The power source must be isolated from other equipment connected to the antenna or output. Room temperature...............................77 degrees F (25 degrees C). AM BAND Speaker impedance:...................................................8 ohms Output readings are taken across a non-reactive load. Output reference level is 50 mW total power. The generator output terminates in an IRE loop with the loop pointing toward the rear of the receiver.

(An over voltage of 10% is acceptable.) FM BAND Speaker impedance:...................................................8 ohms Use resistive load. Reference output level:...............................................50 mW Signal generator impedance:.........................................75 ohms Disconnect telescopic antenna cable. The signal voltage in this specification or test data is the voltage appearing across the tuner input terminals.

All units should be able to approximate these - some will exceed and some may drop slightly below these specs. Limit specs represent the absolute worst condition which still might be considered acceptable: in no case should a unit fail to meet limit specs. (br/all-07/11/95)
