FINALLY, SOME MODELS BECAME AVAILABLE AT A LOW OR MODERATE COST BY SACRIFICING PERFORMANCE IN THE AREAS JUST LISTED AS PROBLEMS. HOMEBREWED MODELS REQUIRING SELECTED PARTS OFTEN APPEARED AS AN EXERCISE IN ART RATHER THAN ELECTRONIC DESIGN. IN THIS REVIEW, I LOOK AT FIVE DIFFERENT SIGNAL GENERATORS. THERE ARE MAJOR DIFFERENCES IN THE DESIGN AND RESULTING CAPABILITIES BETWEEN TODAYS MODELS AND THOSE OF SEVERAL YEARS AGO, BEFORE THE AVAILABILITY OF DIGITAL INTEGRATED CIRCUITS AND MICROPROCESSORS. DIGITAL SYNTHESIS RATHER THAN BEING CONCERNED WITH INDUCTANCE TO CAPACITANCE RATIO AND THE TEMPERATURE COEFFICIENT OF CAPACITORS, MOST GENERATOR MANUFACTURERS TODAY LOOK AT A REPETITIVE WAVEFORM AS A SET OF POINTS. EACH POINT HAS AN AMPLITUDE, AND THE MORE POINTS READ AND CONVERT TO AN ANALOG VOLTAGE OR DIGITAL WAVEFORM PER SECOND, THE SMOOTHER THE OUTPUT WAVEFORM. SELECTING A WAVEFORM TO GENERATE = END OF 25 WPM TEXT = QST DE W1AW <
