Wide Range As Anritsu's press statement (on the left) notes, its new generator can cover a frequency range from 250-kHz all the way up to 6-GHz. The (optional) 6-GHz upper frequency range is just what's needed for WLAN (wireless local area networking) tests in the 5-GHz band. That upper range should come in handy as well when testing next-generation communications systems that are pushing into the higher frequency allocations, too. Not stated is that you can set the MG3700A's frequency to within 0.01-Hz. Pretty good resolution, eh?
