Trace Data Transfer

This command transfers trace data from the instrument to the controller. Before executing this command, the instrument must be set to the desired measurement type.

In PIM vs. Time, Noise Floor – Time View, Noise Floor – Spectrum View, and Swept PIM measurement modes, a data point value of –160 dBm indicates an invalid value. In Distance-to-PIM mode, trace 1 and 2, a data point value of –200 dBm indicates an invalid value, and trace 3, a data point value of 100 dB indicates an invalid value.

The parameter X has a different meaning for each measurement mode. For PIM vs. Time, Noise Floor – Time View, and Noise Floor – Spectrum View, X should be NULL to retrieve trace data. For Distance-to-PIM, X must be 1 for the active trace, 2 for the DTP overlay trace, or 3 for the DTF overlay trace. For Swept PIM, X must be 1 for the Fixed F1 trace data, or 2 for the Fixed F2 trace data.

This command always returns data values in dBm for all measurement traces except trace 3 for Distance-to-PIM mode, which returns dB units.
