The signal generator architecture is similar to a transmitter. It upconverts the generated signal (from VCO to DAC) to the desired RF frequency and output power.

The Network Analyzer is the combination of both Signal Generator and Signal Analyzer. There is a RF source acting as a transmitted signal and four identical receivers acting as received signals, which are a1, a2, b1 and b2. S11, S12, S21, S22 can get from a1, a2, b1 and b2 after computer calculation.
