<nrf value>
The symbol, <nrf value>, refers to the flexible numeric representation, as defined
by the IEEE-488.2 standard. This means is that numbers may be represented in
one of three forms, integer, floating point, or engineering/scientific notation. All of
the following are equal nrf values.
20, +20, 20.0, +20.0, 2.0E+1, +2.0E+1, 2.0e+1, +2.0e+1
<suffix unit>
The symbol, <suffix unit>, refers to the suffix program data that may follow an <nrf
value>. If the suffix is not used, the default suffix is assumed. The device
interprets any alpha characters following decimal data as a suffix without regard to
upper/lower case. Table 3.2 illustrates the suffixes used by the 6810B, including
default suffix values.
