PPA55xx Series – Extended Harmonics Mode

webteam — Fri, 01 Jul 2011 12:00:18 +0000

In relation to aircraft applications, a standard called DO160 defines the minimum test conditions and corresponding test procedures for airborne equipment.

Within a POWER section of the standard, the measurement of voltage and current harmonics is defined and the requirements of this measurement are significantly more demanding than harmonic tests typically required in power electronic analysis.

Harmonics of a fundamental power signal in the range 400Hz to 800Hz are required over a frequency range that extends to 150kHz. Over this frequency range, harmonics of the fundamental must be measured for any harmonic that is over 0.25% of the fundamental (or 5mA in current if that is higher).

In response to this need, N4L have introduced new firmware for the PPA55xx series that meet the requirements of this exacting harmonic measurement application.

Spectrum mode added to the PPA55xx Series

stuart.chappell — Thu, 05 May 2011 10:58:14 +0000

Providing a solution to applications that require discrete harmonics and also interharmonics or non harmonic frequency domain information, the latest firmware version of the PPA5500 series power analyzer includes an FFT based spectrum mode.
