<p>PURPOSE: A test method of a one-to-one matching type frequency transceiving card and an apparatus using the same are provided to perform simply the test of a transmitting card and a receiving card as necessary, thereby reducing greatly temporal and spatial load. CONSTITUTION: An audio jack(A-JACK) is connected to transmission card-sided contact points(TP31,TP6). A frequency signal is transmitted or received with a computer. A transformer(T) is connected to reception card-sided contact points(RP31,RP24). In a first power supply end, a first driving positive voltage(+10V) is commonly connected to the transmission card-sided contact points and the reception card-sided contact points.</p> |
