To prevent problems, connect the 3110 series and the equipment under test using the
Shortest Twisted Wire possible to keep the voltage caused by inductance between the
Minimum operating Voltage and the maximum input voltage range or set a low slew rate.
If the high-speed response operation is not required, decrease the slew rate setting.
In such settings, the value of DI /DT will be decreased, accordingly the generated voltage
Will be Reduced even the inductance of load wiring can not be reduced.
In the case of DC operation also, the phase delay of the current may cause instability in
The 3110 Series Control inducing oscillation. In this case also, connect the 3110 Series
And the equipment under test using the shortest twisted wire possible.
If only DC operation is required, a capacitor and a resistor may be connected to the load
Input Terminal as shown in Fig. 2-4 to alleviate oscillation. In this case, use the capacitor
Within its Allowable ripple current.
Keep the wire short
