How can I Programatically Retrieve All 500 Harmonic Order Measurements on the WT1800 / WT1800E?

To programmatically read all 500 harmonic orders measurement values, please use the ":NUMERIC:LIST" command set.

The maximum number of items for the :NUMERIC:LIST:VALUE? command is 64.
However, 1 LIST ITEM can transfer maximum of 502 data values including Total, DC, and from 1st order to the 500th order.
Therefore, if you send the :NUMERIC:LIST VALUE? command to read back all 64 items, the maximum number of data values that will be sent back will be 502 * 64 = 32,128 data values.

Please refer to the attached file taken from the Communications Interface Manual.
