- Now you can move on to test Channel 2.
- After the report is saved and the browser window is closed, close the "plots" window to make the 4 plots that you saw go away. You should now see the signal again.
- Press the Run/Stop button to get the signal going again.
- Change the source to channel 2 by using the < | > arrow button located just to the left and above the level knob.
- Now you will be using the level knob to set the trigger level for the blue signal, or channel 2. Again just shoot for the positive side of the signal and verify the "trig" light is on
- Once this is done, go down to the window that you selected Reports on and press the Results option. ????Choose the config panel and hit the channel 2 button to add it to the list underneath, then choose "Apply All".
- Press the "ReCalc" button on the right of this window.
- This should start the entire process over again, once it's finished and now plots pop up, you can go back to the Reports window, and save the report modifying the save name accordingly.
- Now just remove the quick connect cables from the cmd data ports and move to data0, you can just go back to step 7, hit "ReCalc" and it will scan again, save the report and change back to channel 1.
- You only need to start all the way over when you change USB cables, after cmd, data0, data1, data2 and data3 is scanned and the reports are saved. You should also not have to turn off anything until the very end, you can unplug and plug in the new cables on the fly.
Update:
Better to do all measurements on Math1 = Ch1 - Ch2 to half the number of tests required. Press Clear → ReCalc for every new channel. Record the signal amplitude, eye height, and eye width @ 10e-12 BER as a comparison.
Results for the first batch of 44 DP cables can be found here.
