The basic concept The specific coordination between the load impedance and the impedance in the source during signal transmission. A relationship between the output impedance of a piece of equipment and the load impedance connected to it, so as to avoid obvious influence on the working state of the equipment itself when connected to the load.

Q4: sweep mode selection: sweep or FFT? A: the sweep mode of modern Spectrum Analyzer usually has sweep mode and FFT mode. FFT generally has a speed advantage over sweep when set to a narrower RBW, but sweep mode is faster when set to a wider RBW. When sweep width less than the FFT analysis bandwidth, FFT model can measure the transient signal;

1. The entrusting party shall provide the list of instruments to be calibrated (including instrument name, model specification, range and specific quantity), which can be sent to our business specialist by mail, fax, QQ, etc. If quotation/inquiry is required,

Q1: The smaller the resolution bandwidth (RBW), the better? A: The smaller the RBW, the better the sensitivity of the spectrum analyzer suplied from Wholesale Spectrum Analyzer. However, the scanning speed will be slower.

Also known as a Signal Generator, it is used to generate electrical test signals with specific parameters required by the circuit under test.

How to set up the high sensitivity of the Spectrum Analyzers to facilitate the observation of small signals? A: first, set the corresponding center frequency sweep width (span) and reference level according to the size of the small signal under test
