So there is no need for additional I/O card. A mouse was connected to the mouse port and a printer was connected to the parallel port. There is one serial port. A external modem connected the serial port and the external modem connected with two unterminated telephone cables on the line and phone jack. The Line Jack of EUT was connected to a simulator of ADSL. 1.5 Test Procedure All measurements contained in this report were performed according to the techniques described in Measurement procedure ANSI C63.4-1992 "Measurement of unIntentional Radiators."

The final configuration of the test system and the mode of operation used during these tests was chosen as that which produced the highest emission levels. However, only those conditions which the EUT was considered likely to encounter in normal use were investigated. The system's radiated and conducted emissions were investigated while the computer alternately transferred data to the EUT as well as to the monitor and printer. Using a test program which sent a continuous stream of “H” characters to monitor and transferred data to and from the EUT was proven to wor…
