FEATURES The Model 590 CV Analyzer is a sophisticated instrument designed as a complete solution for individuals requiring capacitance and conductance versus voltage measurements in semiconductor testing. The unit can test devices at either 1OOkHz or 1MHz, depending on installed modules. The Model 590 1OOk tests at 10OkHz, while the Model 590/1M operates at 1MHz. The Model 59O/1OOk/1M can test at both 1OOkHz and 1MHz. Test voltage for both frequencies is 15mv RMS. The Model 590/100k measures capacitance and conductance on four ranges: 2pF/2µS, 2OpF/20µS, 200pF/200µS, and 2nF/2mS (the optional Model 5904 Input Adapter can extend the 1OOkHz measurement range to 2OnF/20mS). Key Model 590 features include: A standard internal +2OV bias source that can generate staircase, pulse train, or DC waveforms. Provision to connect an external bias source of up to +-2OOV DC are also included. Two 450-word internal buffers to store capacitance (C), conductance (G), and bias voltage (V) data taken during testing. Two complete sets of C, G, V~d.ata can be stored; one set can be saved for plotting while another test is being performed. Standard plotter driver software allows the Model 590 to contro1 an intelligent digital plotter over the IEFE-488 bus, simplifying a variety of different plot types,
