(3) Procedure
1. Connect
the
Clk Out
connector and the
Trigger Clk In
connector
of the sampling oscilloscope using a coaxial cable.
2. Connect the coaxial terminator to the
ED1
Data
In
connector
and
PPG1
Data
Out
connector.
3. Attach a 20 dB fixed attenuator to the
PPG1 Data Out
connector.
(Refer to (a) in Figure 7.2.2-1.)
4. Connect the 20 dB fixed attenuator and
Ch A In
connector using
a coaxial cable.
