9. Sensitivity
a. Performance Check
(1) Set function generator as listed in (a) through (d) below:
Function Outputs to 50Ω.
(a)
Function to sine wave.
(b)
Frequency to 10 Hz.
(c)
Amplitude to 0.001 VPP.
(d)
(2) Position TI controls as listed in (a) through (f) below:
CHANNEL A LEVEL control to PRESET.
(a)
CHANNEL A SLOPE switch to +.
(b)
CHANNEL A 50Ω/1MΩ switch to 50Ω.
(c)
CHANNEL A ATTEN X1/X10 switch to X1.
(d)
CHANNEL A AC/DC switch to DC.
(e)
CHECK/COM A/SEP switch to SEP.
(f)
(3) Connect TI CHANNEL A input to function generator Function Output
Unbalanced.
(4) Press the function generator Enter key to enable the knob, and slowly rotate the
function generator knob cw until TI display GATE light flashes and indication is stable at
approximately 10 Hz.
(5) Verify that the function generator indicates within limits specified in table 3. If
not perform b below.
(6) Repeat technique of (1) through (5) above for remaining settings listed in table 3.
