Connecting the Agilent 83433A to a Bit-Error-Ratio Test Set

Connecting the Agilent 83433A to a 
Bit-Error-Ratio Test Set

The following procedure describes how to connect the lightwave transmitter 
to a bit-error-ratio test set (BERT). The following equipment is used:

• Agilent 83433A lightwave transmitter
• Lightwave receiver or Agilent 83434A
• Bit error ratio tester or Agilent 71612B error performance analyzer
• Optical attenuator
