Fig. 1-3 PMM ER8000 Functional BLOCK Diagram
The input stage integrates a switch system able to select the signal source
coming from the N panel connector or from the desired line of the internal
LISN. Then, the path can go toward the blocks designed for conducted or
radiated (\COND) measurements. The RF (Radiated) module is equipped
with its own attenuator and preselection filters bank. The A to D conversion
and processing stages are in common between conducted and radiated
modules.
The stages designed for conducted measurements are able to handle
frequencies at least from 9 kHz up to 30.1 MHz and the radiated module
can handle frequencies from 28 up to 3000 MHz.
All the IF filters are numerically calculated by the FPGA-DSP so they are
very stable and don't need frequent recalibration.
