HIGHLIGHTS
N8211A performance analog upconverter synthetic instrument module is an analog microwave source that generates a stimulus signal by upconverting a baseband signal with superior AM, FM, phase and pulse modulation capabilities (external or internal modulation). The N8211A is based upon the PSG analog signal generator's high output power, low phase noise and excellent level accuracy.
The synthetic instrument family offers the highest-performing RF/MW LAN-based modular instrumentation and the smallest footprint for automated test systems (ATSs); providing the maximum flexibility, and minimizing the cost of an ATS over its lifetime. See a photo of the small modular size mounted in a rack.
Features
- LXI compliant
- Similar performance to the E8257D PSG
- Coherent LO input/output ports allowing use of a common LO signal with multiple upconverters to provide coherent upconversion capability
- CW, digital step, or analog ramp sweeps
- Optional step attenuator; narrow pulse capability; enhanced phase noise performance
