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: 1 PPS,
10 PPS, 100 PPS, 1 kPPS, 10 kPPS, 1 MPPS, 5 MPPS, 10 MPPS, or PPO. The default
factory setting is 10 MPPS.
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
page 204.
For J2 specifications, see
“J2 - Rate Out” on page 7
or
“J2 - Optional Programmable Pulse
Out (PPO)” on page 7
.
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 page 135
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.
