The new RF Signal Generator Series DSG800 enhances Rigol’s presence in the RF Measurement domain. The new source is available with bandwidths of 1.5GHz or 3GHz and addresses customers in Wireless Communication, Radar Test, Audio/Video Broadcasting, Education and Consumer Electronics.

The standard specifications allow these new sources to be used off the shelf without any extra options in a wide range of different applications.

The price of the 1.5GHz model is 1880 Euros net and includes +/- 0.5 dB amplitude accuracy, +20 dBm maximum output power as well as excellent signal purity and phase noise of < -105 dBc/Hz@20 kHz.

Other features are 0.5ppm frequency stability and standard AM/FM/ΦM modulation with a frequency resolution of 0.01Hz. 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 completes the company’s RF generatorl portfolio. For more challenging applications, the previous models DSG3030 (3GHz) and DSG3060 (6GHz) offer higher specifications (e.g. maximum Output Power 25 dBm / Phase Noise <110 dBc/Hz) and offer additional options as well.

These include the 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 6GHz.
