2.5.14 4383A IRIG Input Card

This module has four input ports that can be used to recover time from an IRIG time source. Ports 1 and 2
support DC IRIG (Default B007) and Ports 3 and 4 support AM IRIG (Default B127). By default Port #1
is active, to select another source or IRIG format, use the

irig_input

command. If the IRIG Source does not

provide the year as part of the time code message, (i.e. B000/B120), the user can specify the year with the
command.

4380A>irig_input [slot#] [port#] [irig type] <year>

To verify the system settings, use settings hardware:slots:N where N = the slot # where the card is installed.

To verify the card is working properly, use the

status hardware:outputs:slots:N

command (N=Slot #) to

obtain the current status for a particular card. The selected IRIG Source will report as good, the other ports
will show as disabled.

Antenna Delay Calibration

Utilizing  the  4380A  as  a  precise  time  recovery  system  requires  a  complete  calibration  of  the  4380A  and
distribution system.  Cables and distribution equipment external to the  4380A affect the calibration of the
overall  system  and  will  result  in  an  offset  from  UTC(USNO).    This  section  assumes  the  on-time-point
(OTP) of the system is the rear panel outputs on the 4380A.  This may not be the desired location for the
OTP; users should refer to section 2.7  for information on changing the location of the OTP for the system.

For applications requiring the highest level of accuracy, the 4380A should be calibrated at Microsemi.  This
process  involves  installing  the  user’s  antenna  and  antenna  cable  at  the  factory  and  comparing  the  PPS
outputs  to  a  system  which  has  a  known  offset  to  UTC(USNO).    Once  the  calibration  is  complete,  the
antenna delay  value  is  provided to the customer  when  the  unit is delivered to the  user.    The PPS outputs
will  be  accurate  to  the  precise  calibration  levels  specified  in  Appendix  A  as  long  as  the  user  installs  the
antenna at a surveyed location.  If a surveyed antenna location is not available, the  4380A can be used to
survey the location.  See Section 2.4.5 on determining the antenna position.
