SETUP FOR MEASUREMENTS
This section explains how to connect and setup the
1. Set E3620A to output 3.3V and then turn off
2. Configure Agilent BERT stack:
E3620A. Connect E3620A’s positive lead to GND
post and negative lead to VEE post. Note that the
board uses a negative supply; ensure that the
power supply polarity is correct.
