Embodiment Construction
[0029] figure 1 A high speed sampling unit 1 is shown comprising a sampling arrangement 2 comprising a track and hold unit 7 operating in a time interleaved mode 1 , track and hold unit 7 2 To track and hold unit 7 N . In some cases, the high-speed sampling unit 1 can be integrated in a single chip or ASIC (Application Specific Integrated Circuit). However, it is also possible that the sampling device 2 can be integrated on its own chip, while the analog / digital converter 3 1 , A / D converter 3 2 to A / D converter 3 N on a separate chip. It should be noted that the A / D converter 3 1 , A / D converter 3 2 to A / D converter 3 N Included for better understanding only in figure 1 However, they are not essential components of the present invention. The sampling device 2 also comprises a first input port 4 and a second input port 5 . An electrical input signal, ie an RF (Radio Frequency) signal, is input to the first input port 4 . RF signals are high frequency signals with ...
