14. High Amplitude Risetime
a. Performance Check
f
(1) Connect oscilloscope Vertical 1 input to TI AMPL OUTPUT, using 50
eedthrough termination.
(2) Turn TI PULSE AMPLITUDE control fully counterclockwise and set mode
switch to HIGH AMPL.
(3) Adjust oscilloscope controls and TI PULSE AMPLITUDE control as required to
obtain a stable waveform. The leading edge aberrations during the first 50 nanoseconds
will be within 2 percent of the peak-to-peak amplitude or 50 millivolts, whichever is greater.
(4) Measure risetime. Risetime will be 10 nanoseconds or less.
b. Adjustments. No adjustments can be made.
15. Power Supply
a. Performance Check
NOTE
Do not perform power supply check if all other parameters are
within tolerance.
(1) Position TI controls as listed in (a) through (c) below.
(a) Mode switch to FAST RISE.
(b) AMPLITUDE switch to 10 volts.
(c) DC
SWITCH (internal (fig. 1)) switch to DC (up) position
(2) Connect multimeter between positive and negative 16.5 volts TEST POINTS
(fig. l). If multimeter does not indicate between 31 and 35 V dc, perform b below.
b. Adjustments. Adjust R30 (fig. 1) until multimeter indicates 33.00 V dc (R).
16. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
