Several important indicators for the selection of microwave RF frequency meters

　　A frequency meter is an electronic instrument commonly used by electronic hardware engineers. It is an independent device used to measure signal period, frequency characteristics, and other functions, and is a specialized measuring instrument for measuring the frequency of the measured signal. Compared to oscilloscopes, frequency meters have higher accuracy in testing the frequency of signals, and their measurement accuracy does not vary slightly with gear changes, making them a professional frequency measurement tool. A high-precision frequency counter is a domestically produced frequency meter that can measure parameters such as average, maximum, minimum, and peak to peak values. Today we will learn about several important indicators

　　The number of significant digits is the range of measurement, starting from the leftmost point of the measurement result and the first non zero digit

　　Measurement time: Measurement time refers to the time it takes for the frequency meter to obtain a valid measurement result each time. For the frequency measurement method, the measurement time is the gate time

　　Measurement error: The smaller the measurement error, the better the performance of the frequency meter. Of course, the higher the technical requirements and the more expensive the price will be

　　The large touch screen is easy to operate and use. For example, during measurement, the average frequency value, maximum value, and minimum value are displayed on the interface at the same time. We can compare the numerical differences of the three to determine whether errors can be clearly seen and whether there are any abnormalities in the measured signal
