Function generators (FGs) are measurement instruments in the category of waveform sources. They grew out of both a need for a versatile source of multiple waveshapes and from some interesting analog ...

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 ...

Sometimes, there are too many choices in this world. My benchtop function generator can output a sine, square, or saw wave anywhere from 0.01 Hz up to 60 MHz? Way too many choices. At least, that’s ...

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 ...

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 ...
