Frequently asked questions

What is the primary difference between the R&S SMA and SMB analog generator lines?
The SMA series (such as the SMA100A and SMA100B) is optimized for ultra-low phase noise and peak level performance, whereas the SMB series (such as the SMB100A) is engineered as a highly versatile, compact RF and microwave generator that balances fast setting times with robust signal quality.
Which R&S generators support multiple independent RF paths in one instrument?
Both the SMW200A and the SMU200A vector signal generators support configuration with up to two independent RF paths, enabling complex multi-antenna, dual-carrier, or fading simulation tests.
How is the SGT100A optimized for production lines?
The SGT100A features a headless (no display) 1 HU, 1/2 19" rack form factor. It is controlled remotely via Gigabit LAN or PCIe interfaces to ensure high-speed setting times and small footprints in automated test equipment racks.
