Aeroflex S-series 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 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 a 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. The SGD enhancements satisfy the requirement for customers working with analog, as well as the latest digital standards. The ARB sequence mode is a powerful and flexible feature that provides the fastest test sequencing for RFIC design verification and production test.
