3 PRELIMINARY OPERATIONS:

3.1 Review and become familiar with the entire procedure before beginning the Calibration Procedure.

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. If not strictly observed, could result in injury to, or death of, personnel or long term health hazards.

T.O. 33K3-4-3299-1

3.2Connect TI to appropriate power source. Set TI MAIN POWER CUTOFF switch (rear panel) to . Set TI POWER APPLIED/ON switch to ON.

3.3TI will initiate a Power-up Self Test. A normal functioning TI will beep twice and display the IFR logo briefly before entering the Center Frequency Operation Screen. If an error message is displayed or the TI fails to beep, this indicates an abnormal condition. If this occurs, set TI POWER APPLIED/ON switch to APPLIED, wait about 30 seconds, then switch to ON. If the error re-occurs, refer to appropriate Commercial Data for corrective action.

3.4Allow the TI a 15 minute warm-up period.

3.5Connect all test equipment to appropriate power source. Set all POWER switches to ON or STBY and allow a warm-up period as required by the manufacturer.

3.6This procedure identifies the Hardkeys in bold and the Softkeys (Menu keys) in Italics. Values shall be entered by use of the DATA key pad. For example: Press TI AMPLITUDE BW, RBW and set to 30 kHz. The AMPLITUDE BW key is a Hardkey, the RBW is a Softkey (Menu key), the 3 and 0 are entries using the DATA key pad, then push the kHz key which is also a part of the DATA keys.

3.7Perform TI Self Test as follows:

3.7.1Press TI MEMORY CONFIG, then DIAG.

3.7.2Using the TI , , and keys and the TI Control Knob, select the first test listed on the TI screen.

3.7.3Toggle TI SELECT until this appropriate test is listed as TEST on the TI screen.

3.7.4Repeat steps 3.7.2 and 3.7.3 for each remaining test listed on the TI screen.

3.7.5Press TI TEST.

3.7.6Once the TI is finished, verify that each test status indicates PASSED on the TI screen.

3.7.7Press TI RETURN, then RETURN again.

3.8 Make copies of Tables 11 through 20 and 23 through 25 for use as Calibration Worksheets.

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 REF OUT CALIBRATION:

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.

8

T.O. 33K3-4-3299-1

4.1.2 Connect TI REF OUT to the Electronic Counter CHANNEL A input. Set Electronic Counter 50 /1M switch to 50 .

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.

4.1.3Adjust Electronic Counter controls as required for a stable display indication and then push RESET. Verify Electronic Counter indication is 99 999 700 to 100 000 300 Hz 1 count of LSD if within the first year of service and 99 999 900 to 100 000 100 Hz 1 count of LSD thereafter for the STD TI or 99 999 900 to 100 000 100 Hz

1 count of LSD if within the first year of service 99 999 950 to 100 000 050 Hz 1 count of LSD thereafter for the AN930A OPT 09 TI.

4.1.4Set Electronic Counter INT STD/EXT STD switch to INT STD and disconnect test setup.

4.1.5To 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.

4.1.6Connect the TI REF OUT to the TI ANALYZER INPUT connector.

4.1.7Set the TI controls as follows:

FREQUENCY CENTER	100 MHz
AMPLITUDE SCALE	1 dB
FREQUENCY SPAN	200 kHz

4.1.8Using the TI Control Knob, adjust the TI gain to place the peak of the signal at a convenient reference line.

4.1.9Disconnect the cable from the TI REF OUT connector and connect to the Synthesized Sweeper RF OUT connector using the same cable.

4.1.10Set the Synthesized Sweeper to 100 MHz and adjust the output controls to place the peak of the signal at the same reference set in step 4.1.8. Do not change the Synthesized Sweeper output controls for the remainder of this para.

4.1.11Disconnect the cable from the Synthesized Sweeper.

4.1.12Standardize the Power Meter and Power Sensor (2.4).

4.1.13Connect the Power Sensor (2.4) to the Synthesized Sweeper.

4.1.14Verify the Power Meter indicates within -30.5 to -29.5 dBm.

4.1.15Set the Synthesized Sweeper for minimum output and disconnect test setup.
