The wide bandwidth IQ modulator exhibits excellent dynamic range enabling the most demanding amplifier and receiver selectivity measurements to be performed. The use of Aeroflex’s Fast Low Noise Synthesis (FLNS) technology, added to the experience gained through decades of developing leading-edge signal source products, ensures that signal purity and integrity have not been sacrificed in the quest for speed; the SGD excels in all respects.

An embedded version of IQCreator®; Aeroflex's powerful waveform creation tool enables the user to design waveform files from generic or system specific templates as well as convert user designed waveforms into compatible formats and include signal impairments and time markers to aid sychronization.

With a comprehensive range of features and options, the SGD meets the needs for a general-purpose signal generator while offering the high performance required of demanding, critical receiver measurements or rapid manufacturing.

An SGD “Aerolocked” to an SVA signal analyzer is a powerful system test tool in the size of one conventional instrument and the AeroLink between instruments allows them to co-operate in making measurements.
