Description
The Rohde SMHU is a 100 kHz to 4320 MHz, Signal Generator. R&S SMGU and R&S SMHU are ideal for applications which the majority of signal generators cannot handle. In addition to out-of-channel measurements, they are for instance able to determine the spurious rejection of radiotelephone equipment up to 4 GHz as laid down by CEPT.

Frequency Characteristics
- The frequency can be set with a resolution of 0.1 Hz over the entire range, and this is sufficient even for measurements on extremely narrowband DUTs. Both instruments supply frequencies down to 1 kHz.
- The frequency setting time is below 10 ms. In the fast mode up to 200 user-defined frequencies can be handled by means of a trigger signal or by memory sweep in less than 1 ms per setting. Spectral purity
- R&S SMGU / R&S SMHU fulfill requirements for selectivity measurements on top-class receivers. Signals of extremely high spectral purity afford critical adjacent-channel, in-channel and out-of-channel measurements with a wide tolerance margin.
- Phase noise remains low right up to the carrier. R&S SMGU and R&S SMHU are therefore ideal for LO applications or as a low-noise reference in noise measurement systems. Frequency modulation
- The FM modulation frequency range extends from DC to 1 MHz. In FM DC mode a high carrier-frequency accuracy is attained. The frequency offset occurring with FM DC selected is extremely small. Amplitude modulation
- The whole of the modulation frequency range can be used down to carrier frequencies of less than 100 kHz. The minimal phase shift at 30 Hz (AM DC) and a flat frequency response make for the precision amplitude modulation that is required for testing VOR/ILS navigation receivers. Pulse modulation
- Rise/fall times of 20 ns (typ. <10 ns for frequencies >200 MHz) and an on/off ratio of 80 dB open up a wide range of possibilities for testing telemetry, microwave link, radar and satellite communications systems. Digital and analog sweep
- In addition to the digital, step-by-step sweep with presettable start and stop frequency, span, step width and step time, an analog frequency and level sweep is also provided. Phase offset
- The phase of the RF output signal can be varied in steps of 1 using keyboard entry or the spinwheel. This makes it easier to adjust for phase quadrature during noise measurements and to investigate phase-critical components.
