HP / Agilent 8648B 9 kHz - 2 GHz Synthesized RF Signal Generator
The HP / Agilent 8648B 9k-2GHz Synthesized RF Signal Generator is ideal for manufacturing high-volume products such as cordless telephones, pagers and two-way radios. Designed for semi-automated receiver test, and a variety of general purpose applications, the Agilent 8648B starts with the basic capabilities of the Agilent 8647A, enhances residual FM, level accuracy and phase noise performance, offers optional pulse modulation and high power, and extends the frequency to 2 GHz. While economical, the Agilent 8648B is built to stringent quality standards, promoting reliability and measurement repeatability.
HP/Agilent 8648B Synthesized Signal Generator Features:
- Economical 2.0 GHz synthesized signal generator
- Superior level accuracy
- Wide frequency and output power coverage
- Optional pulse modulation and high power
- Remote and memory interfaces for semi-automated testing
- Simple, dependable operation
