513

An oscilloscope is an electronic test and measurement instrument that displays electrical signals as visible traces against time. Oscilloscopes are used to inspect waveform shape, amplitude, timing relationships, noise, and transient behavior during development, maintenance, and laboratory measurement.

The Tektronix Type 513D is a portable, self-contained instrument designed to display variations of a voltage pulse or wave with respect to time and to provide means of measuring duration and magnitude. The Tektronix Type 513D uses a 5XP cathode-ray tube with 12 kV accelerating voltage. The Tektronix 513 has a hard-tube sweep circuit that can operate in triggered or recurrent modes. The Tektronix 513 provides sweep magnification of approximately 5 times. The Tektronix 513 has a vertical amplifier with a distributed output stage. The Tektronix 513D variant provides a 0.25 microsecond signal delay that permits observation of the wavefront that triggers the sweep.^[2][3]

Oscilloscopes are bench instruments used around semiconductor, electronics, and precision equipment workflows rather than in the direct material processing path. Oscilloscopes are typically used alongside power supplies, signal sources, probes, and fixtures during equipment checkout, subsystem troubleshooting, and verification of analog or pulse behavior.

The Tektronix Type 513D was primarily intended for study of short duration pulses. The Tektronix Type 513D was particularly useful where a high writing rate was required or where single high-speed sweeps were to be photographed. The Tektronix 513 can synchronize on signals as high as 10 MHz.^[4][3]
