The metal noise shield surrounds the test circuit and should be connected to SMU 
LO (as shown in 

Figure 3-10

), and can also be connected to the chassis ground 

screw on the rear panel of the Series 2600.

Figure 3-10

Noise shield

Safety shield

A safety shield must be used whenever hazardous voltages (

>

30Vrms, 42Vpeak) 

will be present in the test circuit. The safety shield can be metallic or nonmetallic, 
and must completely surround the DUT test circuit. A metal safety must be 
connected to a known safety earth ground and chassis ground (See “

Test fixture

”  

later in this section for important safety information on the use of a metal or non-
metallic enclosure.).

Model 2601/2602 safety shield

The maximum output voltage for a Model 2601/2602 channel is 40V, which is 
considered a non-hazardous level. However, using two or more Model 2601/2602 
voltage sources in a series configuration can cause test circuit voltage to exceed 
42V. For example, the SMUs of two Model 2601/2602 instruments can be 
connected in series to apply 80V to a DUT (see 

Figure 3-11

). 

The connections for the test configuration in 

Figure 3-11

 are shown in 

Figure 3-

12

Use #18AWG wire or larger for connections to safety earth ground and chas-

sis. 

NOTE

Floating an SMU may also cause test circuit 
voltage to exceed 42V (see 

Floating an SMU

”  

later in this section).
