(4) Set function generator amplitude to 141 mVp-p. Adjust function generator
frequency from 10 Hz to 10 MHz. If TI does not display a stable indication of applied
frequency, perform b below.
(5) Disconnect function generator and 50Ω feedthrough termination from TI.
(6) Connect signal generator RF Output to TI INPUT 1 MΩ Ω using a 50Ω
feedthrough termination.
(7) Set signal generator frequency to 10 MHz and level output to –50 dBm. Slowly
increase signal generator level output until TI displays a stable indication of applied frequency.
If signal generator level output exceeds –13 dBm, perform b below.
(8) Set signal generator level output
frequency from 10 to 250 MHz.
frequency, perform b below.
b. Adjustments
(1) Connect signal generator RF Output to TI INPUT 1 MΩ Ω using a 50Ω
feedthrough termination.
(2) Set signal generator frequency to 100 MHz and level output to –13 dBm.
(3) Press RESOLUTION Hz pushbutton to 100 and adjust A3R10 (fig. 1) until a
stable count is displayed (R).
11. 10 Hz to 18 GHz Frequency and 50Ω Ω Input Sensitivity Check
a. Performance Check
Do not exceed 1 W of power to 50Ω input, otherwise extensive
damage will occur to the test instrument.
(1) Connect function generator Function Outputs Unbalanced to TI INPUT
50Ω Ω .
(2) Set RANGE switch to 10 Hz - 18 GHz and press RESOLUTION Hz
pushbutton to 10.
Throughout the remainder of this check, press RESOLUTION
Hz pushbuttons as necessary.
(3) Set function generator for a sinewave, 10 Hz, 20 mVp-p, 50Ω output. If TI does
not display a stable indication of applied frequency, perform b below.
(4) Adjust function generator frequency from 10 Hz to 10 MHz. If TI does not
display a stable indication of applied frequency, perform b below.
(5) Disconnect function generator from TI.
(6) Connect signal generator RF Output to TI INPUT 50Ω Ω .
