Export ASCII phase data ( x )
This command is supported only when viewing the selected plot’s phase record
contents using
Measurement → Phase difference ( p ) or Measurement → Frequency-
difference (
f
)
. It will save an ASCII text file containing phase difference data in seconds,
one entry per line, at 16 digits of precision to the right of the decimal point.
If a selected or zoomed area has been defined by dragging with the mouse, only that
portion of the phase record will be exported.
By default, the exported phase data will be saved with the suffix .CSV for ease of reading
into Excel and other spreadsheets. Exported data may be re-imported into TimeLab, if
necessary, by the
File → Import ASCII phase or frequency data command. Select “All
files” as the file type if the data was not exported with the suffixes .TXT or .DAT, then
select
Phase difference (sec) as the file data type.
Optionally, each sample in the ASCII phase data file can be timestamped with its
absolute MJD or the number of elapsed seconds since the beginning of the phase
record.
Export ASCII frequency data (
X
)
This command is supported only when viewing the selected plot’s phase record
contents using
Measurement → Phase difference ( p ) or Measurement → Frequency-
difference ( f ) . It will save an ASCII text file containing absolute frequency readings in
hertz, one entry per line, at 16 digits of precision to the right of the decimal point.
If a selected or zoomed area has been defined by dragging with the mouse, only that
portion of the phase record will be exported.
By default, the exported frequency readings will be saved with the suffix .CSV for ease of
reading into Excel and other spreadsheets. Exported data may be re-imported into
TimeLab, if necessary, by the
File → Import ASCII phase or frequency data command.
Select “All files” as the file type if the data was not exported with the suffixes .TXT or
.DAT, then select
Frequency (Hz) as the file data type.
Optionally, each sample in the ASCII phase data file can be timestamped with its
