c. Position controls as listed in (1) through (10) below:
(1) CHANNEL A and CHANNEL
B
TRIGGER
LEVEL/SENSITIVITY
pushbuttons pressed to SENSITIVITY.
(2) CHANNEL A TRIGGER LEVEL/SENS/SENS C control fully cw.
(3) CHANNEL B TRIGGER LEVEL/SENS control fully cw.
(4) CHANNEL A and CHANNEL B AC/DC pushbuttons pressed to DC.
(5) CHANNEL A and CHANNEL B ATTN X1/X20 pushbuttons released to X1.
(6) FILTER NORM/100 kHz pushbutton released to NORM.
(7) SEP/COM A pushbutton released to SEP.
(8) GATE TIME/DELAY control fully ccw but not into detent.
(9) Blue function shift pushbutton released (out).
(10) FREQ A pushbutton pressed.
8. Sensitivity Channel A and B
a. Performance Check
(1) Connect function generator Function Outputs Unbalanced to TI INPUT A
using 50 feedthrough termination.
(2) Set function generator for a sine wave, 10 Hz, 1 mVp-p, 50 output. Increase
function generator amplitude until TI displays a stable indication of applied frequency.
Function generator amplitude will not exceed 28 mVp-p.
(3) Repeat (2) above for frequencies from 10 Hz to 10 MHz.
(4) Release CHANNEL A AC/DC pushbutton to AC.
(5) Repeat (2) above for frequencies from 30 Hz to 10 MHz.
(6) Press CHANNEL A AC/DC pushbutton to DC.
(7) Disconnect function generator from TI.
(8) Connect signal generator OUTPUT RF to TI INPUT A using 50
feedthrough
termination.
(9) Set signal generator amplitude to 25 mV and adjust frequency from 10 MHz to
100 MHz. TI will display a stable indication of applied frequency.
(10) Disconnect signal generator from TI.
(11) Connect function generator Function Outputs Unbalanced to TI INPUT A
using 50 feedthrough termination.
(12) Press RATIO A/B pushbutton and press SEP/COM A pushbutton to COM A.
NOTE
TI will indicate 1.0 to 1.0000000 for (13) through (20) below
depending upon frequency selections.
