The Tektronix 7603 is a 100 MHz analog oscilloscope mainframe from the Tektronix 7000 Series. The Tektronix 7603 accepts up to three 7-series plug-in modules for configuring vertical and horizontal measurement functions. The Tektronix 7603 includes a readout system that displays alphanumeric data from plug-in units on the CRT.[1][2][3]
What it is
The Tektronix 7603 is an analog oscilloscope mainframe that belongs to the Tektronix 7000 Series. The 7603 provides a bandwidth of 100 MHz. The mainframe incorporates a CRT display with an 8 x 10 division graticule; each division measures 1.22 centimeters. The 7603 accepts interchangeable 7000-series plug-in modules in three compartments: two vertical compartments and one horizontal compartment.[1][2][3]
How it works
The Tektronix 7603 operates as a modular analog oscilloscope mainframe. The instrument contains three compartments that accept Tektronix 7-series plug-in units. Two compartments on the left are connected to the vertical deflection system. The right compartment is connected to the horizontal deflection system. Electronic switching between the vertical plug-in compartments enables a multi-trace vertical display. The instrument includes a readout system that displays alphanumeric information from the plug-in units on the CRT. The maximum power consumption of the 7603 is 170 watts. The power supply accepts input frequencies from 48 Hz to 440 Hz.[4][3]
Applications
The Tektronix 7603 is designed for general-purpose measurement applications. The 7000 Series platform supports a wide range of plug-in modules, enabling configurations for dual-trace amplification, spectrum analysis, sampling, and logic probing. The mainframe's flexible architecture makes it suitable for use in electronics laboratories, universities, military test stations, and research and development facilities.[2][3]
