(5) Adjust signal generator frequency controls for 200 MHz output frequency and
amplitude controls for -30 dBm output.
(6) Adjust signal generator level controls for a 0.0 dBm indication on
measuring receiver.
(7) Turn signal generator RF output off disconnect cable at measuring receiver
of spectrum analyzer, then turn signal
power sensor and connect cable to INPUT 50
generator RF output on.
(8) Adjust spectrum analyzer controls to view TI fundamental, second, and third
harmonic signals on spectrum analyzer display. Second and third harmonic amplitudes
will be less than or equal to -30 dBm (30 dBm below carrier level indicated on spectrum
analyzer display.)
of
(9) Turn signal generator RF output off, disconnect cable from INPUT 50
spectrum analyzer and connect cable to measuring receiver power sensor, then turn signal
generator RF output on.
(10) Adjust signal generator frequency controls for 400 MHz output and amplitude
controls for a measuring receiver indication of 0.0 dBm.
(11) Repeat (7) and (8) above.
(12) Turn signal generator RF output off, disconnect cable connected to PRE-AMP
IN and reconnect to POWER AMP IN.
(13) Disconnect cable connected to PRE-AMP OUT and reconnect to POWER AMP
OUT, then turn signal generator RF output on.
(14) Adjust signal generator frequency controls for 200 MHz output.
(15) Adjust signal generator amplitude controls for a measuring receiver indication of
+8.0 dBm.
(16) Turn signal generator RF output off, disconnect cable from of measuring receiver
of spectrum analyzer, then turn signal
power sensor and connect cable to INPUT 50
generator RF output on.
(17) Adjust spectrum analyzer controls as necessary to view fundamental, second and
third harmonic signals on spectrum analyzer display. Second and third harmonic
amplitudes will be less than or equal to -30 dBm (30 dBm below carrier level indicated on
spectrum analyzer display).
(18) Turn signal generator RF output off, disconnect cable from INPUT 50 of
spectrum analyzer and connect cable to of measuring receiver power sensor, then turn
signal generator RF output on.
(19) Adjust signal generator frequency controls for 400 MHz output.
(20) Adjust signal generator amplitude controls for a measuring receiver indication of +8.0.
(21) Repeat (17) and (18) above.
(22) Disconnect all cables from TI.
b. Adjustments. No adjustments can be made.
