(3) Procedure
1. Connect coaxial terminators to the PPG1 Data Out and ED1
Data In connectors. (Refer to Figure 9.2.4-1.)
2. Connect the PPG1 Data Out and ED1 Data In connectors using
a coaxial cable.
3. Touch [PPG/ED Ch1] and set [PPG] as follows:
Amplitude: 0.8 V
Bit Rate:
Variable, 11320000 kbit/s (Without the Option 092)
Variable, 12500000 kbit/s (With the Option 092)
Data/XData Out: On
Error Addition:
Off
Reference Clock: Internal
Offset: 0
ppm
Test Pattern: PRBS 2^31–1, Pos
4. Set [ED] as follows:
Data Input condition: Single-Ended Data
Gating Cycle:
Single
Gating Period: 10 s
Test Pattern: PRBS 2^31–1, Pos
Threshold: 0 mV
5. Touch [Start] at Measure.
6. After measurement, confirm that the error count of the ED
Result is 0.
7. Change Test Pattern for [PPG] and [ED] in succession to [PRBS
2^7–1], [PRBS 2^9–1], [PRBS 2^15–1], and [PRBS 2^23–1], and
repeat steps 5 to 7 each time.
8. Connect coaxial terminators to the PPG1 Data Out and ED1
Data In connectors. (Refer to Figure 9.2.4-2.)
9. Connect the PPG1
Data Out and ED1 Data In connectors
using a coaxial cable.
10. Set [ED] at Data Input condition to [Electrical Single-Ended
XData] at Data Input condition.
11. Repeat steps 3 to 7.
