This page describes the rev0SNA 50-2500 MHz Scalar Network Analyzer (SNA).

==Summary==

The rev0SNA is based around three primary modules: the [[SA_LO1|1st Local Oscillator]], [[SNA_PDet|Power Detector]], and [[SNA_DCpl|Directional Coupler/Reflectometer]]. The 1st Local Oscillator is used as a signal generator, which passes through the directional coupler/reflectometer to port 1. The DUT is placed between port 1 and port 2. Port 2 connects to the power detector, which can be switched between measuring the Thru (S21) and Reflect (S11) powers, coming either from port 2 or the output from the directional coupler/reflectometer.
