Comments
·
Use the DATA:FIFO:COUNT? command to determine the number of values in
the FIFO buffer.
·
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 +1.3001. 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
Definite Length Arbitrary Block Data format. This data return format is explained
in “Arbitrary Block Program Data” on page 180 of this chapter. 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
).
NOTE
Algorithm values which are a positive overvoltage return IEEE +INF and a negative
overvoltage return IEEE -INF (see table on page 230 for actual values for each data
format).
