The Keithley 2015/E is a six-and-a-half-digit audio analysis digital multimeter. It combines audio band quality measurement and analysis with a multi-purpose digital multimeter function set, enabling various measurements in a compact half-rack instrument. Its features are as follows:
Powerful audio measurement capabilities: It can measure total harmonic distortion (THD) in the 20Hz to 20kHz audio band range, and can also calculate total harmonic distortion + noise (THD+N) and signal-to-noise and distortion ratio (SINAD), meeting the high-precision measurement requirements related to audio.
Dual-output audio band sine wave signal source: One output generates a stimulus signal, and the second output is opposite to the first output, which can simplify the testing of differential input circuits, achieve common-mode or noise cancellation performance, and facilitate the testing of differential input circuits.
Fast frequency scanning: It can quickly calibrate audio band circuits in production test systems, helping to improve production test efficiency, shorten test time, and reduce costs.
Excellent harmonic measurement capabilities: In distortion measurement, it can include up to 64 harmonic amplitudes. By programming the number of harmonics to be included in the calculation, the accuracy, speed, and complexity of specific tests can be optimized.
Rich digital multimeter functions: It has 13 digital multimeter functions (six-and-a-half-digit), covering various measurements such as voltage, resistance, current, and frequency, meeting the measurement needs of various basic electrical parameters. When configuring test settings, it can minimize the cost of additional equipment.
Multiple filter configurations: It has 5 standard audio shaping filters, which can filter out the electromechanical noise in the production workshop or simulate other types of system transmission characteristics, providing a more accurate environment for audio measurement.
Convenient communication interfaces: It is equipped with GPIB and RS - 232 interfaces, which are convenient for connecting and communicating with other devices, facilitating the realization of automated testing and data transmission.
