-
Field width, defines how many bits are used to encode the value.
It is possible to use less bits than the data encoding value would
require. For example, if 11 bits are used for an integer, only those
11 bits are stored in the binary report.
-
Do rounding after scaling, indicates that the value is rounded to
the nearest integer (after unit conversion and scaling).
-
Write absolute value of data, indicates that negative values are
multiplied by -1.
-
Write only sign of data, indicates that only a polarity bit is
displayed for data item. The polarity bit is zero if the data item is
equal to or more than zero (positive value of the data item).
Otherwise the polarity bit is one (negative value of the data item).
-
LSB written first, indicates that the number is displayed in a
reversed order (INTEL presentation).
-
Include parity bit, indicates that a parity bit is added to this field
to assure data validity. This option increases field length by one.
See below for a description of the parameter options:
For information on how to add a checksum, see section
. In binary reports, the CRC option
should be used instead of CRC_string.
There are also parameters that you can retrieve from the binary report
component in the Select Variables frame; see
Parameter Option
Description
Odd parity
If selected, odd parity is used; otherwise
even parity
Parity bit is written to MSB Indicates that the parity bit is the most
significant bit; otherwise the least
significant
