Note: Before performing these automated adjustments:
• Ensure that the Device Under Test (DUT) and all test equipment have been turned on
at lease 45 minutes. Shorter warm-up times may result in improper adjustment.
• Ensure that all GPIB connections are securely made between the test equipment, the
DUT, and the PC.
