It allows us to conclude that the proposed meter can be used to determine the
frequency of the swip-generator with stopped frequency fluctuations. In the scheme,
the swip-generator V2 has frequency 50 kHz, the harmonics of the range of reference
generators E2, E3 have initial frequencies 25 kHz and 25.01 kHz, respectively. The
frequency change velocity of these harmonics is 50 kHz / s, and filter at the output of
the mixer X1 has a resonance frequency 50 kHz.
Transient processes (fig. 4.6) in the case of a change frequency of a sweep-
generator by a quadratic law confirm the conclusion that was made in the third chapter.
Nonlinearity of the frequency deployment doesn’t affect the accuracy of the
measurements.
