6.5 Data Formats
The 3511-50 uses character string data and decimal numeric data, and the
type used varies according to the command in question.
(1) Character data
Character string data must always begin with an alphabetic character, and
the characters following can be either alphabetic characters or numerals.
Although in character data either upper case letters or lower case letters are
accepted, response messages output by the 3511-50 are always in upper case
letters.
Example :TRIGger inT
(2) Decimal data
The numeric data values are all represented in decimal, in three formats
identified as NR1, NR2 and NR3, and each of these can appear as either a
signed number or an unsigned number. Unsigned numbers are taken as
positive. Further, if the accuracy of a numerical value exceeds the limit
which the 3511-50 can deal, it is rounded off (5 and above is rounded up; 4
and below is rounded down).
NR1 format: Integer data
Examples
+12, -23, 34
NR2 format: Fixed point numbers
Examples +1.23, -23.45, 3.456
NR3 format: Floating point numbers.
Examples
+1E-2, -2.3E+4
The term "NRf format" includes all these three formats. When the 3511-50
is receiving it accepts NRf format, but when it is sending response messages
it utilizes whichever one of the formats NR1 to NR3 is indicated in the
specified command.
Examples
:RANGe 6
:RANGe +6.012
:RANGe 0.0006E4
