A system for the testing of ADCs at the frequency range of 1 MHz, which was designed and prototyped at the Dept. of Measurement, CTU FEE last year, was extended up to 20 MHz. Low-cost as well as high-quality filters for frequencies about 4.4, 9.5 and 19.5 MHz were manufactured. Experimental results showed that the system is directly applicable for the testing of ADCs with the ENOB up to 11-13 in case of low-cost filters and up to 20 in case of high-quality filters.
