Introducing the new SG390 Series Vector Signal Generators — high performance, affordable RF sources. Three new RF Signal Generators, with carrier frequencies from DC to 2.025 GHz, 4.050 GHz and 6.075 GHz, support both analog and vector modulation. The instruments utilize a new RF synthesis technique which provides spur free outputs with low phase noise (–116 dBc/Hz at 1 GHz) and extraordinary frequency resolution (1 μHz at any frequency). Both analog modulation and vector baseband generators are included as standard features.
