Auction Builder by HP 8903B Audio Analyzer provides unparalleled versatility and performance for audio measurements from 20 Hz to 100 kHz. The HP8903B combines the functionality of a low-distortion audio source, high-performance distortion analyzer, frequency counter, ac voltmeter, dc voltmeter and SINAD meter into one compact package. With microprocessor control of source and analyzer, the HP8903B can perform stimulus-response measurements, such as signal-to-noise ratio and swept distortion, automatically with no additional equipment. For ease of use, most measurements on the HP8903B are made with only one or two keystrokes. Both instruments automatically tune and autorange for maximum accuracy and resolution. For quick identification of input signals, the analyzer counts and displays the input frequency in all ac measurement modes. Low Frequency Applications The HP8903B has many features which make difficult audio measurements easy. These include flexible data display formats, a selectable balanced or unbalanced input, plug-in filters, and automatic notch filter tuning. With the ratio key, you can establish a reference in % or dB and directly make frequency response and 3 dB bandwidth measurements without computation. A fully balanced analyzer input allows testing of bridged power amplifiers found in many radios and car stereos as well as professional balanced audio equipment. With two internal plug-in filter slots and six optional filters to choose from, we simplify your audio measurements by providing the filter networks required by international standards. The HP8903B uses true-RMS detection (for all signals with crest factor 3) for accurate measurement of complex waveforms and noise. Average and quasi-peak detectors are also available. Accurate distortion measurements typically can be made down to less than -90 dB (0.003%) from 20 Hz to 20 kHz. For receiver testing, the instrument has a tunable SINAD notch filter. On the HP8903B, the filter is automatically tuned to the source frequency.
