Specifications

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 After *RST/Power-on, each element in the CVT contains the IEEE-754 value
“Not-a-number” (NaN). Elements specified in the DATA:CVT? command that have
not been written to be an algorithm will return the value 9.91E37.
·
*RST Condition: All elements of CVT contains IEEE-754 “Not a Number”.
·
Related Commands: SENS:DATA:CVT:RES, FORMAT:DATA
Usage SENS:DATA:CVT? (@10:13) Return algorithm values stored in CVT
elements 10 through 13
DATA:CVT? (@10,13) Return only element 10 and element 13
DATA:CVT? (@330:337,350,360) Return algorithm values from elements
330-337, 350 and 360
[SENSe:]DATA:CVTable:RESet
[SENSe:]DATA:CVTable:RESet sets all 502 Current Value Table entries to the
IEEE-754 “Not-a-number.”
Comments
·
The value of NaN is +9.910000E+037 (ASCII).
·
Executing DATA:CVT:RES while the module is INITiated will generate an error
3000, “Illegal while initiated.”
·
When Accepted: Not while INITiated
·
Related Commands: SENSE:DATA:CVT?
·
*RST Condition: SENSE:DATA:CVT:RESET
Usage SENSE:DATA:CVT:RESET Clear the Current Value Table
[SENSe:]DATA:FIFO[:ALL]?
[SENSe:]DATA:FIFO[:ALL]? returns all values remaining in the FIFO buffer
until all measurements are complete or until the number of values returned exceeds
FIFO buffer size (65,024).
Comments
·
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.
