Title:
MIXED-DOMAIN OSCILLOSCOPE, AND MEASUREMENT METHOD AND SYSTEM WITH MIXED-DOMAIN OSCILLOSCOPE
Document Type and Number:
Japanese Patent JP2014145757
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To generate a chirp signal, supply it to a DUT, and measure a return signal from the DUT using an MDO.SOLUTION: An MDO 105 includes: a signal generator 160 configured to generate a test signal having a span ranging from a user-configurable start frequency to a user configurable stop frequency; an output channel 115 configured to transmit the test signal; an RF input channel 120 configured to receive a return signal based on the test signal; an acquisition section configured to acquire and digitize the return signal as an acquisition record; and a ramp busy signal generator configured to substantially time-align the acquisition record with the test signal. The test signal may be a chirp signal that is a linearly swept sine wave that spans between the user-configurable start frequency and the user-configurable stop frequency.
