Once you have connected your external AC source to the AT3600/AT5600 tester via the AC Interface, you
will have to configure the test program in the PC Editor.
There are three steps to this configuration:
3.1 Configuration of the external AC source
3.2 Selection of the sense method
3.3 Selection of the external AC source in the PC Editor Program Options

3.1.1 For A Step-Up Transformer
This source type is a transformer that may be used to boost the voltage or current that is produced by the
internal high-power generator of the AT3600/AT5600.
For example, a transformer could be used to either step up the AT3600/AT5600’s voltage or provide a higher
current at lower voltages.
The benefits are that:
The AT3600/AT5600 will trim the output voltage during testing, so that the voltage across the test piece will
always be at the programmed level, even if the gain of the source drifts or the impedances of the test parts
are different.
The AT3600/AT5600 will ramp the test voltage up and down in a controlled manner, minimizing settling time
and optimising test speed.
NOTE: Using a transformer in this way cannot boost the power available. This is limited to 25 Watts
Open the PC Editor and from the ‘Setup’ menu choose ‘External Sources’.
Click on ‘New’ to configure a new external source.
