Signal Generator Tunes 9 kHz to 1.2 GHz

AR Worldwide has introduced the model SG1200, a compact signal generator with 1-Hz frequency resolution from 9 kHz to 1.2 GHz. Output-power levels can be adjusted from -140 to +13 dBm with 0.1-dB resolution. The phase noise is better than -124 dBc/Hz offset 20 kHz from a 470-MHz carrier and typically -121 dBc/Hz offset 20 kHz from a 1-GHz carrier. Spurious levels are better than -70 dBc to 1 GHz and better than -64 dBc through 1.2 GHz. Harmonics are typically -25 dBc for power levels through +13 dBm. The signal generator, which occupies a 2U rack-mount space, operates locally or through RS-232C or GPIB remote control. It includes a variety of modulation formats, including AM, FM, and FSK.
