The invention provides a gain control index testing method of a radio frequency receiver. The gain control index testing method of the radio frequency receiver includes the following steps: sending an instruction from a main control computer to a radio frequency signal tester to inquire radio frequency signal power, recording a power peak value as Pk, recording a power peak value obtained after power is increased step by step as Pk+1, judging whether an absolute error between the PK+1 and the Pk is larger than delta Pmax or not, if the absolute error is smaller than the delta Pmax and a gain attenuation value of a presently tested radio frequency receiving device is smaller than a maximum attenuation value of the tested radio frequency receiving device, repeating the inquiring process, and if the absolute error between the PK+1 and the Pk is larger than the delta Pmax or the gain attenuation value of the presently tested radio frequency receiving device is larger than or equal to the maximum attenuation value of the tested radio frequency receiving device, ending the test. The gain control index testing method of the radio frequency receiver is controlled by a computer, compared with a manual testing method, the gain control index testing method of the radio frequency receiver improves information utilization rate and is automatic in testing process.

The invention relates to the field of natural medicines, in particular to a method for quickly discovering low-content active ingredients in natural products. The method divides the whole components of natural medicine into high-content components and low-content components through relative quantification, and uses the high-resolution chromatographic peak fraction preparation method to directly establish a high-content fraction library and obtain corresponding mass spectrum information. After knocking out these high-content components, the low-content components were enriched, and the low-content fraction library was obtained after solvent concentration and secondary separation, and the mass spectrum information of the low-content components was obtained at the same time. On this basis, activity screening was carried out on high and low content fractions respectively. This method has the advantages of rapidity, precision, high degree of automation, simple operation, low cost, and strong applicability, and is suitable for the discovery of low-level active ingredients in natural products.
