Data Types

The analyzer uses a number of different data types during data
transfers. Data transfer occurs in response to a query. The data type
used is determined by the parameter being queried. Data types described
in this section are:

• Numeric Data

• Character Data

• String Data
• Expression Data
• Block Data
Numeric Data
The analyzer returns three types of numeric data in response to queries:
NR1 data Integers (such as +1, 0, -1, 123, -12345). This is the
response type for boolean parameters as well as some
numeric parameters.
NR2 data Floating point numbers with an explicit decimal point
(such as 12.3, +1.234, -0.12345).
NR3 data Floating point numbers in scientific notation (such as
+1.23E+5, +123.4E-3, -456.789E+6).
Character Data
Character data consists of ASCII characters grouped together in
mnemonics that represent specific instrument settings (such as
MAXimum, MINimum or MLOGarithmic). The analyzer always returns the
short form of the mnemonic in upper-case alpha characters.
