Rohde & Schwarz SME03 Signal Generator 5 kHz - 2.2 GHz
Description
Rohde & Schwarz SME03 Signal Generator 5 kHz – 2.2 GHz supplies the complex signals required for the development and testing of digital mobile radio receivers. It is capable of generating all signals used in the main digital radio networks in line with relevant standards regarding the type of modulation, data format; TDMA structure and frequency hop patterns. The large variety of options available allows the SME to be tailored to the specific needs of the user.
Features
- All common digital modulation modes provided in one unit
- Great ease of operation thanks to a novel menu concept
- No external modulation and data sources required
- User-programmable data sequences and TDMA structure
- RF, LF and level sweep
- Ultra-low RF leakage for measurements on highly sensitive pagers
