a. Performance Check
(1) Connect OUTPUT to digitizing oscilloscope using PULSE HEAD and X10
attenuator. (Use a different Xl0 attenuator if not in tolerance.) Connect TRIGGER
OUTPUT to digitizing oscilloscope TRIG.
(2) Press pushbuttons as listed in (a) through (g) below:
(a) AMPLITUDE MODE AMPL MODE FAST EDGE.
(b) AMPLITUDE MODE EDGE POLARITY .
(c) AMPLITUDE MODE FREQ
to highlight 100 kHz.
(d) VARIABLE ON off.
(e) TRIGGER ON on.
(f) TRIGGER NORM.
(g) OUTPUT ON on.
(3) Press and hold FAST EDGE pushbutton until display indicates dL.
(4) Set digitizing oscilloscope probe attenuation to 10. Acquire signal using
digitizing oscilloscope.
(5) Perform Delta V measurement technique using digitizing oscilloscope, by placing
the Delta V markers on the upper and lower waveform peaks. Digitizing oscilloscope Delta
V will indicate between 1.045 and 1.155 V. Record Delta V indication.
(6) Press VARIABLE ON pushbutton on. Turn VAR dial (min/max) to vary pulse
amplitude indication on digitizing oscilloscope.
(7) Digitizing oscilloscope will indicate a pulse amplitude indication at least l0
percent of pulse amplitude recorded in (5) above.
(8) Press VARIABLE ON pushbutton off.
(9) Maintain setup and continue with next performance check.
b. Adjustments. No adjustments can be made.
a. Performance Check
(1) Acquire signal using digitizing oscilloscope.
(2) Perform risetime measurement technique using digitizing oscilloscope.
Digitizing oscilloscope will indicate a risetime measurement of ≤150 ps/D.
(3) Maintain setup and continue with next performance check.
b. Adjustments. No adjustments can be made.
NOTE
If any of the following aberration performance checks are not
within the limits specified, perform b below.
