(7) Set signal generator frequency to 10 MHz and level output to -30 dBm. If TI
does not display a stable indication of applied frequency, perform b below.
(8) Adjust signal generator frequency from 10 to 500 MHz. If TI does not display a
stable indication of applied frequency, perform b below.
(9) Set signal generator frequency to 500 MHz and level output to -35 dBm. If TI
does not display a stable indication of applied frequency, perform b below.
(10) Adjust signal generator frequency from 500 MHz to 10 GHz. If TI does not
display a stable indication of applied frequency, perform b below.
(11) Set signal generator frequency to 10 GHz and level output to -25 dBm. If TI
does not display a stable indication of applied frequency, perform b below.
(12) Adjust signal generator frequency from 10 to 18 GHz. If TI does display a stable
indication of applied frequency, perform b below.
(13) Set RANGE switch to 250 MHz - 18 GHz.
(14) Set signal generator frequency to 250 MHz and level output to -30 dBm. TI will
display a stable indication of applied frequency.
(15) Adjust signal generator frequency from 250 to 500 MHz. TI will display a stable
indication of applied frequency.
(16) Set signal generator frequency to 500 MHz and level output to -35 dBm. TI will
display a stable indication of applied frequency.
(17) Adjust signal generator frequency from 500 MHz to 10 GHz. TI will display a
stable indication of applied frequency.
(18) Set signal generator frequency to 10 GHz and level output to -25 dBm. TI will
display a stable indication of applied frequency.
(19) Adjust signal generator frequency from 10 GHz to 18 GHz. TI will display a
stable indication of applied frequency.
b. Adjustments
(1) Connect signal generator RF Output to TI INPUT 50ΩΩ.
(2) Set signal generator frequency to 100 MHz and level output to -25 dBm.
(3) Adjust A17A1R22 (fig. 1) fully ccw.
(4) Adjust A17A1R11 (fig. 1) for a stable indication on TI.
(5) Decrease signal generator level output and adjust A17A1R11 (fig. 1) until
maximum sensitivity is obtained (R).
(6) Increase signal generator level output for a stable indication. Record signal
generator level output indication.
(7) Adjust A17A1R22 (fig. 1) fully cw. TI will display all zeros.
