The standard specifications allow these sources to be used off the shelf without any extra options in a wide range of different applications and offer a high degree of performance at a very attractive price. For example, the price of the 1.5 GHz model is only 1880 Euros net and includes superior technical data are like ±0.5 dB amplitude accuracy, +20 dBm maximum output power as well as great signal purity and phase noise less than -105 dBc/Hz at 20 kHz.

Further features are 0.5 ppm frequency stability and standard AM/FM/ΦM modulation with a frequency resolution of 0.01 Hz. There is an internal or external modulation capability on all modulation types. The devices have standard remote control interfaces USB and LAN and support SCPI control.

There are three options available to enhance the stability and the functionality of the signal generators. The highly stable oven oscillator (Option OCXO-A08) enhances the temperature stability of the internal clock from 0.5 ppm to 5 ppb. In addition the pulse train generator option (PUG-DSG800) and the pulse modulation option (PUM-DSG800) are available. The pulse options of the DSG800 allow to either output a pre- or self-defined pulse sequence or allow the output of pulse modulated signals.

The DSG800 is a perfect extension of Rigol’s existing RF generator family and completes the company’s overall portfolio. For more challenging applications, the models DSG3030 (3 GHz) and DSG3060 (6 GHz) offer higher specifications (such as maximum output power of 25 dBm and phase noise under 110 dBc/Hz, amongst others). Further options include power meter control (PMC-DSG3000) and – most important – the possibility to do digital IQ modulation (IQ-DSG3000). This IQ option enables the generation and output of digitally modulated signals. The signals can be generated internally and either output as modulated RF signal or as base band I and Q signals. In addition it is possible to modulate externally input I and Q base band signals with frequencies up to 6 GHz.
