80A09 26 GHz ESD Protection Device Instructions
NOTE.
Make sure to connect the ground (GND ) side of each BNC to Banana plug
adapter to the LO connectors of the SMU.
5.
Use the following guidelines while using the SMU with the 80A09:
Do not exceed the test voltage value.
Once tested, reduce the voltage to zero volts before changing SMU
settings.
Do not disconnect or reconnect any test cables until you reduce the output
to zero.
6.
Set the SMU to output
+2.0 VDC
. Verify that the measured current is less
than
+100
μ
A
.
7.
Set the SMU to output
–2.0 VDC
. Verify that the measured current is less
than
–100
μ
A
.
8.
Set the SMU to source
+65 mA
, with the overvoltage limit set to
+3.5 V
.
Verify that the measured voltage is
≤
3.42 VDC
.
9.
Set the SMU to sink
–65 mA
, with the overvoltage limit set to
–3.5 V
. Verify
that the measured voltage is
≥
–3.42 VDC
.
10.
Set the SMU output to
zero
volts, disable the SMU output, and disconnect the
SMA to BNC adapter from the 80A09.
CAUTION.
If any of the checks are outside the stated limits, the 80A09 device
can no longer provide ESD protection. Do not use a defective 80A09 with an
80E04. Contact Tektronix Customer Support to order a replacement 80A09 ESD
Protection Device.
11.
Repeat all of these steps to test other 80A09 devices.
