Used TEKTRONIX 7904 #9234834 for sale

TEKTRONIX 7904 is an analog-to-digital oscilloscope designed to measure and plot electrical signals. It was first introduced in 1976 and was a very popular oscilloscope that was used in laboratories all over the world. It is capable of displaying very accurate signals that have frequency up to 40MHz, resolutions up to 5kHz, and input sensitivities up to 1mV/div. It has a 7-inch CRT display and four independent channels. Each channel has its own input connectors, trimmer controls, and switches to select the input voltage and coupling. 7904 has two input amplifiers—isolation amplifiers and differential amplifiers. The isolation amplifier amplifies the base signal before it is processed by TEKTRONIX 7904's hardware. The differential amplifier then takes the amplified signal and any other signals and separates them from each other to improve the overall accuracy of measurement. 7904 also has an AC-coupled function that functions like a low-pass filter. It can be used to filter out unwanted noise from the signal, allowing only the desired signals to be visible on the screen. TEKTRONIX 7904 also has an auto-trigger function which automatically activates the scope as soon as it detect certain patterns on the signal. 7904 is a reliable oscilloscope that is used by laboratories and engineers all over the world. It is a very useful tool in analyzing the behavior of circuits and digital logic. Its high accuracy and range of features make it ideal for a variety of tasks involving signals and electrical engineering. In addition to providing highly accurate measurements, TEKTRONIX 7904 also features an easy-to-use interface that allows for convenient operation and monitoring of signals. Its affordability makes it a great tool for students and hobbyists alike who need to measure and monitor electrical signals.
