Figure 40: Models 2634B and 2636B SMU connections (Model 2635B similar)
The external voltage source can be a SMU of a second Series 2600B instrument or other instrument.
Keep in mind that if the combined outputs of the sources exceeds 42 V, then a safety shield will be
required for the DUT (see the following WARNINGS).
The maximum floating (common mode) voltage for a SMU is ±250 V. Exceeding this level may
cause damage to the instrument and create a shock hazard.
Using an external source to float a SMU could create a shock hazard in the test circuit. A
shock hazard exists whenever >42 V peak is present in the test circuit. Appropriately rated
cables or insulators must be provided for all connections to prevent access to live parts.
When >42 V is present, the test circuit must be insulated for the voltage used or surrounded
by a metal safety shield that is connected to a known protective earth (safety ground) and
chassis ground (see
Safety shield
(on page 2-63)).
DUT connection settings
Make sure to properly configure the Series 2600B sense mode for the specific DUT test connection
scheme. Use care to configure the output-off state to supplement safe operation of your test setup.
