80A09 26 GHz ESD Protection Device Instructions
BNC T connector.
Two BNC cables (example: Tektronix part number 012-0076-xx, 20 inch
BNC cable).
Two BNC to Banana plug adapters.
Precautions while
performing the test
This test checks the 80A09 leakage and clamping thresholds. Use caution when
operating the Source Measure Unit (SMU) in this test setup. Even though the
80A09 protects the 80E04 from reasonable overvoltages, use care to avoid
damaging the 80A09. Follow these precautions:
Always disconnect the 80A09 from the sampling module input for this test.
Always set SMU test limits as speci
fi
ed.
Always disable the SMU output before connecting or disconnecting the SMU
supply from the test setup.
Set the SMU at zero volts before enabling the output.
Procedure
CAUTION.
Follow ESD handling guidlelines when connecting cables to the
80A09. (See page 1, Best practices to prevent ESD.)
1.
If connected, remove the cable from the 80A09.
2.
Remove the 80A09 from the 80E04 module input.
CAUTION.
Do not perform this test with the 80A09 connected to the 80E04. Doing
so can damage the 80E04 module input.
Do not connect a ground or 50
Ω
terminator to the 80A09.
3.
Con
fi
gure the SMU before connecting to the 80A09:
Set the SMU at zero volts.
Disable the SMU supply output.
4.
Connect the adapters and cables as shown in the following diagram.
