For example, to produce a repetitive 5 microsecond pulse occurring every 10 microseconds (i.e.,
repetitive pulses with 100 kPPS frequency with the start time or rising-edge on-time and the stop time or
falling-edge at 5
μS- or 10 μS pulse period with 5 μS pulse width), enter:
F111 PPO XXX:XX:XX:XX.XXXXX0 XXX:XX:XX:XX.XXXXX5<CR>
XL-GPS responds:
OK<CR><LF>
Or, for example, to produce a repetitive 50-microsecond pulse occurring every 100 microseconds (i.e.,
repetitive pulses with 10 kPPS frequency with the start time or rising-edge at 5
μS and the stop time or
falling-edge at 55
μS - or 100 μS pulse period with 50 μS pulse width), enter:

Or, for example, to produce a repetitive 50-microsecond pulse occurring every 100 milliseconds (i.e.,
