AP 2722

The 2700 Series offers an array of powerful, time-saving analysis tools to speed your testing procedures.

Multitone
Multitone testing techniques can provide response, distortion, noise, crosstalk and phase measurements—all from a single sub-second acquisition. You can address a wide variety of high-speed testing applications by choosing a standard stimulus waveform, or by making your own using the multitone creation utility. In addition to great speed, multitone analysis brings other advantages: a stimulus signal, for example, that is a rich mix of frequencies, levels and phase relationships that more closely resembles program material than conventional single stimulus tones; and the unique ability to measure noise or very low distortion products in the presence of signal.

Fast RMS Detector
The DSP-implemented Fast RMS Detector speeds sine wave sweeps by making measurements in as little as one cycle of the sine wave. This can provide an improvement in testing speed of an order of magnitude compared to normal RMS detector techniques

Harmonic Distortion Analyzer
An FFT-implemented dual-channel Harmonic Distortion Analyzer can simultaneously measure the individual amplitudes of a fundamental frequency and up to four harmonic products, selectable from the 2nd to the 15th harmonic. Sweeps using this analysis tool can rapidly characterize frequency or amplitude dependent distortion mechanisms.

Advanced settling
A sophisticated data settling algorithm enables you to optimize the inherent trade-off between testing speed and measurement accuracy in sweep tests. Individual settling parameters are stored for every measurement available in the instrument.

MLS (Maximum Length Sequence)
Quasi-anechoic measurements of transducers and acoustic spaces can be performed using MLS (Maximum Length Sequence) signals and analysis to produce impulse, frequency and phase response graphs in less than one second.

Filter Creation Utility
Make noise measurements to virtually any international standard using our extensive collection of weighting and band-limiting filters. Use optional Audio Precision hardware filters (for the Analog Analyzer) or Audio Precision software filters (for the DSP Audio Analyzer); or make your own user-downloadable software filters using the Filter Creation Utility.

“Manual device characterization takes far too long a time. Automated AP2700 test systems drastically improved our test coverage and repeatability.”
