The values reported by this command comprise a historical “strip chart” record of the
difference in phase between the nominal DUT input frequency reported by
show inputs
and the actual frequency at the DUT input jack, assuming that the reference frequency
is either a multiple of 100 kHz or has been set correctly with either
set referencefreq or
/referencefreq.
Entries for the past
n
seconds are displayed, ordered by age (oldest to
newest), where
n
defaults to 600 seconds. The value of
n
can be configured through the
use of the
/chart
command-line parameter.
