There are plenty of designs out there for sawtooth and triangle function generators, many of them using the humble 555 IC. Few are readily voltage controlled, making them difficult to work with using ...

A lifetime of amassing random pieces of test equipment has left me with a gap in my armoury, namely that I don’t possess a low frequency function generator. This could easily be addressed, but for two ...

The AG4151 from Saelig Company, Inc. is an economical, dual-channel multi-function generator which combines arbitrary waveform and function generation using Direct Digital Synthesizer (DDS) technology ...

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 ...
