[SENSe:]DATA:FIFO[:ALL]?
all measurements are complete or until the number of values returned exceeds FIFO
buffer size (65,024).
•
DATA:FIFO? may be used to acquire all values (even while they are being
made) into a single large buffer, or can be used after one or more
DATA:FIFO:HALF? commands to return the remaining values from the
FIFO.
•
The format of values returned is set using the FORMat[:DATA] command.
Returned Value: ASCII values are returned in the form ±1.234567E±123.
•
For example 13.325 volts would be +1.3325000E+001. Each value is followed
by a comma (,). A line feed (LF) and End-Or-Identify (EOI) follow the last
value. The C-SCPI data type is a string array.
REAL 32, REAL 64, and PACK 64, values are returned in the
IEEE-488.2-1987 Indefinite Length Arbitrary Block Data format. This data
return format is explained in "Arbitrary Block Program and Response Data"
on page 160. For REAL 32, each value is 4 bytes in length (the C-SCPI data
type is a float32 array). For REAL 64 and PACK 64, each value is 8 bytes in
length (the C-SCPI data type is a float64 array).
Algorithm values which are a positive overvoltage return IEEE +INF and a negative
overvoltage return IEEE -INF (see Table 6-1 on page 207 for actual values for each
data format).
