CR-S2 frequency sweeper is a simplified CR-S1-type multifunctional tester in our store. It is small in size and has the size of a cigarette case. It uses two 10440 lithium batteries (3.7V * 2), it retains the core function of the multifunctional tester-frequency sweep signal generator. With the oscilloscope, the intermediate frequency can be accurately locked at 465, 455 or 10.7, and a beautiful intermediate frequency curve can be debugged, which can bring great satisfaction to us electronic fanatics both visually and audiologically. This instrument is divided into 455/465kHz and 10.7MHz versions. The power limit of the battery eliminates the crosstalk caused by the use of alternating current, and the waveform is very clean.
