Setting Programmable Pulse Mode
Use the “SET PROG. PULSE?” menu to set up one of the many pulse modes, in which you can
broadcast over one of the standard outputs (Port1, Port2, or Port3) at a predetermined interval or
rate. Also, there is a “PULSE PER DAY” mode and a “SINGLE TRIGGER” (or pulse per year)
mode. Programming includes adjusting the pulse width from a minimum of 10 milliseconds to 600
seconds, depending on your application. It also allows you to configure the pulse to occur at either
UTC or Local time where applicable.
Programmable pulses may also be configured to trigger the internal relay.
Remember to
consult with the relay specifications before using this mode as the relay has a limited lifetime.
See Section 12.3.4 for relay specifications.

Entering Numerical Values
When installing numerical values first use the UP/DOWN keys to change the digits and then
SETUP and ENTER to move the cursor left or right. Use the UP/DOWN keys for each digit and
ENTER as required. To complete the installation after you have configured the numerical value,
keep pressing the ENTER key to move the cursor to the right and exit the menu.
NOTE:
Single Trigger transitions from low to high, or high to low, and remains in that condition
until reset. Therefore, in single-trigger mode pulse width does not apply.
For RS-232 command, see Section 11.2.10

Auxiliary IRIG-B
One special mode that can be used in the programmable pulse feature is a separate instance of
unmodulated IRIG-B. If IRIG-B mode is selected, programmable pulses are disabled. Therefore,
if a separate instance of IRIG-B is required, make sure that the programmable pulse feature is not
needed. To use this separate instance of IRIG-B, make sure any of the ports used for this mode
have the respective jumper set to Prog Pulse. After setting the jumper(s), complete the setup in
the Utility, or as described in Section 8.8.5.
