(4) Set function generator amplitude to 71 mVp-p.
(5) Adjust function generator frequency from 10 Hz to 10 MHz. If TI does not
display a stable indication of applied frequency, perform b below.
(6) Disconnect function generator from TI.
(7) Connect signal generator RF Output to TI front panel BNC input.
(8) Set signal generator frequency to 10 MHz and level output to -19 dBm. TI will
indicate a stable indication of applied frequency.
(9) Adjust signal generator frequency from 10 MHz to 520 MHz. TI will display a
stable indication of applied frequency.
(10) Disconnect signal generator from TI.
(11) Set TI 50ΩΩ - 1 MΩΩ switch to 1 MΩΩ.
(12) Connect function generator Function Outputs Unbalanced to TI front panel
BNC input using a 50Ω feedthrough termination.
(13) Set function generator frequency to 10 Hz and amplitude to 1 mVp-p. Slowly
increase function generator amplitude until TI displays a stable indication of applied
frequency. Function generator amplitude will not exceed 141 mVp-p.
(14) Set function generator amplitude to 141 mVp-p.
(15) Adjust function generator frequency from 10 Hz to 10 MHz. TI will display a
stable indication of applied frequency.
(16) Disconnect function generator and 50Ω feedthrough termination from TI.
(17) Connect signal generator RF Output to TI front panel BNC input using a 50Ω
feedthrough termination.
(18) Set signal generator frequency to 10 MHz and level output to -13 dBm. TI will
display a stable indication of applied frequency.
(19) Adjust signal generator frequency from 10 to 25 MHz. TI will display a stable
indication of applied frequency.
b. Adjustments
(1) Set function generator frequency to 1 MHz and amplitude to 200 mVp-p.
(3) Decrease function generator amplitude while adjusting A3R8 (fig. 2) to a point
where TI no longer counts (R).
(4) Verify that sensitivity is at least 35 mVp-p.
