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 mS- or 10 mS pulse period with 5 mS pulse width), enter:

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 mS and the stop time or falling-edge at 55 mS - or 100 mS pulse period with 50 mS
pulse width), enter:
F111 PPO XXX:XX:XX:XX.XXXX05 XXX:XX:XX:XX.XXXX55<CR>
XL-GPS responds:
OK<CR><LF>
Or, for example, to produce a repetitive 50-microsecond pulse occurring every 100
milliseconds (i.e., repetitive pulses with 10 PPS frequency with the start time or rising-edge
at 5 mS and the stop time or falling-edge at 55 mS - or 100ms pulse period with 50 mS pulse
width), enter:
F111 PPO XXX:XX:XX:XX.X00005 XXX:XX:XX:XX.X00055<CR>
XL-GPS responds:
OK<CR><LF>
