Data Types

FTB-2 and FTB-2 Pro 319

Applicable Data Types for Input—IEEE 488.2

 <CHARACTER PROGRAM DATA>

This data type will be used to send short mnemonics when a

<DECIMAL NUMERIC PROGRAM DATA> cannot be used.

Examples: TRIANGLEWAVE, NCONTINUOUS

 <DECIMAL NUMERIC PROGRAM DATA> (or <NRf>)

This data type includes <NR1>, <NR2> and <NR3> data types. It will

be used for decimal fractions with or without an exponent. Instruments

will adapt the values they receive to fit their degree of precision. For

example, if an instrument has a precision of two digits after the

decimal point and the incoming value is 12.048, this value will be

rounded off to 12.05.

The second diagram below illustrates the <mantissa> syntax.

The third diagram illustrates the <exponent> syntax.

Examples: +2.0 e5, –.56E+4, 6.5e–10
