Export ASCII xDEV trace
Available in the Measurement → Allan Deviation ( a ), Measurement → Modified Allan
Deviation ( m ), Measurement → Hadamard Deviation ( h ), or Measurement → Time
Deviation (
t
)
views, this command creates an ASCII text file containing a
tau, sigma(tau)
value pair for each visible xDEV bin in the selected plot. One value pair is written per
line; each value is rendered with 16 digits of precision to the right of the decimal point.
The number and distribution of xDEV bins may be specified prior to acquisition with the
Bin Density field in the Frequency Stability tab of the acquisition dialog. Additionally,
the selected plot’s bin density may be adjusted after acquisition through the
Edit → Trace properties
dialog. See the help fields in these dialogs for details.
By default, the exported
tau, sigma(tau)
pairs will be saved with the suffix .CSV for ease
of reading into Excel and other spreadsheets.
Export ASCII AM/PM noise trace
Available in the Measurement → Phase noise ( P ) and Measurement → AM Noise ( A )
views, this command creates an ASCII text file containing
offset, dBc/Hz
values
corresponding to the visible noise trace for the selected plot. One value pair is written
per line; each value is rendered with 16 digits of precision to the right of the decimal
point.
One
offset, dBc/Hz
pair is written for each pixel column in the displayed graph. This
means that if you zoom in on a portion of the phase noise or AM noise graph, only the
trace data corresponding to the visible area of the selected plot will be exported.
Conversely, if the graticule’s X-axis boundaries extend beyond the minimum or
maximum offset for the selected plot, no
offset, dBc/Hz
pairs outside the valid range will
appear in the exported file.
By default, the exported
offset, dBc/Hz
pairs will be saved with the suffix .CSV for ease
of reading into Excel and other spreadsheets.
Note that when Show imaginary part of cross spectrum ( Ctrl-F3 ) is active, the
File → Export AM/PM noise trace command will export the imaginary cross spectrum
trace data rather than the normal AM noise or phase noise trace.
Export AM/PM spur table
Available in the Measurement → Phase noise ( P ) and Measurement → AM Noise ( A )
views, this command creates an ASCII text file containing
offset, dBc
values
corresponding to entries in the spur table for the selected plot. One value pair is
written per line; each value is rendered with 16 digits of precision to the right of the
decimal point.
See “Spurs” on page 72 for more about spur detection and measurement.
