1. This product uses the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. Using a high accuracy VCO source, the heterodyne signal frequency can be measured very accurately. Since the scanning range is very large (35M-4400M), because there is no special detection circuit for the external measurement signal due to cost and other factors, the measurement amplitude may have errors. Therefore, the product increases the magnification and displacement parameters, and the user can adjust the display waveform by himself. The amplitude display is adjusted and calibrated.

2. Internally integrated lithium battery charging circuit, due to logistics safety reasons, this product is shipped without battery. By default, USB is used to supply power. Customers can add lithium batteries by themselves.
