F123 – Have Quick Input/1 PPS Sync Configuration
Use F123 to configure or view the status of the Have Quick Input/1 PPS Sync option card (87-8016-3).
(See "HaveQuick/1 PPS Time and Frequency Reference(87-8016-3)" on page
The Have Quick/1PPS Time and Frequency Reference option card is a time and frequency reference for
synchronizing the XLi.
The Have Quick/1 PPS Sync card's two BNC connectors take separate Have Quick time code and
1 PPS inputs. F123's INPUT MODE determines how these inputs are used to synchronize the time:
• HAVE QUICK: The card gets major and minor time from the Have Quick time code input.
• 1PPS: The card gets minor time from the 1PPS input. Major time is determined by the XLi.
• HAVE QUICK 1PPS: The card gets major time from Have Quick time code input, and gets minor
time from the 1PPS input.
F123's HQ TIME REFERENCE setting identifies the Have Quick option card as a PRIMARY or
SECONDARY reference source for F74 CLOCK SOURCE CONTROL, or disables the card from being a
reference source when STANDBY is selected.
Note: Do not confuse the 1 PPS input connector on this card with other main clock 1PPS.
