The PowerSight FAO High Frequency Analysis Option is a combination of hardware, firmware, and software that allows your PS4500 to measure high frequency power-line noise. Normal harmonics analysis ends at 3,000 Hz (50th harmonic of 60 Hz fundamental). The FAO allows viewing the frequency content all the way up to 100,000 Hz, essentially turning your PS4500 into a spectrum analyzer. The FAO filters out the lower harmonic frequencies to allow measuring less than a volt of high frequency riding on a 1000 Vrms waveform. It can also do current high frequency analysis when used with one of our HA1000 current probes.

The FAO is a unique and essential product for:

Customers have used the FAO in applications where high-frequency noise could affect sensitive electronics, or affect precise measurements, or interfere with specialized manufacturing processes, or disrupt communication signals. This includes sensitive bio-medical measurement equipment, military communication applications, and industrial control in manufacturing plants with high populations of adjustable speed drives.

Utility power is generally not the source of high-frequency noise. This is because high frequency tends to dissipate over distance. Therefore the long line lengths of power distribution cables attenuates high frequencies unless they are generated close to your entry.

To analyze the high-frequency content of voltage, connect two voltage leads into the Voltage Conditioning Box (included in FAO). To analyze high frequency content of current, plug an HA1000 current probe into a special adapter cable (included in FAO) that then plugs into your PowerSight PS4500 meter. Note: an HA1000 current probe is not included in the FAO option, it must be purchased separately.
