How do I stack channels to output higher voltage?
The maximum output voltage of a Model 2601 or 2602 channel is 40.4V, and the
maximum output voltage of a Model 2611 or 2612 channel is 202V. Higher volt-
age can be output by stacking (connecting in series) channels.
Stacking channels requires that all SMU channels (except one) float off earth
ground.
shows two Model 2602s configured with the four channels
connected in series to output up to 161.6V (40.4V per channel). Additional
channels can be added (stacked), but the LO terminal of any SMU channel in the
stack must never exceed 250V with respect to earth ground.
WARNING
The maximum floating (common mode) voltage for a SMU is
±250V. Exceeding this level may cause damage to the
instrument and create a shock hazard.
Whenever hazardous voltage (
>
30Vrms, 42Vpeak) 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 safety earth ground and chassis ground.
Reference
Refer to “Floating a SMU” in Section 3 of the Reference Manual for
details on floating SMU channels.
