The Rohde SMHU58 is a 100 kHz to 4320 MHz Synthesized Signal Generator. The Signal Generator R&S SMHU58 is identical with R&S SMHU apart from an additional extremely broadband I/Q modulator making for high versatility. Any digital modulations can be generated with the aid of Software IQSIM-K for computing user-programmable waveforms of Generator ADS. This is a particularly invaluable feature in view of new modulation standards. The coder options provide modulation signals in line with the relevant standards.
