Four-wire connection for narrow pulse (<= 50 us)
Figure 2 shows the connection for 4-wire connections for narrow pulse (<= 50 us). For this configuration,
select the items shown in Table 1.
Note the following points for this connection:
•
The low inductance cable does not have Guard, and is limited to low current measurement.
Guard connection is required for low current measurement (~ 10 nA or less measurement.)
•
Do not connect the outer shield or Low Force to the chassis/frame ground of the DUT when
M9603A is grounded

In the case of
Low force = floating
If you perform grounded measurement,
attach the short bar.
Or if you perform floating measurement,
remove the short bar.
