Keysight / Agilent 8903A Overview
The 8903A Audio Analyzer provides automatic measurements of distortion, SINAD, signal-to-noise, frequency and many other parameters over a frequency range of 20Hz to 110kHz. To make these measurements easier the 8903A contains an internal low distortion (<0.003%) oscillator. Distortion is measured down to <0.003%. Additionally 3 filters, 400Hz hi pass, 30kHz and 80kHz low pass are provided to aid in removing unwanted signals. Input voltages can be measured from 300.0 V to 0.3 mV with a true RMS detector. SINAD is measured over a range of 0 to 99.99 dB with 0.01 dB resolution. An internal frequency counter will measure frequencies from 20Hz to 150kHz. Signal-to-Noise ratios can be measured over a range of 0 to 99.99 dB. Rear outputs are provided to allow for X-Y plotting. Excellent for ATE system with built-in HP-IB.
