Measuring Bit Error
The setting procedure of the error detection conditions is as follows:
1. When changing the bit rate and pattern of the PPG and applying the
changing settings to the ED touch the Tracking button and set to
[On].
When setting to [On], go to the step 6.
When setting to [Off], go to the step 2.
2. Touch the Bit Rate button and select the standard.
Set the same standard of the PPG.
3. Touch the Test Pattern button and select the pattern.
Set the same pattern of the PPG.
4. Set Logic to [POS] or [NEG].
5. Touch the Data Input Condition button.
6. Select the connector receiving the signal from the followings:
[Differential 50 Ohm]: Data In and Data In connectors
[Electrical Single-Ended Data]: Data In connector
[Electrical Single-Ended XData]: Data In connector
7. Touch the External ATT test box.
8. When inserting the fixed attenuator to the Data In and Data In
connectors, enter the attenuation (dB). When not inserting the
attenuator, enter 0.
9. Touch the Threshold text box.
10. Enter the threshold voltage.
When Test Pattern is set to Programmable Pattern, follow the procedure
below.
11. Touch the Programmable Pattern button and open the file dialog box.
12. Select the same file as that of the Programmable Pattern of the PPG.
13. Touch the Frame Position text box.
14. Enter the frame head position.
