Stanford SG390 Vector Signal Generators

SG390 Series - Up to 6GHz vector signal generators

Stanford Research Systems

Introducing the new SG390 Series Vector Signal Generators — high performance, affordable RF sources.

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

The instruments use an ovenised SC-cut oscillator as the standard timebase, providing a 100 fold improvement in the stability (and a 100 fold reduction in the in-close phase noise) compared to instruments which use a TCXO timebase.

Conventional analog modulation is supported: Amplitude, frequency and phase can be modulated by internally generated sines, ramps, triangles, squares, Gaussian noise with adjustable bandwidth, by user waveforms, or, by external inputs. An embedded music clip can be broadcast to AM and FM radio receivers.

The instruments also provide versatile vector modulation: I/Q modulators and a powerful dual baseband generator support ASK, FSK and PSK (including BPSK, QPSK, OQPSK, π/4DQPSK, 8PSK, and 16PSK) as well as QAM (4–256), MSK, CPM(1–4 bits), VSB and direct I/Q modulation by external sources with over 100 MHz bandwidth. TDMA is supported and there are four rear panel symbol clock and event timer outputs.
