„
Regard the first or last settings where the waveform is broken as the end
point of broken waveform. In other words, if you have already click
Start
of Broken Waveform , click End of Broken Waveform next.
„
If the waveform is broken with one set value only, and not across a range
of multiple settings, click both
Start of Broken Waveform and End of
Broken Waveform at the same setting. Always click Start of Broken
Waveform first.
9. Select Ch 2 in the Channel field.
10. Click Set to 0 . This will reset the value of TEK0015 Data Delay to 0 ps.
11. Repeat step 5 through step 8.
12. Click Update Cal Values .
13. Select Ch 1 in the Channel field.
14. Set Frequency to 10 GHz, and observe the oscilloscope screen. If a sine
waveform is not output normally, record the range as described in step 6 and
step 7.
15. Decrease Frequency in the Parameters for Step 0,4 field every 50 MHz from
10.000 GHz to 7.000 GHz using the up/down button or the front-panel rotary
knob. You can also enter the value directly using the keyboard.
16. If the waveform starts to break at some point, click Start of Broken
Waveform . Click End of Broken Waveform right before the next waveform
is output normally (the last position where the waveform is broken in that
range).
17. Continue the measurement to 7 GHz.
18. Select Ch 2 in the Channel field.
19. Reset the value of Frequency to 10 GHz.
20. Repeat step 14 through step 16.
21. Click Update Cal Values .
22. Click Save to EEPROM .
23. Click Close . The Data Timing Calibration window closes.
