Output VA Capability

The output capability of each output phase is limited by VA (volts-amps) rather than power (watts). The amount of VA available to a load can be determined by examining figure 1-3, the output power curve. This curve rates the available VA versus output voltage. Full VA is available only at a full-scale voltage. Full current is available at voltages between 50% and 100% of the output voltage range. Appendix A documents the ac source’s specifications and supplemental characteristics.

NOTE: The load on the ac source may draw full VA at any power factor between 0 and 1, and may draw maximum current with a crest factor of 4 (3 for Agilent 6843A). If the load draws current in excess of the maximum rated rms or peak current, the voltage amplitude will be clipped to prevent excessive internal power dissipation.
