2.Connect the Generator to the Analyzer.

Connect the generator and analyzer as shown below. The generator CLOCK output connects to the analyzer CLOCK input. The generator DATA output connects to the analyzer DATA input. The rear panel THRESHOLD output on the Rx connects to the Receiver NOT-DATAinput on the front panel. Terminate the generator NOT_CLOCK and NOT_DATA signals with the 50Ω terminators located on the front panel of the generator.

Note: Do not mix up the clock, not_clock, data, and not_data signals or tutorial results will be different.

3.Setup Generator for PRBS-23 Mode.

Locate the controls in the OUTPUT box of the Generator. Setup the Generator clock and data outputs as follows:

Set this parameter

…to this value

…using this procedure.

 

 

 

DATA amplitude.

1 volts

Press the DATA key. The LED within the switch

 

 

should be lit.

 

 

Press AMPLITUDE up/down keys until data

 

 

amplitude is set to 2.00V.

 

 

 

DATA baseline offset

-0.5 volt

Press BASELINE OFFSET up/down keys until

 

 

data baseline offset is set to -0.50V.

 

 

 

CLOCK amplitude

1 volts

Press CLOCK. (the LED within switch should be

 

 

lit).

 

 

Press AMPLITUDE up/down keys until clock

 

 

amplitude is set to 2.00V.

 

 

 

CLOCK baseline

-0.5 volt

Press BASELINE OFFSET up/down keys until

offset

 

clock baseline OFFSET is set to -0.50V.
