Numeric Program Data
Some command headers require program data to be expressed numerically.
For example, :TIMEBASE:RANGE requires the desired full- scale range to
be expressed numerically.
For numeric program data, you can use exponential notation or suffix
multipliers to indicate the numeric value. The following numbers are all
equal:
28 = 0.28E2 = 280E- 1 = 28000m = 0.028K = 28E- 3K
When a syntax definition specifies that a number is an integer, it means
that the number should be whole. Any fractional part is ignored and
truncated. Numeric data parameters that accept fractional values are
called real numbers.
All numbers are expected to be strings of ASCII characters.
• When sending the number 9, you would send a byte representing the
ASCII code for the character "9" (which is 57).
• A three- digit number like 102 would take up three bytes (ASCII codes
49, 48, and 50). The number of bytes is figured automatically when you
include the entire instruction in a string.
