Alignment Procedure 7 of 11

HONEYWELL CONFIDENTIAL
TX Driver and TX Final Alignment Procedures:
1. Set the IFR to ATCRBS.
2. Verify that R1 on the TX Final board and R3 on the TX Driver board are set fully CCW. Apply
unit power.
3. On the TX Driver board, measure the voltage at L4 (scope or voltmeter). Set this voltage to 4.5V
by adjusting R3 CW. Note that the total unit current draw at this time should be no more than
190ma.
4. On the TX Final board, attach scope probe to the junction of L11 and R16. Adjust R1 CW while
observing a positive pulse on the scope. Set this pulse height to 3.8 V (maximum is 4 V).
5. Adjust the scope to observe the 1st TX pulse. While observing this 1st pulse, on the TX Final
board, start by adjusting C27 first, then C44 and then C26 (in this order) for maximum TX
pulse power as observed on the scope and IFR Power Monitor. Also, observe this pulse and
adjust the three tuning caps slightly for the best Pulse Top flatness and Rise and Fall time
linearity.
6. Check the pulse Width measurement. It should be approximately 430nsec at this time. If not,
on the TX Driver board, adjust R4 (first) and then R30 to set the preliminary pulse width to
430ns. The pulse Rise time should be greater than 50ns and less than 100ns. The pulse Fall
time should be greater than 50ns and less than 170ns. Make minor readjustments to C27, C44,
and C26 on the TX Final board as necessary to bring the pulse Rise and Fall times within
specifications. Check the power output on the IFR display. It should be greater than 125W
minimum.
7. Set the scope delay to approximately 20.5usec and adjust as necessary to observe the last pulse
of the TX pulse train. Check the TX Pulse Width. It should be approximately 430nsec. If not,
make a slight adjustment to R4 then R30 on the driver board. Verify the pulse Rise and Fall
times are within the specifications listed above. If not, make minor adjustments to the TX
board tuning caps as necessary.
8. Set the IFR to Long Mode S.
9. Set up the scope to observe the first TX Pulse.
10. Check the pulse width measurement. It should be a minimum of 520 +/- 10nsec. If necessary,
on the TX Driver board, adjust R4 then R30 to set this pulse width to 520nsec. The pulse Rise
time should be greater than 50ns and less than 100ns. The pulse Fall time should be greater
than 50ns and less than 170ns. Again, if necessary, make minor readjustments to C27, C44,
and C26 on the TX Final board to bring the pulse Rise and Fall times within specifications.
Check the power output on the IFR display. It should be greater than 125W minimum.

11. Set the scope delay to approximately 119.5usec and adjust as necessary to observe the last
pulse of the TX pulse train. Check the pulse Width. It should be 520nsec +/- 10nsec.
Make minor adjustments to R4 then R30 if necessary. Verify that the pulse Rise and Fall
times are within the specifications listed above. If not, make minor adjustments to the TX
board tuning caps as necessary.
12. Check the TX Pulse Spectrum on the spectrum analyzer. With a Span of 1GHz, verify there
are no spurs on either side of the 1090Mhz TX pulse.
13. Measure the close-in TX Pulse Spectrum with the analyzer Span set to 50MHz and the RES
BW set to 300Khz. The spectrum observed should meet the TX Pulse Spectrum requirements
shown below on both the lower and upper side frequencies down from the 1090Mhz peak:
MHz difference from 1090mHz dB down from 1090Mhz peak
>1.3 to <7 Mhz 3dB or more
>7 to <23 Mhz 20dB or more
Increase span to 200Mhz. Set RES BW to 3Mhz.
>23 to <78 Mhz 40dB or more
Increase span to 500Mhz.
>78Mhz 60dB or more
14. Make slight adjustments if necessary to C26, C27, and C44 on the TX Final board to bring the
side lobes within specifications.
15. Set the IFR back to ATCRBS.
16. Set the Spectrum analyzer Span to 1Ghz and the RES BW back to 3Mhz.
17. Repeat all TX Pulse Spectrum tests as listed above on both sides of the 1090Mhz peak. Verify
the spectrum measurements are within specifications. Make minor TX tuning
adjustments only if necessary. Note: When testing spectrums >78Mhz in ATCRBS
reduce the RES BW to 1Mhz.
18. Repeat the pulse Width measurements on the first and last TX pulse. The pulse Width should
now be 450 +/- 100 ns. If not, make minor adjustments to R4 and R30 on the Driver board.
Check the pulse Rise and Fall times for the first and last TX pulse. Verify they are within
specifications (Ref step 6). Make only miner adjustments as necessary.
