3 PRELIMINARY OPERATIONS:
3.1 Review and become familiar with the entire procedure before beginning the 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.
8
T.O. 33K4-4-669-1
3.2 Connect test equipment to appropriate power source. Set POWER switches to ON or STBY and allow a warm-up period as required by the manufacturer.
3.3 Connect the TI to appropriate power source. Set TI ON STANDBY switch to ON and allow a 30 minute warm-up.
3.4 Due to lack of standards, annotate and attach a Limited Certification Label stating TI Sweep (Analyzer Mode) not calibrated <0.1 ms.
3.5 Make a copy of Tables 20 and 21 to be used in the Calibration Process.
3.6 TI with Option ESIB-B2, Preamplification, extends the frequency range for preamplification to 26.5 GHz or 40 GHz, as applicable.
4 CALIBRATION PROCESS:
NOTE
Unless otherwise specified, verify the results of each test and take corrective action whenever the test requirement is not met, before proceeding.
4.1 INTERNAL REFERENCE FREQUENCY CALIBRATION:
NOTE
Adjustment of the Time Base Oscillator is normal due to the Aging Rate of the crystals. This is common to all Quartz Oscillators. The adjustment actions taken during this calibration will ensure the greatest reliability of the TI by adjusting the time base reference to the nominal value each time it is calibrated.
4.1.1 Connect Frequency Standard 10 MHz REF OUT to the Electronic Counter EXT FREQ STD INPUT (1-10 MHz). Set Electronic Counter INT STD/EXT STD switch to EXT STD.
4.1.2 Connect TI EXT REF IN/OUT (rear panel) to the Electronic Counter CHANNEL A Input. Set the Electronic Counter 50Ω/1MΩ switch to 50Ω.
4.1.3 On the TI, press CONFIGURATION SETUP and REFERENCE INT/EXT, ensure that INT is selected.
4.1.4 Adjust Electronic Counter controls as required for a stable display indication, then push RESET.
NOTE
The values in the following step are derived from multiplication of the Aging Rate to determine the offset at one year. Use these calculated one year values regardless of the length of the calibration interval for this TI in T.O. 33K-1-100-1/2. The longest aging rate specification not to exceed 1 year has been used to calculate the limits.
4.1.5 Verify the Electronic Counter indication is 9 999 998 to 10 000 002 Hz.
4.1.6 To ensure reliability of the TI, the following action will be taken: If TI passed the above steps, perform the applicable adjustment steps in Appendix A, and enter NO ADJUSTMENT ACTION into the Maintenance Data Collection System. If TI failed, perform the applicable steps listed in Appendix A and enter appropriate ADJUSTMENT ACTION into the Maintenance Data Collection System.

4.4.2 Set the Signal Generator for 498 MHz at 0 dBm.
4.4.3 Set TI controls as follows:
SYSTEM PRESET
MENU ⇑ ANALYZER
CONFIGURATION SETUP REFERENCE INT/EXT, so INT is
highlighted
INPUT RF ATTEN MANUAL, then 1, 0
dB
LEVEL REF/UNIT UNIT, the dBm
LEVEL REF/UNIT REF LEVEL, then 0, dBm
13
T.O. 33K4-4-669-1
FREQUENCY CENTER/FREQ 4, 9, 8 MHz
SWEEP COUPLING/RUN COUPLING RATIO, then RBW/VBW NOISE [10]
4.4.4 Press TI FREQUENCY SPAN/ZOOM, then with the DATA ENTRY keys enter the first value listed in the TI Span column of Table 4.
4.4.5 Press TI SWEEP COUPLING, RES BW MANUAL, then with the DATA ENTRY keys enter the first value listed in the TI Res BW column of Table 4.
4.4.6 Press TI TRACE 1, then press AVERAGE.
4.4.7 Press TI TRACE 1, SWEEP COUNT, then 2, Hz and wait for the completion of 2 sweeps.
4.4.8 Press TI MARKER NORMAL.
4.4.9 Press TI MARKER SEARCH, then press PEAK.
4.4.10 Press TI LEVEL REF/UNIT, then with the DATA ENTRY keys enter the first value listed in the TI Ref Level column of Table 4.
4.4.11 Press TI INPUT, RF ATTEN MANUAL, then with the DATA ENTRY keys enter the first value listed in the TI Atten column of Table 4.
4.4.12 Press TI MARKER DELTA, PHASE NOISE and enter the offset listed in the Offset column of Table 4.
NOTE
Ensure the TI delta marker is not on a spurious signal when making the following measurement.
4.4.13 Verify the TI Delta 1 [T1 NOI] readout indicates within the values listed in the Limits column of Table 4.
Table 4.

4.4.14 Repeat steps 4.4.3 through 4.4.13 for the remaining values in Table 4.
4.4.15 Set the Signal Generator for minimum output and disconnect the test setup.
