Adjustment Procedures
13. Use the sampling oscilloscope to measure R1-Rise to C1-Rise Delay .
R1 is the intermediate value between High Level and Low Level values
measured in step 5, and C1 is the intermediate value between High Level and
Low Level values measured in step 7.
14. Enter the delay value in pico second to the Cal. Value (Skew) entry fi eld in
the Interleave Calibration window, and then click Set .
15. Use the up/down 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,
8.0 GHz, 7.0 GHz, 6.0 GHz, and repeat the measurements described in step 8
through step 15. The target value varies depending on the selected Sampling
Rate.
a. Select 11.0 GHz in the Sampling Rate fi eld, and then repeat the
measurement. The target value is 45.5 ps ± 2 ps.
b. Select 10.0 GHz in the Sampling Rate fi eld, and then repeat the
measurement. The target value is 50.0 ps ± 2 ps.
c. Select 9.0 GHz in the Sampling Rate fi eld, and then repeat the
measurement. The target value is 55.6 ps ± 2 ps.
d. Select 8.0 GHz in the Sampling Rate fi eld, and then repeat the
measurement. The target value is 62.5 ps ± 2 ps.
e. Select 7.0 GHz in the Sampling Rate fi eld, and then repeat the
measurement. The target value is 71.4 ps ± 2 ps.
f. Select 6.0 GHz in the Sampling Rate fi eld, 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.
