SG390 Series Vector Signal Generators
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 GEfz) and
extraordinary frequency resolution (1 uFfz at any frequency).
Both analog modulation and vector baseband generators are
included as standard features.
The instruments use an ovenized 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.
A New Frequency Synthesis Technique
The SG390 Series Signal Generators are based on a new
frequency synthesis technique called Rational Approximation
Frequency Synthesis (RAFS). RAFS uses small integer
divisors in a conventional phase-locked loop (PLL) to
synthesize a frequency that would be close to the desired
frequency (typically within ±100 ppm) using the nominal PLL
reference frequency. The PLL reference frequency, which is
sourced by a voltage controlled crystal oscillator that is phase
locked to a dithered direct digital synthesizer, is adjusted so
that the PLL generates the exact frequency. Doing so provides
a high phase comparison frequency (typically 25 MHz)
