Higher pulse voltage can be output by connecting two (and only two) Series 2600B instrument
channels in series. When combining two SMU channels, make sure both SMUs have the same model
number.
The following figure illustrates a Model 2612B configured with the two channels connected in series to
output up to 400 V (200 V per channel).
Whenever hazardous voltage (>30 V RMS, 42 V peak) will be output, a safety shield must completely
surround the DUT test circuit. When using a metal safety shield, it must be connected to a known
protective earth (safety ground) and chassis ground.
Figure 26: Stacking channels for higher voltage
(1) Model 2612B Ch A: SMU maximum pulse voltage: +200 V
(2) Model 2612B Ch B: SMU maximum pulse voltage: -200 V
(3) Series SMU maximum pulse voltage (as shown): 400 V

Combining channels in parallel to output higher current
Higher pulse current can be output by connecting two (and only two) Series 2600B instrument
channels in parallel. When combining two SMU channels, make sure both SMUs have the same
model number.
