LAB TESTING

Test Bench Overview

Specialized test benches are used to determine the AC

characteristics of the Device−Under−Test (DUT). A typical

test bench setup for a differential device is shown in

Figure 1.

Test Initialization

• The test cables are connected from the pulse generator to

the appropriate DUT test board input connectors.

• The test cables are connected from the DUT test board

output connectors to the appropriate digital sampling

oscilloscope input connectors.

• The power supply cables are connected to the DUT test

board power supply connectors.

• The airflow regulator is set to 500 lfpm and the desired

DUT ambient air temperature. The DUT is in this

environment for a minimum of 3 minutes before testing

begins. Data sheet specifications are typically given for

−40

°C, 25°C, and 85°C.
