e.
turn on (check) Annotations. There should be four dashed horizontal
lines, with the top and bottom lines superimposed on the high and low
levels of the waveform, showing that the high and low references are
properly set for rise time measurement.
f.
turn off (uncheck) Annotations.
5. In the Acq Setup dialog box, set Stop After to Run/Stop Button Only.
6. Press the CLEAR DATA button.
7. Press the RUN/STOP button to start acquisition.
8. Use the knobs in the front panel HORIZONTAL section to change the Scale
to 10 ps/division, while adjusting the Position to keep the first rising edge of
the step waveform centered on the display.
9. Press CLEAR DATA.
10. After about 20 seconds, note the Mean value of the Rise measurement. This
is T
sys
, the system rise time which is a combination of the step generator
and the 80E0X module rise times.
11. Calculate T
mod
, the 80E0X module rise time as follows:
T
mod
+
T
2
sys
- T
2
gen
Ǹ
Where T
gen
is the step generator rise time.
12. Check that T mod meets the tolerances in Table 4–4.
13. Repeat the Setup and Test sections for Channel 2.
