There are one or more sections used during calibration of the Signal Generator gain. The number of sections has to
be equal the number of current ranges on the power device. The cell should be selected to produce a mid-range
voltage for the power device. Normally, the LPI is selected to have a similar voltage range to the power device.
Make sure the voltage produced is within the capability of both the power device and the LPI. Ohm’s law, V=IR,
dictates the voltage that will be produced for a given IApplied. The power, Power=IR
2
, dissipated in the calibration
cell should be kept low – below 80 W – to prevent any thermal impact. The example below depicts the information
for a BP4610 power supply from NF Corporation which has a single 10 A current range. Each of the keys for this
section will be discussed below.
