$5.240
The Keithley 2015-P combines precision multimeter functions with high-performance audio analysis, delivering both 6½-digit resolution and comprehensive THD/SINAD capabilities. Featuring built-in harmonic analysis, a programmable sine wave generator, and full-frequency domain testing, it’s the ideal choice for engineers working with audio, telecom, or precision analog systems.
Keithley 2015-P – 6.5 Digit Audio Analyzing Multimeter with GPIB and RS-232 Interfaces.
Engineered for professionals requiring accurate electrical test and audio testing in a single instrument, the Keithley 2015-P Audio Analyzing Multimeter offers a powerful blend of 6.5-digit DMM performance with integrated Total Harmonic Distortion (THD), SINAD, and audio signal analysis. Equipped with GPIB and RS-232 interfaces, it supports automated testing environments and bench setups alike.
A standout feature is its dual-output sine wave source with frequency sweeps and low-distortion performance (–64dB THD). This makes the 2015-P perfect for audio equipment manufacturers, R&D labs, and automated production test stations.
