Determining voltage and current characteristics for battery channel
NOTE
If possible, always use an oscilloscope to determine the timing and transient
characteristics of a DUT. The waveform information is very useful in setting up
the Model 2308, reducing setup time and achieving maximum performance and
productivity. The voltage and current characteristics of the DUT can be
determined with a 2-channel Oscilloscope as shown in
Figure 3-3
. Differential
oscilloscope inputs are required to prevent grounding the supply output leads.
NOTE
Figure 3-3
contains a simple circuit for determining the dynamic voltage and
current characteristics of the DUT.
