<P>The Aim-TTi PL303-P offers remote control and read-back using analog,
RS232, USB, LAN (LXI) interfaces. They retain all of the capabilities of the New
PL Series when under manual control.</P>
<P>When working with any particular piece of equipment, engineers often require
a voltage source variable over only a narrow range. Set the voltage too high and
damage might occur, set it too low and the circuit may reset.</P>
<P>That‘s where the V-Span function of the Aim-TTi PL303-P comes in. It
allows the user to redefine the end-stop values of the voltage control to define
a specific voltage range.</P>
<P>An engineer is working on a circuit that will eventually operate from four
NiMh cells. They use V-Span to set a Vmax of 5.8V (to prevent over-voltage
damage) and a Vmin of 3.6V (to ensure that the circuit doesn‘t reset). They now
have a power supply which provides high resolution analog control over the exact
voltage range they need.</P></p>
