Setting up Measurement Environment

This chapter explains how to connect your instruments to Agilent E5250A input, and how to connect the E5250A output to your wafer prober or test fixture.

You can connect the E5250A output (E5252A or E5255A) to your prober or fixture in the following three ways:

Via the available connector plates.

(For E5255A only) Directly using Agilent 16494E coaxial cable.

Via connectors that you mount directly on your own connector plate or test fixture.

This chapter explains how to do this in the following sections:

“Connector Plates” introduces connector plates available for the plug-in card. For installing the connector plates on your shielding box for prober or fixture, refer to Agilent 16495 Installation Guide.

“Connecting 8-Channel Shielded Coaxial Cable” explains how to use the 16494E coaxial cable, which is used to directly connect the E5255A output to the DUT, DUT socket, or any fixture you want without using a connector plate.

“Mounting Connectors Directly” describes connector hole dimensions for mounting connectors directly on your own connector plate or test fixture, and describes the information to connecting the connectors to prober, socket or DUT.

“Connecting the E5250A Input” explains how to connect instruments to the E5250A input.

“Connecting the E5250A Output” describes the information to connect the plug-in card output to a connector plate, connectors on your own shielding box and so on.

“Measurement Cable Length” is a reference for deciding total cable length at your site by calculating the total guard capacitance according to the cable length from instrument to Device Under Test (DUT).
