The rms current limit is set to 10 A. If more current than the
programmed limit is drawn, the output voltage amplitude is reduced to
keep the rms current within the specified limit. Press [Shift] [Current]
and ▼ to access CURR:PEAK, which lets you set the peak current limit
on the ac source. The peak current limit circuit on the ac source acts
instantly and clips the output voltage to maintain the programmed peak
limit.
NOTE: The rms current limit circuit is slower than the peak current limit
circuit and, depending on the setting of the peak current limit and the
load on the output, your ac source may generate momentary peak
currents that can well exceed the rms current limit.
The output generates a square wave. The peak-to-peak amplitude of the
square wave is less than that of a sine wave when it is programmed to
the same rms voltage amplitude.
