Data Format - Decimal Numeric Program Data
Data Formats
Both RS-232 and GPIB share the same data formats except as noted. Many of the
<PROGRAM MESSAGE UNITS> and <RESPONSE MESSAGE UNITS> include numeric data
in the message, e.g., the '0' in the message
SINE 0 . This section defines acceptable data formats,
and the complete command listing in chapter 7 indicates which formats are used with specific com-
mands and responses.
DECIMAL NUMERIC PROGARM DATA or <NRf>
This is the most flexible of the numeric representations and takes the following general form:
where <mantissa> = [±][ x...x ][ .x...x ] with a maximum length of 255 characters (excluding leading
zeros), and the optional <exponent> = E[±][x...x] or e[±][x...x] with a maximum value of ±32000.
Note in the above defmitions: x represents digits 0-9
[ ] means enclosed characters are optional
The following example demonstrates several acceptable ways to represent the number 1,234,567,890 in
<NRf> format:
+1234567890 123456.7890 <white space> e04
1.2349 +.123410
Three other numeric data formats are used in <RESPONSE MESSAGE UNITS>, and are subsets of the
more general <NRf> format.
<NR1 NUMERIC RESPONSE DATA> or <NR1> -
[±][x...x] e.g. -98765432
<NR2 NUMERIC RESPONSE DATA> or <NR2> -
[±]x[x...x].x[x...x] e.g. +98765.432
<NR3 NUMERIC RESPONSE DATA> or <NR3> -
[±]x[x...x].x[x...x]E±x[x..x] e.g. 987.05
<NON-DECIMAL NUMERIC PROGRAM DATA> -
Numeric values may also be represented as a binary, octal, or hex number, as follows:
Binary -
#Bx[x...x] or #bx[x...x] where x is a 0 or 1
Octal - #Qx[x...x] or #qx[x...x] where x is a 0 through 7
Hex - #Hx[x...x] or #hx[x...x] where x is a 0 through F
