This Analyzer can meet the above challenges at frequencies below 45Hz.

These two models provide precise control of the waveform generation and measurement system for optimal operation at low frequencies.

For this example, the equipment under test will require an ac input at 230Vrms and 16.6Hz.

Real power, apparent power, and power factor will be accurately measured using the high resolution current measurement range.

Generating low frequency waveforms with ac sources can present testing challenges due to output power derating and programming inaccuracies, depending on the regulation technique used.

If the ac source has measurement capability, control of the measurement sample period is necessary to capture sufficient cycles of the output waveform to ensure measurement accuracy.
