Aeroflex has enhanced its S-Series signal generators with improved phase noise and better RF level accuracy. At a carrier frequency of 1 GHz, phase noise is now improved by 6 dB at frequency offsets from 100 kHz to 1 MHz, giving a figure of typically -140 dBc/Hz between these offsets. The S-Series does this while maintaining its industry-leading frequency settling time of 100 µs.
The SGD is further enhanced by the addition of wideband analog modulation and ARB (Arbitrary Waveform Generator) sequence mode. Analog modulation provides internal AM, FM, and phase modulation. ARB sequence mode allows the user to set up a sequence of waveforms generated in the ARB to provide a rapid test sequence.
The phase noise improvements will benefit customers using an S-Series signal generator for classic receiver tests. This is particularly true when the signal generator is used as a local oscillator substitute or as an interfering signal where improved test margins in receiver selectivity and signal-to-noise measurements will allow the testing of higher quality receivers. The SGD enhancements meet the requirement for customers working with analog, as well as digital standards.
There is an ARB sequence mode which provides fast test sequencing for RFIC design verification and production test. It has the ability to rapidly hop frequencies and change waveforms enables complex test scenarios to be created for use in radar, jamming and electronic counter measure applications.
The SGD is the Digital Signal Generator & the SGA is the Analog Signal Generator in the S Series.
