The Data In 1, Data In 2 and Aux Clk In of M8061A have to be connected to Aux
Data Out, Data Out and Aux Clk Out ports of the J-BERT N4903B, respectively. The
connections should be made using the matched cable kit with the part number
M8061-61601. The Data Output has to be connected to the device under test.
The following example illustrates how to emulate transmitter de-emphasis up to
28.4 Gb/s with M8061A and J-BERT N4903B.
Setting up External Instrument(s) - Procedure
This section describes how to use the External Instrument(s) menu to enable
external instruments connected to the J-BERT N4903B.
N O T E
Before continuing to next step, make sure that the physical connection among the
Serial BERT and the external instruments are properly done and then turn them on.
Also ensure that you have properly installed the external instruments. For a
complete list of external instruments and their installation, refer to the section “
Installing External Instrument(s) - Concepts ” on page 538.
