In part 1 of this series, “Circuits test key op amp parameters,” we addressed some of the basic op amp (operational amplifier) tests such as VOS(offset voltage), CMRR (common-mode rejection ratio), PSSR (power-supply rejection ratio), and Aol (amplifier open-loop gain). In this arti...
The items of test equipment that are commonly found are multimeters, analogue and digital (DMM - digital multimeter), oscilloscopes, and under some circumstances more specialised test equipment including spectrum analyzers may be used.Test Instruments...

Use the ground terminal of the test instrument correctly. Use the electronic instrument with the ground end connected to the chassis for testing. The ground end together should be connected with the ground end of the amplifier. Otherwise, the interference introduced by the instrument chassis will ...
