Improved phase noise enhances signal generators

Aeroflex has enhanced its S-Series signal generators (SGA and SGD) with improved phase noise and better RF level accuracy. At a carrier frequency of 1GHz, phase noise is now improved by 6dB at frequency offsets from 100kHz to 1MHz, giving a figure of typically -140 dBc/Hz between these offsets. The S-Series does this while maintaining the frequency settling time of 100µs.

The SGD is further enhanced by the addition of wideband analogue modulation and ARB (Arbitrary Waveform Generator) sequence mode. Analogue 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 satisfy the requirement for customers working with analog, as well as the latest digital standards. ARB sequence mode is a powerful and flexible feature that provides the fastest test sequencing for RFIC design verification and production test. Its ability to rapidly hop frequencies and change waveforms enables complex test scenarios to be created for use in radar, jamming, and electronic countermeasure applications,” said David Asquith, product manager for Aeroflex signal sources.
