Clock Tools Help


----


ffp - Converts fractional frequency data to phase data

example: cat ffdata | ffp > phasedata


----


pff - Converts phase data to fractional frequency data

example: cat phasedata | pff > ffdata


----


scale - Scales fractional frequency or phase data by a factor of 10^-6

example: cat data | scale > scdata


----


ORDPhaseParser - Formats data generated by the ORD Tools for use with the Clock Tools

example: ordGen -o obsFile -e ephFile | ordClock | ORDPhaseParser > data


----


TIAPhaseParser - Formats data generated by the TSC 5110A Timing Interval Analyzer for use with the Clock Tools

example: cat tiadat | TIAPhaseParser > data


----


rmoutlier - Removes outlying data

example: cat data | rmoutlier > cleandata


----


dallandev - Computes the dynamic Allan deviation

example: cat data | dallandev <optional window size> <optional step size> > dallandata


----


mallandev - Computes the modified Allan deviation

example: cat data | mallandev > mallandata


----


nallandev - Computes the normal Allan deviation

example: cat data | nallandev > nallandata


----


oallandev - Computes the overlapping Allan deviation

example: cat data | oallandev > oallandata


----


ohadamarddev - Computes the overlapping Hadamard deviation

example: cat data | ohadamarddev > ohadamarddata


----


tallandev - Computes the total Allan deviation

example: cat data | tallandev > tallandata


----


allanplot - Plots deviation calculations on a log log plot

options:
-d increase the debug level
-t specifiy title
-l show legend
-s save to file
-c show 5071A cesium specification line line

example: cat allandevdata | allanplot -t "Allan Deviation" -l -c


----


ddevplot.m - Plots dynamic Allan deviation data

example: octave ddevplot.m


----


trunc - Truncates data after a specified time

example: cat oallandata | trunc 10000 > oallandatatrunc


----
