The SGD also gets added wideband analogue modulation and 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 company notes that phase noise improvements will benefit customers using an S-Series signal generator for classic receiver tests, especially 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 analogue, as well as the latest digital standards. ARB sequence mode 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.
