(5) Reconnect 115 V power cord to TI.
(6) Press TI POWER ON/DISABLE key to ON.
(7) Press TI pushbuttons as listed in (a) through (l) below:
CHANNEL A.
(a)
Vhigh and enter 1.0 from data keyboard and press ENTER/Hz.
(b)
Vlow and enter 0 from the data keyboard and press ENTER/Hz.
(c)
Lead and enter .9 from data keyboard and press n/GHz.
(d)
Trail and enter .9 from data keyboard and press n/GHz.
(e)
Per and enter 100 from data keyboard and press n/GHz.
(f)
Wid and enter 1 from data keyboard and press /MHz.
(g)
Trigger Impedance 50.
(h)
Trigger Level 0.1.
(i)
Trigger Slope positive.
(j)
Trigger Mode single.
(k)
Press DISABLE pushbutton (model 9211 output module) to on (red light
(l)
extinguished).
(8) Set up function/arbitrary generator for an output of 1.00 Vpp 100 kHz
square wave.
(9) Set oscilloscope Vertical 1 and Vertical 2 input impedance to 50 .
(10) Adjust oscilloscope controls to obtain a satisfactory dual two-channel display on
the crt.
(11) Rotate TI FINE CONTROL KNOB clockwise, increasing the trigger level.
Record the level at which the waveform disappears. Reset the trigger level to 0.10 V.
(12) Rotate TI FINE CONTROL KNOB counterclockwise, decreasing the trigger
level. Record the level at which the waveform disappears. Reset trigger level to 0.10 V.
(13) Add the results of (11) and (12) above. Divide this value by two and subtract the
result from the value recorded in step (11). Rotate TI FINE CONTROL KNOB to adjust
trigger level to this new value.
(14) Adjust R66 (fig. 5) until Vertical 2 waveform just disappears (R).
(15) Using TI FINE CONTROL KNOB adjust trigger level to 0.52 V.
(16) Adjust C11 (fig. 5) to the point that the waveform just disappears (R).
(17) Press TI POWER ON/DISABLE key to DISABLE.
(18) Disconnect 115 V power cord from TI.
(19) Reinstall power supply module in TI chassis.
(20) Replace TI top cover.
(21) Reconnect 115 V power cord to TI.
(22) Press TI POWER ON/DISABLE key to ON.
