Tektronix
530
The Tektronix 530 series oscilloscopes were introduced by Tektronix in the late 1950s (1957–58). The Tektronix 530 series were the first oscilloscopes to feature interchangeable plug-in units for horizontal sweep or vertical input. The Tektronix 530 series also introduced the delayed trigger function.[1]

What it is
How it works
The 530 series introduced the delayed trigger capability, which allowed triggering between a sweep rather than at the beginning, providing more stable triggering and better waveform reproduction.[1]
The plug-in design of the 530 series permitted different vertical and horizontal plug-ins to be installed, making the oscilloscope an adaptable test instrument.[1]
Applications
Later Tektronix added plug-ins to allow the oscilloscope to operate as a spectrum analyzer, waveform sampler, cable tester, and transistor curve tracer, expanding the utility of the 530 and 540 series instruments.[1]
