Table 3-5
Command and Query Parameter Types
Type
Explanations and Examples
<numeric value>
<Boolean>
<literal>
<NRf>
<string>
<non-decimal
numeric>
Accepts all commonly used decimal representation of numbers including optional signs, decimal points, and
scientific notation:
123, 123e2, –123, –1.23e2, .123, 1.23e–2, 1.23000E–01.
Special cases include MINimum and MAXimum as follows: MINimum selects minimum value available, and
MAXimum selects maximum value available.
Queries using MINimum or MAXimum return the associated numeric value.
Represents a single binary condition that is either true or false:
1 or ON, 0 or OFF (Query response returns only 1 or 0.)
An <NRf> is rounded to an integer. A non-zero value is interpreted as 1.
Selects from a finite number of choices. These parameters use mnemonics to represent each valid setting.
An example is the INPut:COUPling AC | DC command parameters (AC | DC).
Flexible numeric representation.
A string parameter is delimited by either single quotes or double quotes. Within the quotes, any characters
in the ASCII 7-bit code may be specified.
The following BASIC statement sends a command containing a <string> parameter:
OUTPUT 703;"FUNC ‘FREQ’"
Format for specifying hexadecimal (#H1F), octal (#Q1077), and binary (#B10101011) numbers using ASCII
characters. May be used in :STATus subsystem commands.
