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
XL-GPS responds:
OK
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:
F111 PPO XXX:XX:XX:XX.XXXX05 XXX:XX:XX:XX.XXXX55
XL-GPS responds:
OK
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
μS and the stop time or
falling-edge at 55 μS - or 100ms pulse period with 50 μS pulse width), enter:
F111 PPO XXX:XX:XX:XX.X00005 XXX:XX:XX:XX.X00055
XL-GPS responds:
OK
Or, for example, to produce a repetitive one-minute pulse occurring every hour, enter:
F111 PPO XXX:XX:10:00.000000 XXX:XX:11:00.000000
XL-GPS responds:
OK
