IO-103 5-inch Triggered Sweep Oscilloscope

The Heathkit IO-103 5-inch Triggered Sweep Oscilloscope
is an accurate and dependable instrument which has a wide
range of applications. When properly assembled and calibrated,
the Oscilloscope can be used to observe or measure all types
of electrical and electronic waveforms within its listed
specifications, from relatively simple sine and square waves
to complex pulse and composite signals. The basic uses of this
instrument are similar to those of other oscilloscopes with
comparable sensitivity and frequency response.
