TEST CIRCUIT
test circuit includes some electrical switches that should be in the suitable positions for the measurement of each
parameter. For the best measurement of each parameter, the drawings of ”Test Circuit 1 to 10” are additionally
prepared to show the switching positions and other changes of connection. Note that “Test Circuit 1 to 10” are not
the complete circuit to measure.
This test circuit allows the measurement of all parameters described in “ELECTRICAL CHARACTERISTICS”. This
Note :
1. “CD” means a ceramic discriminator of 455kHz ;
