We have new and used oscilloscopes for sale from Tektronix: a leading manufacturer of oscilloscopes. Science, engineering, telecommunications, medical, and automotive industries use oscilloscopes to observe constantly varying signal voltages. This piece of test equipment records the change of an electrical signal over a period of time. Tekronix oscilloscopes continuously graph the voltage of a piece of equipment against a calibrated scale, creating a waveform you can analyze for rise time, time interval, amplitude, frequency, and more. Maintain your electronic equipment with general-purpose or special-purpose oscilloscopes. We buy and sell Tektronix analog, digital, mixed domain, mixed signal, and other oscilloscopes for a variety of needs.
