Optics

100 nA/div (1 nA resolution) to 2 A/div^[2]

What it is

The Tektronix 370 A can source up to 2000 volts or 10 amps, with a maximum power of 220 watts. The instrument offers a measurement resolution of 1 nanoamp in current and 2 millivolts in voltage. The 370 A is fully programmable and features a 3.5-inch MS-DOS-compatible disk drive for saving and recalling setups. The instrument provides Kelvin sense measurements for accurate device characterization.^[2]

How it works

The Tektronix 370 A includes features such as waveform comparison, envelope display, waveform averaging, and a dot cursor for precise measurement. The instrument supports Kelvin sense measurements to eliminate lead resistance errors. The 370 A is fully programmable and can store and recall setups from a 3.5-inch MS-DOS disk.^[2]^[3]

Applications

The instrument is designed for high resolution DC parametric characterization of semiconductor devices, supporting both manual and automated testing.^[2]
