Command Syntax
Argument Types
Commands use arguments such as enumeration, numeric, quoted string and block.
Each of these arguments are listed in detail below.
Enumeration
Enter these arguments as unquoted text words. Like key words, enumeration
arguments follow the same convention where the portion indicated in uppercase is
required and that in lowercase is optional.
For example:
SAVe:WAVEform:FILEFormat INTERNal
Numeric
Many oscilloscope commands require numeric arguments. The syntax shows
the format that the oscilloscope returns in response to a query. This is also the
preferred format when sending the command to the oscilloscope though any of
the formats will be accepted. This documentation represents these arguments as
described below.
Table 2-10: Numeric Arguments
Symbol Meaning
<NR1> Signed integer value
<NR2> Floating point value without an exponent
<NR3> Floating point value with an exponent
<bin> Digital data in binary format
Most numeric arguments will be automatically forced to a valid setting, by either
rounding or truncating,, when an invalid number is input, unless otherwise noted
in the command description.
Quoted String Some commands accept or return data in the form of a quoted string, which is
simply a group of ASCII characters enclosed by a single quote (’) or double quote
("). The following is an example of a quoted string:
"This is a quoted
string"
. This documentation represents these arguments as follows:
