Saelig Co. (Fairport, NY) announced Rigol DSG800 RF signal generators with output frequencies from 9 kHz to 3.0 GHz. They provide an RF signal source with a maximum output of +20 dBm and frequency resolution of 0.01 Hz at any frequency. Featuring SSB noise of -115 dBc/Hz, they feature a stable internal clock for creating RF test signals. The instruments provide conventional sweep functions (step, list, logarithmic, and linear) as well as analog modulation functions including amplitude modulation, frequency modulation, phase modulation, and pulse modulation. They also offer an optional pulse train generation capability for translating serial data onto an RF link without additional hardware. The pulse train can be used as the modulating signal of pulse modulation, and can also be output as an independent pulse generator.

The instruments support external pulse modulation, but the internal pulse generator can produce baseband signals with adjustable cycle times and pulse widths. They produce pulse modulated signals with a rise/fall time of less than 10 ns, and an on/off ratio greater than 70dB. Frequency stability can reach 5 ppb by choosing the high stable reference clock option. They have full remote control capability for integration into Automated Test Environments (ATE).
