(4) Set DBM control to +7 dBm and adjust synthesized signal generator power
output until SET POWER meter indicates SET POWER.
(5) Connect equipment as shown in figure 2, connection B. Power meter indication
will be between +5.5 and +8.5 dBm.
(6) Repeat technique (1) through (5) for highest possible level allowed by synthesized
signal generator or cardinal point on TI dBm dial (whichever is possible).
(7) Repeat technique of (1) through (6) above at frequencies of 9.05 and 9.60 GHz
(16.35 and 16.9 GHz).
b. Adjustments. No adjustments can be made; however, a new calibration chart will
be prepared and attached to TI if necessary.
12. Attenuation Dial Accuracy
a. Performance Check
(1) Connect equipment as shown in figure 3.
Figure 3. Attenuation - equipment setup.
(2) Set dBm dial to +10 dBm.
(3) Set TRAN/TEST/RECV switch to TEST (red dot) position and adjust PHASE
control for maximum peak indication of SET POWER meter. Adjust POWER SET control
as necessary to maintain on-scale indication.
NOTE
The PHASE control has several settings at which peak
deflection can be obtained on the power meter. Select the
setting that provides the most stable operation.
