N8212A Performance Vector Upconverter LXI Module, 250 kHz to 20 GHz


N8212A performance vector upconverter synthetic instrument module is a vector microwave source with greater than 1 GHz I/Q modulation bandwidth to generate a stimulus signal by upconverting a baseband signal. It features superior AM, FM, phase and pulse modulation capabilities (external or internal modulation). The N8212A is based upon the PSG vector signal generator.

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.


  • LXI compliant
  • Similar performance to the E8267D 20 GHz vector signal generator
  • 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 sweeps
  • Standard high output power and step attenuator
  • Optional narrow pulse capability; enhanced phase noise performance
