The Instrument Control Software (ICS) offers a soft front panel interface for
operation from a PC running Windows VistaTM, Windows XPTM, or Windows
2000TM. The following functions are available through this software:
· Steady state output control (all parameters).
· Create, run, save and print transient programs.
· Generate and save harmonic waveforms.
· Generate and save arbitrary waveforms.
· Measure and log standard measurements.
· Capture and display Voltage and Current waveforms.

Transient Generation
To simulate complex current events, the CS Series offers a list of transient steps.
These steps can be programmed from the front panel or downloaded over the
interface using the software supplied. The ICS allows libraries of commonly
used sequences to be created on disk for quick recall. Once downloaded, the
transient program can be executed from the PC or from the front panel.
AC current transient generation allows the effect of rapid changes in current,
