11. Input Power Accuracy
a. Performance Check
(1) Set TRAN/TEST/RECV switch to TRAN and adjust SET ZERO COARSE and
FINE controls to obtain SET ZERO indication on SET POWER meter.
(2) Connect equipment as shown in figure 2, connection A.
Figure 2. Input - equipment setup.
(3) Adjust controls of microwave measurement system (A2) for CW operation at 8.5
GHz (15.8 GHz) and power level for an on-scale Indication on SET POWER meter.
(4) Set DBM control to +7 dBm and adjust microwave measurement system power
output until SET POWER meter indicates SET POWER.
(5) Connect equipment as shown in figure 2, connection B.
Power meter (A3)
indication will be between +5.5 and +8.5 dBm.
(6) Repeat technique (1) through (5) for highest possible level allowed by microwave
measurement system or cardinal point on 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).
