These errors are generated when a problem occurs that is specific to one of the test set's instruments. These errors are part of the test set's core. Note that these measurements may not be present in every test application and therefore, these errors may not be present in every test application. There is no plan at present to support test application specific instruments.
An instrument in this context refers to the measurement-like functionality such as the audio generator and not to the test set as a whole.
When one of these errors is generated, the `+600 errors' bit in the questionable error status register is set.
