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.
