower-case letters. The upper-case letters
indicate the abbreviated spelling for the command. For shorter program
lines, you can send the abbreviated form. For better program readability,
you can send the long form.
For example, in the above syntax statement, FREQ and FREQUENCY are
both acceptable forms. You can use upper- or lower-case letters.
Therefore, FREQUENCY, freq, and Freq are all acceptable. Other forms,
such as FRE and FREQUEN, will generate an error.
• Braces ( { } ) enclose the parameter choices for a given command string.
The braces are not sent with the command string.
• A vertical bar ( | ) separates multiple parameter choices for a given
command string.
• Triangle brackets ( < > ) indicate that you must specify a value for the
enclosed parameter. For example, the above syntax statement shows
the frequency parameter enclosed in triangle brackets. The brackets
are not sent with the command string. You must specify a value for
the parameter (such as "FREQ 5000").
• Some parameters are enclosed in square brackets ( [ ] ). The square
brackets indicate that the parameter is optional and can be omitted.
The brackets are not sent with the command string. If you do not
specify a value for an optional parameter, the function generator
chooses a default value.
