3 General Requirements
3.1 If there are no special instructions, the range of environmental or reference point temperature deviation from the specified value during testing should comply with the detailed specifications of the device.
. During the testing period, external interference should be avoided from affecting the testing accuracy. The testing error caused by the testing equipment should comply with the detailed specifications of the device During the 3.3 test period, the internal resistance of the power supply applied to the tested device should be basically zero at the signal frequency; The deviation of the power supply voltage should be within 1% of the specified value. The accuracy of other electrical parameters applied to the tested device should comply with the detailed specifications of the device During the linear working area testing of the tested device, the gradual reduction of AC small signal amplitude should not cause changes in parameter values. 3.5 When the tested device is connected or disconnected from the testing system, the service limit conditions of the device should not be exceeded If required, the power supply should be connected in the order specified in the detailed device specifications During the testing period, the tested device should be connected to the auxiliary circuit and compensation network specified in the detailed specifications. During the testing period, the tested device should avoid self excitationFunction of testing report:
