c.
Select Eye Pattern/Optical>Average Optical Power as the measurement
for C1. (Be sure Main C1 is selected as the Source.)
18. Select the Vert Setup dialog box and make the following changes:
a. Select C1 for Waveform.
b. Set the Wavelength to match the wavelength of the laser transmitter.
19. Select the Wfm Database Setup dialog box.
a. In the Database1 section, select Main C3 as the Source.
b. Check On for Database1.
20. Select the Meas Setup dialog box and make the following changes:
a. Select Main C3 as the Source.
b. Select Meas 2 in the scroll-down control box.
c.
Check the Use Wfm Database selection.
Follow this procedure to make the clock recovery optical sensitivity range and
recovered clock timing jitter checks:
1. In the Trig Setup dialog box, select the clock recovery rate for C1 that you
want to test (see Table 4–10).
NOTE
. Leave External Direct selected as the Trigger Source, even though you are
selecting a rate other than None. In this preliminary setup, the clock recovery
circuitry is enabled for the 80C0X-CR Optical Sampling Module, but the
TDS8000 or CSA8000 instrument timebase receives its trigger events from the
TRIGGER DIRECT input signal and not the actual recovered clock.
2. Set the data rate of the D3186 Pulse Pattern Generator to the rate setting for
the clock recovery rate that you selected in step 1 (see Table 4–10).
3. Adjust the Horizontal SCALE control on the front panel of the TDS8000 or
CSA8000 instrument to the setting listed in the table for the clock recovery
rate that you selected in step 1 (see Table 4–10).
