TABLE 3-3 SCPI COMMANDS AND QUERIES

Keyword Default Description
Value
FORMat Starts string format branch.
DATA Optional digital data identifier
:TALK HEX Sets talk string format. ASCII expresses a
byte's input bit pattern as a decimal value
equal to the binary sum of the input bits.
Multiple bytes are separated by commas.
See notes for an ASCII example. HEX
converts the two four-bit nibbles in an input
byte into the ASCII characters 0-9 and A-F
and places two characters into the GPIB
output buffer. HEXL is HEX format with a
comma inserted between input bytes.
TABLE allows the user to define his own
conversion table for converting input nibbles.
All strings end with a linefeed. BINary
places each input byte directly into the GPIB
output buffer without any conversion.
BINary output is terminated by asserting
EOI on the last character. Values are ASCii
| HEX | HEXL | TABLE | BINary.
TRANSlation 0123456789 Defines the HEX to ASCII conversion
:;<=>? used for TALK strings when the TABLE
format is selected. Value is a 16 character
string without separators. i.e.
012-.,E?
May not be concatenated with another
command.
LISTen Sets listen string and data output format.
ASCii converts a decimal value into an eight
bit binary bit pattern by bit weights. Mul-
tiple byte values are separated by commas.
HEX converts the incoming ASCII charac-
ters 0-9 and A-F into the equivalent four bit
HEX values. 4833 converts incoming ASCII
characters in the 30 - 3F ASCII subset (0-9
and :;<=>? ) into the equivalent four bit
HEX values as was done in ICS's Model
4833 Parallel Interface. HEXL allows the
