RIGOL steps up RF measurement performance

RIGOL Technologies is extending its presence in the field of RF measurement technology with the RF signal generator series DSG3000B (IQ).

The new signal source is available for 9 kHz to 6.5 GHz or up to 13.6 GHz and is aiming at customers from the sectors wireless communication, radar test, audio/video broadcasting, training, consumer electronics and EMC test solutions.

As with all HF generators from RIGOL, there is an IQ version also for this device.

The high standard specifications enable the new signal generator series to be used in many different applications without additional options and offer exceptional performance, the proven RIOGL quality and a very attractive price. This instrument is very easy to operate and offers a high level of signal stability.

The amplitude accuracy of <0.5 dB (typ.) as well as the very high signal purity and the low phase noise of less than -116dBc/Hz@20kHz underline the high performance of the devices.

The amplitude is specified from -120 dBm to +20 dBm and can be set for a frequency range from 200 MHz to 3.6 GHz up to +27 dBm or from 100 kHz to 6.5 GHz to -130 dBm. The +27 dBm in particular are ideal for testing components such as mixers.

The instrument offers <2ppm (standard) frequency stability of the internal reference clock, optionally 5ppb (highly stable crystal) and a standard AM/FM/ΦM generation (up to 3.6 GHz) with a frequency resolution of 0.01 Hz.

All modulations can be controlled by an internal or external source. USB and LAN are available as standard remote control interfaces and SCPI commands are supported.

The functions range of the signal generators can be expanded with three options. On one hand the highly stable reference clock (option OCXO-B08), which improves the temperature stability of the internal reference frequency from <2ppm to 5ppb.

Furthermore, pulse train generation (DSG3000B-PUG) and pulse modulation (DSG3000B-PUM) are available (up to 3.6 GHz) as options.

The pulse options of the DSG3000B (IQ) enable the output of predefined or self-created pulse trains and the output of pulse-modulated signals. A combination of different modulation sequences can also take place here. With the frequency and amplitude sweep, a large number of applications can be implemented.

The four new DSG3065B(IQ) and DSG3136B(IQ) devices complement the previous DSG8000 (A) and replace the somewhat older DSG3000 (IQ) family.

The comprehensive basic equipment, the good specifications, the high flexibility through the optional extensions and the excellent price-performance ratio and the excellent price-performance ratio, which is typical for Rigol, make the new RF signal sources a very interesting alternative to other sources available on the market.
