Automated Double Frequency Test System (ADFTS)
|
 |
General potentialities:
-
automated detection, identification, and measurement of parameters for the desired path and all spurious (image, intermediate-frequency, etc.) paths, through which interference can influence the device under test;
-
automated detection, identification, and measurement of radio receiver susceptibility to nonlinear effects: blocking (desensitization), cross-modulation, intermodulation of all types and orders, etc;
-
electromagnetic compatibility analysis and prediction in the complex electromagnetic environment with the use of double-frequency testing results.
|
The main idea of this technology:
-
radiolocation of the radio receiver through its antenna input, using the sum of two frequency-sweeping signals (Vf1>>Vf2) and original synchronous tomography visualization of the receiver output on the PC display;
-
discrete simulation of signal-noise-interference mixture transformation in the receiver (discrete EMC-analysis and prediction)
