The Phase Matrix Model 1313B microwave downconverter translates microwave signals to RF frequencies with minimal distortion and provides the user with basic microwave front-end conditioning building blocks to extend VXIbus signal analysis into the microwave range. In conjunction with an appropriate external local-oscillator module and commercially available digitizer, this single-slot downconverter solution can provide the functions of several stand-alone instruments.

Description Specification
Frequency Range 100 kHz to 26.5 GHz
Noise Floor < -135 dBm
