Adjustment Procedures
d.
Measure
R1 to C1 Delay
using the Measurement function of the sampling
oscilloscope. Select the following parameters in the Inter-Channel Skew
Calibration window:
Sampling Rate: 6.0 GHz
Ch 2 Phase: 0 °
e.
If the delay value measured in step d is outside ±83 ps range, change
the Sampling Rate to 12.0 GHz and then return the setting to 6.0 GHz.
Measure
R1 to C1 Delay
again. Repeat this measurement until the R1
to C1 Delay value is within the ±83 ps range.
f.
Change the parameters as follows in the Inter-Channel Skew Calibration
window:
Sampling Rate: 6.0 GHz
Ch 2 Phase: +180 °
g.
Enter the measurement values of
R1 to C1 Delay
for each setting to the
fi
rst place after the decimal point while changing the Ch 2 Phase settings
from +180 degrees to -180 degrees using either the mouse or the Tab key.
Adjust the horizontal position of the sampling oscilloscope as necessary
so that the rising edge of the waveform is displayed at the center of the
screen.
h.
After you complete all the measurements for
Sampling Rate: 6.0 GHz
,
click
Calc (Delay to Phase)
. This will display the calculated phase values
in the Ch1– Ch2 Phase (degree)
fi
eld.
i.
Select
Sampling Rate: 12.0 GHz
.
j.
Disconnect the SMA cable from the Ch 2 Analog (+) Output, and then
connect it to the Ch 1 Analog (+) Output.
k.
Adjust the horizontal position of the sampling oscilloscope so that the
rising edge of the arbitrary waveform generator Ch 1 Analog (+) Output
waveform is visible near the center of the oscilloscope screen, and then
select File Menu > Save Waveform... to save the waveform data to R1.
l.
Disconnect the SMA cable from the Ch 1 Analog (+) Output, and then
connect it to the Ch 2 Analog (+) Output.
m.
Change the parameters as follows in the Inter-Channel Skew Calibration
window:
Sampling Rate: 12.0 GHz
Ch 2 Phase: +180 degree
n.
Enter the measurement values of
R1 to C1 Delay
for each setting to the
fi
rst place after the decimal point while changing the Ch 2 Phase settings
in the order from +180 degrees to -180 degrees using either the mouse or
the Tab key. Adjust the horizontal position of the sampling oscilloscope
