Connect power meter to TI RF OUTPUT.
(b)
(c)
Adjust synthesized signal generator level display to value recorded in (2) above.
(d)
Repeat (23) above, TI display will Indicate between -0.3 and +0.3 dBm.
(e)
Repeat (25) above, TI display will Indicate between -9.7 and -10.3 dBm.
(38) Connect equipment as shown in figure 3 with the following exception. Do not
connect 20 dB attenuator (fixed) in figure 3 equipment setup.
(39) Connect power meter to TI RF OUTPUT.
(40) Adjust synthesized signal generator frequency setting to 2 GHz.
(41) Adjust synthesized signal generator level controls for a TI POWER LEVEL
meter indication of 0.0 dBm.
