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 osci

lloscope 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 o scilloscope though any of

the formats will be accepted. This documentation rep resents 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

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 s tring:

"This i s a quote d

string"

. This documentation represents these arguments as follows:
