SyncSystem 4380A O&M Manual
Ch0 - Ch42 (20 event average): 8.418 ns 1276616399 S 595947 uS; sd: 0.052346 ns
Ch0 - Ch43 (20 event average): 15.995 ns 1276616399 S 597289 uS; sd: 0.053169 ns
Ch0 - Ch44 (20 event average): 15.712 ns 1276616399 S 598651 uS; sd: 0.067684 ns
The data fields are described below:
Ch0: 4380A internal 1PPS
ChXY: X = Slot #, Y = Port #.
(NN event averaging): Number of averages used to compute the results.
Note:
Typically the value of the
settings ptd_port
. This value may be different for a set of
measurements once the outputs are enabled, the user changes the averaging value, or the port is
connected or disconnected during the measurement period.
NN.NNN ns: Measurement results.
XXXXXXXXXX S: The second (from 1 Jan 1970) when the average was computed.
NNNNNNN uS: The fractional second the average was computed. This value plus the number of
seconds provides the time stamp when the average was computed.
sd: X.XXXXXX ns: Standard deviation of the measurement.
3.4.1.6 Raw TIC Data Port (2101)
This port provides users with raw measurement results from each of the 4393A TIC Cards installed in the
4380A. The measurements will only be available for the port(s) on the card(s) that detect a 1PPS input.
The measurements will automatically be output once per second.
Ch0 - Ch43 (1 event average): 16.042 ns 1276616720 S 134860 uS; sd: 0.000000 ns
Ch0 - Ch44 (1 event average): 15.698 ns 1276616720 S 171247 uS; sd: 0.000000 ns
Ch0 - Ch41 (1 event average): 7.917 ns 1276616720 S 234528 uS; sd: 0.000000 ns
Ch0 - Ch42 (1 event average): 8.469 ns 1276616720 S 272801 uS; sd: 0.000000 ns
Ch0 - Ch41 (1 event average): 7.917 ns 1276616721 S 131575 uS; sd: 0.000000 ns
Ch0 - Ch42 (1 event average): 8.367 ns 1276616721 S 147795 uS; sd: 0.000000 ns
Ch0 - Ch43 (1 event average): 16.042 ns 1276616721 S 161232 uS; sd: 0.000000 ns
Ch0 - Ch44 (1 event average): 15.698 ns 1276616721 S 193148 uS; sd: 0.000000 ns
The data fields are described below:
Ch0: 4380A internal 1PPS
ChXY: X = Slot #, Y = Port #.
(NN event averaging): Should always display 1 event average.
NN.NNN ns: Measurement results.
XXXXXXXXXX S: The second (from 1 Jan 1970) when the average was computed.
NNNNNNN uS: The fractional second the average was computed. This value plus the number of
seconds provides the time stamp when the average was computed.
sd: 0.00000 ns: Standard deviation should always be ZERO.
3.4.2 File Transfer Protocol (FTP)
Allows users to:
Obtain the FTP log files and the RINEX files. The gps log files are available in the ftp user’s
home directory and the rinex files are available in the rinex subdirectory. User name and
password = ftp. The ftp user has read and write access for the GPS log files and the ftp user can
delete the GPS log files as needed. The ftp user can get to the RINEX files using the change
directory command (
cd rinex)
and has read permissions but is unable delete the files in the rinex
subdirectory.
Upload a new software version (.iso) and use the
software_update
command to update the system
software. User name and password = update.
Manage the systems mibs files (SNMP)
