If you ask a hundred engineers who created the commercial function generator, at least 99 will tell you it was Wavetek — which was not quite the case. It's close, but there are several people who ...

The first-generation integrator-hysteresis-switch FGs were replaced by a second-generation design scheme using current sources. The integrator-based FG loop can be improved by driving the integrating ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

A former coworker friend sent me a Tektronix 3-slot mainframe and several plug-in modules (Fig. 1). The TM500-series mainframes are 1970s vintage, but like a lot of old test equipment, can still work ...

Bioengineers who specialize in creating tools for synthetic biology have unveiled the latest version of their 'biofunction generator and bioscilloscope,' an optogenetic platform that uses light to ...
