:MMEMory:DATA:IQ
Syntax :MMEMory:DATA:IQ <file_name>,<flag>,<num>{,<i0>,<q0>…<in>,<qn>}
Description Save and download the IQ waveform data to the instrument
Parameter Name Type Explanation
<file_name> ASCII string
The name of the wave table file downloaded
into the instrument.
<flag> Discrete
When the IQ data file exceeds 64kB, you
should separately download the file package.
0—download the first data package;
1—download the subsequent packets;
2—download the last package and output
IQ waveform.
<num> Integer The number of IQ data pairs.
{,<i0>,<q0>
… <in>,<qn>} Decimal number
IQ data pairs. The maximum of each data
(e.g. i0) is two bytes.
Explanation When sending the command, you should add the data block starting with #9 flag to
represent the total length of the IQ data before <i0>,<q0>…<in>,<qn>. For
example, #9000000011 indicates the total length of the IQ data is 11 bytes. The
value is calculated by the formula (the bytes of IQ data pairs + the number of bytes
occupied by comma).
Example :MMEM:DATA:IQ test1,0,2,#9000000011 1,10,11,20
/*Save the current two pairs of IQ data with the test1 filename (the total length of
"1,10,11,20" is 11 bytes and expressed by #9000000011) and downloaded to
DSG3000*/
:MMEMory:DATA:IQ:LIST
Syntax :MMEMory:DATA:IQ:LIST?
Description Query the wave table file stored in the current root directory (D: disk) of the
instrument.
Return Format Return wave table file list. The format is "wave table filename (*.arb),file size". For
example,
16QAM.arb,16444,wave2.arb,16438,wave3.arb,16438,newwave.arb,16444,out3.arb
