Model 220 Biomedical Function Generator

The Model 220 Function Generator is designed especially for the biomedical and low-level instrumentation field, offering features not found on any other generator in its price range.  It provides constant amplitude sine, square, and triangle waveforms, with a frequency range of 0.01 Hz to 10kHz.  It features a calibrated variable output from zero to ten volts peak-to-peak, utilizing a vernier control and six switch-selected full scale ranges of 100uV, 1mV, 10mV, 100mV, 1.0V and 10V.  Accuracy is +/-2% of full scale on each range and has a constant output impedance of 100ohms.  The output mode switch allows selection of differential (balance) or common (single-ended) outputs.
