HYBRID MULTIMODE NETWORK ANALYZER

摘要

Network analysis employs a band-limited multi-tone test signal having a tunable center frequency to test a device under test (DUT). A hybrid network analyzer includes a test signal source to provide the band-limited multi-tone test signal, and a local oscillator (LO) source to provide a tunable LO signal configured to track the tunable center frequency of the band-limited multi-tone test signal. The hybrid network analyzer further includes a receiver to convert into an intermediate frequency (IF) signal using the tunable LO signal one or both of the band-limited multi-tone test signal and a response signal from a device under test (DUT) produced in response to the band-limited multi-tone test signal. The test signal source is further configured to provide a tunable single-tone test signal and a broadband multi-tone test signal to test the DUT in various modes.

1. A hybrid network analyzer comprising:
a test signal source configured to provide a band-limited multi-tone test signal having a tunable center frequency; a local oscillator (LO) source configured to provide a tunable LO signal, the tunable LO signal being tunable to track the tunable center frequency of the band-limited multi-tone test signal; and a receiver configured to convert into an intermediate frequency (IF) signal using the tunable LO signal one or both of the band-limited multi-tone test signal and a response signal from a device under test (DUT) produced in response to the band-limited multi-tone test signal, the IF signal comprising a plurality of IF tones corresponding to tones having different frequencies from one another within the band-limited multi-tone test signal.
