half-full. This command provides a fast means of acquiring blocks of readings from
the buffer.
•
For acquiring data from continuous scans, your application needs to execute a
SENSe:DATA:FIFO:HALF?
up with the scan reading rate.
•
Use the SENSe:DATA:FIFO:ALL?
the FIFO buffer after the last scan has completed.
•
The format of readings returned is set using the
Returned Value: ASCII readings are returned in the form ±
•
For example 13.325 volts would be
followed by a comma (,). A line feed (LF) and End-Or-Identify (EOI) follow the
last reading. The C-SCPI data type returned is a string array.
REAL,32, REAL,64, and PACK,64, readings are returned in the
IEEE-488.2-1987 Definite Length Arbitrary Block Data format. This data return
format is explained in the " Arbitrary Block Program and Response Data" section
on page 156 of this chapter. For REAL,32, each reading is 4 bytes in length (the
C-SCPI data type returned is a float32 array). For REAL,64 and PACK,64, each
reading is 8 bytes in length (the C-SCPI data type returned is a float64 array).
Channel readings which are a positive overvoltage return
negative overvoltage return
values for each data format).
