Return values:
<argument> float
Return value:
Reads the current value of the O cursor or X cursor. The return
value is a pure numeric value without unit.The numeric value is
returned in the unit in which the Y-axis is displayed.

7.27 Transferring trace data
Transferring trace data from a controller via the IEC/IEEE bus to the Audio Analyzer
allows you to display externally generated or manipulated trace data with the graphical
display capabilities of the Audio Analyzer.
Example:
Assume that a fast frequency response measurement using a multisine signal and an
FFT has been programmed in a K1 macro. The FFT shows different high lines in the
multisine frequencies, with a noise floor between.
This is not the usual display mode of a frequency response curve.
The K1 macro now generates a sweep trace data set from the levels of the individual
bins and their frequency values. This data set is transferred to the Audio Analyzer and
is shown in the graphical display as a sweep trace, and thus as a frequency response
curve.
When transferring trace data, pure numeric values without units are transferred. Thus,
the presetting of the graph must precede the data transfer, and it determines the unit in
which the values are interpreted.
In the sweep subsystem, "X-Source" must be set to "Manual" before transfer of
X or Y data.
The Y-axes (…:AY and …:BY) can be transferred for all subsystems without
exception.
The transfer of data for the X-axis (…:AX and …:BX) is reserved exclusively for
the sweep subsystem.
The output of trace data with the
TRACe:<subsystem>:LOAD
commands is descri-
bed in Chapter 7.5.5, "Output of Trace Data Sets" , on page 738
