10. The D3186 Pulse Pattern Generator must use its own reference clock. Set the
following data signal parameters on the pattern generator:
H
AC coupled
H
DATA output mode
–2 V
H
Amplitude 0.700
V
H
Offset
–1.00 V
H
PRBS23 pattern
H
NRZ data format
H
Balanced duty cycle (crossing set to the default 50% level)
H
Data rate to 2.48832 Gb/s (the data rate will be changed, depending on
each specific data rate to be tested later in the procedure)
11. Set the variable optical attenuator for minimum attenuation.
12. Allow the TDS8000 or CSA8000 and its modules to warm up for at least 20
minutes in an environment that has had less than 1
°
C variation throughout
the warm-up cycle.
13. Press the DEFAULT SETUP button on the TDS8000 or CSA8000 instru-
ment.
14. Press the SELECT ON/OFF button on the 80C0X Optical Sampling Module
so that the adjacent indicator lights. This turns on Channel 1 (C1) on the
80C0X-CR Optical Sampling Module.
15. Press the SELECT ON/OFF button on the 80E02 Sampling Module so that
the adjacent indicator lights. This turns on Channel 3 (C3), which displays
the CLOCK signal.
16. From the Setup Menu, select the Trig Setup dialog box. Make the following
changes:
a. Select External Direct as the Trigger Source.
b. In the Level section, click the Set to 50% button.
c.
Select positive edge for the Slope.
17. Select the Meas Setup dialog box. Make the following changes:
a. Select Meas 1 in the scroll-down control box.
b. Click the Select Meas button.
