AUX
The AUX I/O is used as a port for a variety of functions:
Event - If the option for an event input is enabled, the AUX input activates an
event time/position stamp. 3.3Vdc CMOS. Event is a rising/falling edge, as
determined by edge direction command.
PWM Frequency Output - the NR300 has the capability of generating a variety of
frequencies, programmable by $AUXFR command.
IRIG-B Unmodulated - Provides an unmodulated pulse output that conforms to
the IEEE 1344 standard. The IRIG output is synchronized to the Rb PPS, such
that GPS lock and holdover are consistent across the IRIG outputs. The
synchronization of the IRIG-B DCLS to the Rb pulse is <1us.
Output of AUX BNC is selectable between IRIG-B or PWM output on the USER
SETTINGS menu.
For event input, the function of the AUX must be configured at the factory.
IRIG-B Sine
The IRIG-B Sine output provides a 1kHz modulated sine output that conforms to
the IEEE 1344 standard. The IRIG output is synchronized to the Rb PPS, such
that GPS lock and holdover are consistent across the IRIG outputs.
