TL1 Command Interface
RTRV-DATA-TDEV:[tid]:aid:ctag
[::[clksrc][,start][,stop]];
Valid aid code:
S1Ay-z
This command returns TDEV data for an input port. This
command requires an aid to identify the input port to report
data from. It then has the ctag and a null field followed by
optional parameters which contain a clock identifier clksrc
[CLK-A|CLK-B] and the start and stop times for the
measurement. If no clock source is specified, the current
output clock is used. The response is the complied message
followed by the requested data. The format for each
response message line is:
^^^"aid:ocrdat,ocrtm,TDEV,clksrc,temper,monval”
<cr lf>
where:
ocrdat
and
ocrtm
= the beginning date and time the data
was collected
clksrc
= clock used for the measurements
tmper
= time period for the measurement data, given in
seconds
monval
= data value for the time period, given in
nanoseconds. The maximum tmper values for TDEV are
0.1, 0.3, 0.6, 1.0, 3.0, 6.0, 10.0, 30.0, 60.0, 100.0, 300.0,
600.0, 1000.0, 3000.0, 6000.0, and 10000.0
start
= start time specifies the start date and time for
data in the format MM-DD,HH-MM. If the date is null but
followed by a time, the command defaults to the current
date. If the start time is null, but preceded by a date, the
command defaults to the current time. If the start date
and time are null, the command defaults to the start of the
data. The comma must be present to indicate a null start
time.
stop
= stop time specifies the stop date and time for data
in the format MM-DD,HH-MM. If the date is null but
followed by a time, the command defaults to the current
date. If the stop time is null but preceded by a date, the
command defaults to the current time. If the stop date
and time is null, the command defaults to the end of the
data.
Only the values available in the interval between the start
and stop times is output.
