Installation
Installation requires inserting the 1, 5, 10 MHz/MPPS card into an empty option slot in the rear of the XLi
Time and Frequency System. The card is supplied with mounting hardware. A Phillips screwdriver is the
1
only equipment needed.
Remove the cover plate of an empty option slot and save the screws. Slide the option card into the
guides on the side rails of the slot. Firmly press the card all the way in so it's connector engages the Bus
Backplane connector. When the connectors are engaged, the front of the card should be flush with the
adjacent surfaces. Using the previously saved screws, secure the card in the option slot.
Sine Wave Outputs
1, 5, and 10 MPPS back plane signals are discretely buffered and routed into the appropriate bandpass
filters. These filters select the desired sine component from the square waves. Pots [R9, R15, and R17]
set the amplitude of the 1, 5, and 10 MHz, respectively. The signals are then routed to Jumpers JP1,
JP2, JP3, and JP4 where they can be selected for input to the output drivers.
Square Wave Outputs
1, 5, and 10 MPPS signals are discretely buffered and routed to Jumpers JP1, JP2, JP3, and JP4, where
they can be selected for input to the output drivers.
Maintenance
This option has been designed to provide maintenance-free operation. Under normal use, it will require
no calibration of adjustment. Adjustment procedures are provided for uses only after repair. This section
contains troubleshooting techniques and adjustment procedures.
Equipment Required
The following test equipment is required for troubleshooting and adjustments:
•
Oscilloscope (100 MHz bandwidth)
•
Frequency Counter (10 MHz ±1 Hz)
•
AC Voltmeter
•
Spectrum Analyzer
•
Phillips-Head Screwdriver
•
Small Slot-Hear Screwdriver
•
Small Non-metallic Coil Adjustment Screwdriver
Symptoms of a malfunction fall into three broad categories:
•
No Output or Outputs
•
Noisy Outputs
•
Incorrect Frequencies
