TB 9-6625-2144-35
(3) Repeat technique of (1) and (2) above for frequency of 9.6 GHz (16.9 GHz). TI
signal generator will operate at 1 mW output level (power set indication) between 8.5 and
9.6 GHz (15.8 and 16.9 GHz).
b. Adjustments. No adjustments can be made. Failure to operate between 8.5 and
9.6 GHz (15.8 and 16.9 GHz) indicates TI klystron may need replacement.
10. Output Power Accuracy
a. Performance Check
(1) Set TRAN/TEST/RECV switch to TEST (red dot) position and DBM dial to +10
dBm.
(2) Adjust TI controls as described in 9a(1) and (2) above to set TI signal generator
to 8.5 GHz (15.8 GHz).
(3) Connect power meter (A3) to RF OUTPUT connector, using adapter (B2) for
AN/UPM-29 (*) and adapter (B1) for TS-147.
(4) Power meter indication will be between -8.5 and -11.5 dBm.
Record power
(5) Repeat (1) through (4) above for frequencies of 9.05 and 9.60 GHz (16.35 and
16.90 GHz).
NOTE
The value of attenuation on output cable assembly CG-92A/U
(supplied with TI) is accurate to 0.3 dB at 8.5, 9.080, and 9.6
GHz and is stamped on a metal tag which is attached to each
unit. Since attenuation of this cable may change with time,
actual attenuation of this cable should be confirmed by the
(6) Set up output power accuracy performance check as outlined in a above.
(7) Note power meter indication.
(8) Connect output cable assembly CG-92A/U between TI RF OUTPUT connector
and power meter, using adapter (B2).
(9) Repeat power test and note new power indication.
(10) The difference between the two readings will indicate actual cable attenuation
loss 0.3 dB.
b. Adjustments. No adjustments can be made, however, a new correction chart may
be prepared and attached to TI if necessary.
