A microwave sign generator, the SMB100B from R&S affords 4 frequency choices overlaying 8 kHz to 12.75 GHz, 20 GHz, 31.8 GHz, and 40 GHz. This midrange analog sign generator offers single sideband (SSB) part noise of <-106 dBc (measured) at 20 GHz with an offset of 20 kHz and <-100 dBc (measured) at 40 GHz with a 20-kHz offset. In accordance with R&S, the SMB100B additionally displays low wideband noise for all service frequencies.
Output energy choices of 25 dBm at 20 GHz and 19.5 dBm at 40 GHz are activated by keycode and will be put in at any time. Along with the instrument’s customary OCXO reference oscillator, a high-performance variant is on the market throughout all frequency ranges. It enhances close-in part noise and frequency stability, whereas lowering sensitivity to temperature variations.
The SMB100B has a typical 10-MHz reference frequency. An optionally available 1-MHz to 100-MHz variable exterior reference frequency enter permits the unit to be built-in into present take a look at environments. The acquired reference frequency can be despatched to a separate reference output. A 1-GHz reference frequency enter and output possibility improves part stability between a number of SMB100B devices.
The SMB100B microwave sign generator (as much as 40 GHz) is on the market now and joins the prevailing RF fashions (as much as 6 GHz).
