Used TEKTRONIX 2714 #115191 for sale

TEKTRONIX 2714 is an analog voltage/current oscilloscope that was introduced in 1967. It is a highly precise instrument used to measure and analyze the electrical signals of advanced electronics. This particular model has two synchronized vertical channels and enhanced X-Y operation, allowing for complex signal relationships to be more easily displayed and analyzed. The horizontal linearity is twelve divisions, offering a high level of accuracy when measuring frequency and amplitude. The vertical input sensitivities are quarter of a volt per division, and the vertical input impedance, typically fifty ohms, is variable from three to five thousand, with the variable resistor located on the back of the CRT assembly. For eased viewing, the EB and A1 grids can also be electrically switched. The horizontal input sensitivity is 0.2 microsecond/division for thirty two division sweeps, and a minimum sweep speed at 0.2 second/division. The A2 and EB control knobs control the sweep rate and speed. The timebase calibration frequency is adjustable with the CAL (calibration) knob. The amplifier characteristics can be adjusted with the amp and scope var controls. The deflection factor of the CRT is approximately 4.3mA per cm, ensuring very precise measurement of impulse widths of frequency components. There is also a triangular frequencilly-modulated CRT sweep output allowing for greater viewing accuracy at low horizontal sweep speeds as it incorporates a triangular voltage that is readback. The trace position, size and intensitiy are determined by means of the screwdriver-adjust potentiometers located on the face of the scope. The scope also features an X-Y operation that is provided by a second vertical amplifier. The sweep of this amplifier is a constant-current regulated supply, the reduction of which causes the X-Y current to be reduced, meaning that both the X and Y amplitudes can be amplified in excess of a large input range. For added features, 2714 also offers an external triggering capability from a separate-input. This external trigger enables users to easily synchronize to external signals, as well as provide a wipe-off pattern. The scope has power requirements of +5V, +10V, -5V and -12V, drawing approximately 130W. Its chassis is a steel-reinforced aluminum which makes it a sturdy and reliable tool for use in many laboratory environments long-term. Its reliability and robust design make it highly sought after in the market even today.
