F111 – J2 Output (Rate, PPO)
F111 – J2 Output (Rate, PPO)
Use function F111 to configure the J2 Output to generate one of several rates or, optionally,
a Programmable Pulse Output (PPO). F111 selects from one of the following rates: 1PPS,
10PPS, 100PPS, 1kPPS, 10kPPS, 1MPPS, 5MPPS, 10MPPS, or PPO. The default
factory setting is 10MPPS.
Note: PPO is an optional feature. If purchased at the same time as the XL-GPS, it comes
enabled on the system. To purchase this option after you have purchased the XL-
GPS, contact Symmetricom Sales. See “H: Sales and Customer Assistance” on
page204.
For J2 specifications, see “J2 - Rate Out” on page7 or “J2 - Optional Programmable Pulse
Out (PPO)” on page7.
See "Factory Default Jumper and Switch Settings for Options" on page 166
Notes on F111 PPO:
• PPO can provide a single pulse output or repetitive pulse outputs.
• PPO can start and stop the pulse at any time in the year, with a resolution of one
microsecond.
• The repetition rates from PPO are based on "wildcards". See “Repetitive PPO pulse
outputs” on page135 regarding usage of "wildcards" to specify PPO repetition rates.
• PPO can provide the following sub-second repetition rates: 100 kPPS, 10 kPPS, 1
kPPS, 100 PPS, and 10 PPS.
• If PPO only specifies one time, it is the start time. The stop time is automatically set
for one microsecond later.
Keypad
To enter PPO wildcards from the keyboard, use the CLR key.
