Abstract
A spectrum analyzer for measuring an electrical response of a device under test (DUT) includes a test port for receiving radio frequency (RF) signals from the DUT in response to a test signal transmitted to the DUT, a local oscillator (LO) for generating a LO signal, a sampler connected with the LO to receive the LO signal and a receiver connected with the sampler. The sampler includes a non-linear transmission line that generates a sampler signal having a frequency that is a multiple of a frequency of the LO signal, and an input for receiving a RF signal from the test port. When a RF signal from an RF input source is received the sampler outputs an intermediate frequency (IF) signal. The receiver receives the IF signal output of the sampler.
