Keysight Waveform Generators Selection Guide


Keysight Waveform Generators from TranscatThe Agilent function generator has long been the standard in electronics testing. Under its new name, Keysight now offers several general-purpose waveform generators. The most important specifications to use when selecting a function generator are: how many channels are required, what is the maximum frequency, what is the maximum sampling rate, what are the inputs and outputs, and whether the unit has the ability to program arbitrary waveform, or if it has to be purchased as an option. Use the handy guide below to help you select the right Keysight waveform generator. Keysight function generators can also be controlled and monitored with Keysight’s Benchvue software.
