Adjustment Procedures
13. Use the samplin
g oscilloscope to measure R1-Rise to C1-Rise Delay.
R1 is the intermediate value between High Level and Low Level values
measured in st
ep 5, and C1 is the intermediate value between High Le vel and
Low Level values measured i n step 7.
14. Enter the de
lay value in pico second to the Cal. Va lue (Skew) entry field in
the Interleave Calibration window, and then click Set.
15. Use the up/d
own button or the front-panel rotary knob to adjust the Ch2
Clock Phase value so that the R1-Rise to C1-Rise Delay value on the
sampling oscilloscope is 41.7 ps ± 2 ps. The target value is displayed on the
middle right of the Interleave Calibration window.
16. In the same way, select the Sampling Rate 11.0 GHz, 10.0 GHz, 9.0 GHz,
8.0GHz,7.0GHz,6.0GHz,andrepeatthemeasurementsdescribedinstep8
through step 15. The target value varies depending on the selected Sampling
Rate.
a. Select 11.0 GHz in the Sampling Rate field, and then repeat the
measurement. The target value is 45.5 ps ± 2 ps.
b. Select 10.0 GHz in the Sampling Rate field, and then repeat the
measurement. The target value is 50.0 ps ± 2 ps.
c. Select 9.0 GHz in the Sampling Rate field, and then repeat the
measurement. The target value is 55.6 ps ± 2 ps.
d. Select 8.0 GHz in the Sampling Rate field, and then repeat the
measurement. The target value is 62.5 ps ± 2 ps.
e. Select 7.0 GHz in the Sampling Rate field, and then repeat the
measurement. The target value is 71.4 ps ± 2 ps.
f. Select 6.0 GHz in the Sampling Rate field, and then repeat the
measurement. The target value is 83.3 ps ± 2 ps.
17. Click Update Cal Values.
18. Click Save to EEPROM.
19. Click Close to close the Interleave Calibration window.
