Model 100: To Connect ASU

The Agilent E5288A Atto Sense and Switch Unit (ASU) will add the 1 pA range to the

high resolution SMU (HRSMU) when it is connected between the HRSMU and the device

under test (DUT). And the ASU provides the input selection function when instruments are

connected to the SMU input and the AUX input.

NOTE For the installation of the ASU and the connection to the DUT interface, contact your

favorite prober vender. The prober vender will be able to provide the DUT interface that

can be connected directly to the ASU output. Dimensions of the ASU are 132 mm (W)

50 mm (D) × 88.5 mm (H) excluding the connectors.

To install 16495K Fix the Agilent 16495K Plate to the shielding box or something that will cover the

manipulators or the probe card (DUT interface). See Agilent 16495 Installation Guide. The

16495K is the plate used to block the light from the cable hole.

To install ASU 1. Fix the ASU in the shielding box. The ASU must be fixed to the best position for

accessing cables that come from the DUT interface and the instruments. The Agilent

N1254A-108 Magnetic Stand will be useful for fixing the ASU.

2. Pass the measurement cables (Agilent 16493M, 16494A, BNC cable, and so on)

through the cable hole of the 16495K. They will be connected between the ASU and

the instruments

3. Connect the 16493M cable to the ASU D-sub connector.

Connect the 16494A triaxial cable to the ASU Force terminal.

Connect the BNC cable to the ASU AUX In terminal. For the instrument without the

four-terminal-pairs inputs, open the CMU-pot terminal or cover it by using the BNC

open cap.

4. Adjust the cable length in the shielding box, and catch in the cables by using the

16495K.

5. Connect the cable extended from the DUT interface to the ASU output terminal. If you

do not make the Kelvin connection, open the Sense terminal or cover it by using the

triaxial open cap.
