3 PRELIMINARY OPERATIONS:
3.1 Review and become familiar with entire procedure before beginning calibration process.
WARNING
Unless otherwise designated, and prior to beginning the Calibration Process, ensure that all test equipment voltage and/or current outputs are set to zero (0) or turned off, where applicable. Ensure that all equipment switches are set to the proper position before making connections or applying power.
3.2 Connect TI and test equipment to the appropiate power source, set POWER switches ON and allow a 1 hour
warm-up period.
3.3 TIME BASE AGING OFFSET CHECK:
3.3.1 TI must be plugged in for at least 24 hours before performing this test. Set TI rear panel INT OUT, EXT IN
switch to INT OUT.
3.3.2 Connect Frequency Standard 10 MHz FREQ OUT to Frequency Difference Meter (FDM) REF INPUT.
Connect TI rear panel REF (10 MHz) to the FDM SIG INPUT connector.
3.3.3 Standardize FDM as required. Set FDM METER RANGE switch as required for an on scale indication on
the Frequency Difference Meter.
4
T.O. 33K3-4-3119-1
3.3.4 If required adjust TI Oscillator FREQUENCY adjustment for the lowest possible Frequency Difference Meter Null readout. Verify Null is less than 2 X 10-8. Record the FDM reading along with the current time and date.
3.3.5 After 24 hours verify the reading on the Frequency Difference Meter is less than 2 X 10-8/day from the reading recorded in step 3.3.4.
NOTE
Adjustment of the TI Osc 10 MHz Time Base is normal due to the aging rate of the crystal. This is common to all Quartz Oscillators. NO REPAIR OR ADJUSTMENT ACTION should be entered into the Maintenance Data Collection System unless TI will not adjust to the minimum offset shown in Table 1, or step 3.3.5 fails.
3.3.6 If required, readjust TI Oscillator for the lowest possible Frequency Difference Meter Null indication and repeat step 3.3.5.
3.3.7 Disconnect Frequency Difference Meter from Frequency Standard and TI.
