N.8 Frequency Synthesizer (86-708-1)
The N.8 Frequency Synthesizer card’s four independently programmable outputs generate pulse rates
from 8 kPPS through 8192 kPPS in 8 kPPS steps.
The N.8 Frequency Synthesizer is configured from the front panel keypad and command line interfaces
using F44 – N.8 Frequency Synthesizer (page 73)
. It can also be managed using the web interface.
Specifications
Installation
N.8 cards that were not factory installed in the XLi require additional installation if there will be more than
one Multicode or N.8 Frequency Synthesizer card in the XLi. Each card needs to have a unique card ID
number. The card ID number is set by changing the SW2 DIP switch settings. The unique card ID
number has no relation to the physical location of the card in the option bays. Changing the card ID
number is not required if there is only one Multicode/N.8 Frequency Synthesizer card, or if the cards in
the XLi were factory installed.
To set a unique card ID number, compare the SW2 DIP switch settings with those of the other Multicode/
N.8 Frequency Synthesizer cards present. Then set individual switches using the following table as a
guide:
Channels 4 Channels, independently programmable
Output Pulse Rates 8 kPPS through 8192 kPPS in 8 kPPS steps
(Factory setting: 8 kPPS)
Output Drive RS-422 into 50Ω
Wave Form Square wave
Synchronization Frequency locked to the XLi's internal 10 MHz oscillator
Connector Triax female (Trompeter BJ-77)
