SETUP FOR MEASUREMENTS
This section explains how to connect and setup the
1. Set E3620A to output 5V and then turn off E3620A.
2. Configure Agilent BERT stack:
3. Connect 70843V’s trigger output to 86100A’s trigger
4. Short J1; open J3 on SY88702 evaluation board
5. Connect DIN and /DIN on SY88702 evaluation board
Connect E3620A’s positive lead to GND post and
negative lead to V
a negative supply; ensure that the power supply
polarity is correct.
a) Set the 83752A synthesized sweeper to 622MHz

the power supply leads have been connected
backwards. Be careful of this!
a) Verify a trigger signal is present by checking that
