1Introducing the Agilent 85225F Performance Modeling System

The CV Subsystem

The Agilent 4284A precision LCR meter provides a wide 20 Hz to 1 MHz test frequency range and superior test- signal performance, allowing CV testing to the most commonly- used test standards, such as IEC/MIL, and under conditions that simulate the intended application.

Optionally, the system can be configured with the Agilent E5250A low leakage switch mainframe. The Agilent E5250A is used for precise parametric test. It improves measurement efficiency by eliminating the need to manually change the probe positions on a manual probe station. The E5250A is used to route signals from the DC and CV subsystems to the probe card cable, and on to the probe card and probe station.

Component Integration

System component integration is performed at the Agilent Technologies factory. The individual components are placed into the rack, and the required cabling is connected between the instruments.

After factory integration, the system is tested to verify functional performance.
