(7) Press RECALL key and enter data 4 on keyboard. Adjust A4R7 (fig. 3) for
power meter indication of +9.0 dBm (R).
(8) Press RECALL key and enter data 5 on keyboard. If power meter does not
indicate +9.0 dBm readjust A4R7 for power meter indication of one-half the difference from
+9.0 dBm (example: power meter indicates +8.8 dBm, readjust +8.9 dBm).
(9) Disconnect power meter from TI and connect attenuator to RF OUTPUT.
Connect power meter to attenuator.
(10) Press RECALL key and enter data 6 on keyboard. Adjust A4R2 (fig. 3) for
power meter (plus attenuator value) indication of +13.0 dBm (R).
(11) Press RECALL key and enter data 7 on keyboard. If power meter (plus
attenuator value) does not indicate +13.0 dBm readjust A4R2 for one-half the difference
from +13.0 dBm.
(12) Press RECALL key and enter data 1 on keyboard. Repeat (3) through (11)
above until no further adjustment is required.
(13) Press function keys and enter corresponding data on keyboard as listed in as
listed in (a) and (b) below:
(a) CW key, DATA ENTRY 2.2 GHz.
(b) POWER LEVEL key, DATA ENTRY 0 dBm.
(14) Record power meter indication.
(15) Adjust FREQUENCY VERNIER control to tune TI output frequency to the
start of Band 2 (approximately 2.5 GHz).
NOTE
When performing (15) above a sharp drop in power meter
indication will be observed at the end of band 1 (band
breakpoint). Continue to manually tune TI output frequency
until power meter indication returns.
(16) Adjust A4R5 (fig. 3) for power meter indication equal to value recorded in (14)
above (R).
(17) Press RECALL key and enter data 5 on keyboard. Record power meter indication.
(18) Repeat (15) above.
(19) Adjust A4R8 (fig. 3) for power meter indication equal to value recorded in (17)
above (R).
(20) Press RECALL key and enter data 7 on keyboard. Record power meter indication.
(21) Repeat (15) above.
(22) Adjust A4R3 (fig. 3) for power meter indication equal to value recorded in (20)
above (R).
(23) Connect SWEEP OUTPUT to oscilloscope CH2 input.
(24) Connect semiconductor device to RF OUTPUT and connect oscilloscope CH1
input to semiconductor device.
