Two vintage electronic test instruments: a Heathkit Model IB-28 impedance bridge in a sloped benchtop cabinet and a Hewlett-Packard Model 330B rack-panel distortion analyzer. The IB-28 is a four-arm bridge designed to measure resistance, capacitance, inductance, dissipation factor, and storage factor, with a built-in 1 kHz generator and 100-0-100 microampere meter. Published ranges are 0.1 ohm to 10 megohms, 100 pF to 100 µF, and 0.1 mH to 100 H. Its assembly manual is dated 1968. The Hewlett-Packard 330B model was introduced in 1945 and measures distortion across 20 Hz to 20 kHz. Its front panel includes AF and RF input selection, frequency range and tuning controls, distortion, noise and meter functions, balance, meter range, and oscilloscope output terminals. Both instruments retain analog meters, rotary controls, and binding-post connections.
