Two 50-MHz waveform generators offer powerful operating features to meet the requirements of bench test and automatic test equipment applications in consumer and industrial electronics, biomedical applications, and automotive manufacturing. The Model 80 combines a function generator, a linear and logarithmic sweep generator, and a phase-lock generator with DC output. The Model 81 provides a function generator, a pulse generator with leading and trailing edge timing control, and a phase-lock generator, in addition to a built-in counter/timer that automatically detects external reference frequencies in the PLL operating mode. Price: Model 80—$4495; Model 81—$5590. Fluke, www.fluke.com.
