Audio Analyzer Accessories
Expand the Functionality of Your Analyzer
AP offers dedicated hardware accessories and internal modules to help expand your analyzer functionality.
APx1701 Transducer Test Interface
The APx1701 is designed for electro-acoustic testing and drives loudspeakers and headphones with dedicated power amplifiers, enables impedance measurements, and provides power to measurement microphones and microphones under test.
SWR-2755 B Series Switcher
The SWR-2755B series bring significantly lower crosstalk (18 dB better in an unbalanced 600 Ω load; 10 dB better in a balanced 600 Ω load), a universal power supply that automatically adjusts to all line voltages, a convenient rear-panel ground lug and full EMC and safety regulatory compliance.
AUX-0025 / 0040 / 0100 Switching Amplifier Measurement Filters
Providing signal preconditioning for measurement accuracy in Class-D amplifier test, this switching amplifier is designed to be inserted between the device under test (DUT) and an analyzer input, to reduce out-of-band switching signal components before measurement.
PDM Line Driver
For enabling system set-up flexibility in PDM MEMS testing.
GRAS Measurement Microphones & Acoustic Test Accessories
Developed for R&D engineers and production technicians who need the highest possible performance, a broad range of digital I/O options and fast, intuitive software.
