Analog system 1 kHz THD+N, 20 kHz BW ≤­ –112 dB
AP’s flagship analyzer, the 2700 Series is designed for audio
engineers who need the highest performance, lowest distortion
and greatest flexibility possible in their audio analyzer.
The 2700 Series has the best performance of any audio
analyzer in the world: its high-precision analog audio design is
markedly superior to the best digital implementations in several
key areas, especially residual noise and distortion, and high-
bandwidth.
The unparalleled accuracy of a dedicated hardware instrument
Fast instrument operation and powerful analysis under
sophisticated control software
Programmatic control for high-speed automation
Serial digital interface testing
True dual domain instrument for highest performance
192 kHz digital input and output capabilities
500 kHz analog / 100 kHz digital measurement bandwidth
Vanishingly low residual noise and THD+N
Generates and analyzes a broad palette of stimulus signals such as
MLS, white and pink noise and other special purpose waveforms
