<unsigned_integer>
Number of y divisions in which the waveform
is displayed on the instrument screen.
<unsigned_integer>
Number of x divisions in which the waveform
is displayed on the instrument screen.
<float>
Number of units per y division.
<float>
Number of units per x division.
<binary_character>
Specifies in which scale the <y_scale> is set
by the instrument:
1 = 1-2-5 range
2 = 1-2-4 range
<binary_character>
Specifies in which scale the <x_scale> is set
by the instrument:
1 = 1-2-5 range
3 = record range
4 = variable range
<float>
Measurement value for the samples with value
zero (0) that you can see as offset value.
<float>
This field specifies the x-offset of the
first sample in <trace_samples>. (is time
between trigger moment and first sample.)
This field contains the value that
represents the step between two
consecutive sample values or in other
words the step per least significant bit.
This field contains the value (seconds)
that represents the distance between two
samples. (is time between two samples.)
In the case of an FFT-trace, this value
is the frequency of the fundamental (Hz).
