[SENSe:]DATA:ALL? <rdgs_per_channel> returns voltage formatted data from each active channel.

*(memory size in bytes)/(nbr of channels * 2) = 128M/4 or 128M/8 (MAX)

Readings Returned: The readings are returned in an array in an interleaved configuration. That is, the array contains the first reading from channel 1, channel 2, etc. This is followed by the second reading from channel 1, channel 2, etc.

NOTE This command can read the data from a measurement only once.

It is a destructive read and the data cannot be retrieved a second time.

Number of Readings Returned: The number of readings this command will return for each channel is determined by the number of samples set by SAMPle:COUNt. The total number of readings returned is the number of samples times the number of channels. If a measurement is aborted with ABORt, there may be less readings available than indicated by (samples x channels). For ABORted measurements, use DATA:COUNt? to determine how many readings are available.

Overloads and Deadlocks: A full scale reading may actually be an overload. A deadlock can occur when trigger events are set to BUS or HOLD because a software trigger could not break in after this command is sent.

PACKed Format Data: Data are returned as raw data (16-bit integers) when the data format is set to PACKed (see the FORMat[:DATA] PACKed command). To convert the raw readings to voltages, use voltage = reading

*range/32768 or voltage = reading * resolution (use [SENSe:]VOLTage [:DC]:RESolution? to obtain the resolution value).

REAL Format Data: Data are returned as real numbers when the data format is set to REAL (see FORMat[:DATA] REAL). The data are returned in voltage units and no scaling conversion is required as with the PACKed format. Readings are in an interleaved configuration.
