二手ST4036 音频分析仪

ST4036 is a low-distortion stable amplitude oscillator designed to meet the needs of today’s audio test and measurement technology. Covering the frequency range from 10Hz to 100kHz , the ST4036 produces a very low distortion sinewave for measuring audio preamplifier and power harmonic distortion. With its outstanding flat response of 0.2dB, the ST4036 eliminate the of constantly monitoring the voltage level during the frequency response test. Exact frequency and amplitude setting is provided by means of a digital Frequency / Amplitude readout. ST4036 provides 30Vpp, selectable sinewave or squarewave. two push button attenuators calibrated in 20 dB steps, alongwith 20 dB vernier, provide a total of 60dB output voltage attenuation.
