TRACe<n>:IQ:DATA:MEMory? <OffsetSamples>,<NoOfSamples>
This command reads out previously acquired (and frequency response corrected) I/Q
data from the memory. Furthermore, the offset related to the start of measurement and
the number of I/Q samples are given. Thus, a previously acquired data set can be read
out in smaller portions. If no parameters are given, all data is read from the memory.
The maximum amount of available data depends on the settings of the TRACe<n>:
IQ:SET command, the output format on the settings in the FORMat subsystem.
The returned values are scaled linear in unit Volt and correspond to the voltage at the
RF or digital input of the instrument.
The format of the output buffer corresponds to the TRACe<n>:IQ:DATA command.
The command requires all response data to be read out completely before the instru-
ment accepts further commands.
If no I/Q data is available in memory because the corresponding measurement was not
started, the command causes a query error.
Note: For very large data amounts data processing may become very slow and for
record lengths >200 Ms, only the first 200 Ms can be retrieved using the TRACe<n>:
IQ:DATA:MEMory? command. Afterwards, the command may fail.

Parameters:
<OffsetSamples> Offset of the values to be read, in relation to the start of the
acquired data.
Range: 0 to <# of samples> – 1, with <# of samples> being
the value set by the "TRACe:IQ:SET" command
*RST: 0
<NoOfSamples> Number of measurement values to be read.
Range: 1 to <# of samples> - <offset samples> with <# of
samples> being the value set by the
"TRACe:IQ:SET" command
*RST: <# of samples>
