Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
The megger test on a generator is usually done to check the insulation factor of a generator. The high voltage is usually used to test the insulation system of a the generator in question. It is recommended to do this test after every six months.
When using a resistive load bank to test a generator, it does not matter if you load the generator to its kW or kVA rating, because those two numbers are the same when considering a resistive load. Power factor, which is the difference between true and apparent power, only comes into play when there is a reactive (inductive or capacitative) load.
scope probes
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
A specific pattern can identify a fault. For example, if the first input of an AND gate is struck at zero, then a test vector of 10 or 11 can identify that fault. These two vectors are called as a test set. Generation of such a pattern is done by a pattern generator.
synchronous generator
load test on dc shunt generator is a test to plot the internal and external characteristics of the generator.
The most used pattern generator on the web is the ADC Generator. Their patterns are used by the majority of computer makers and they have a good reputation.
in swin burn test we find out the copar loses & iron loses of the dc generator

A function generator is a piece of electronic test equipment. Its main use is to generate electrical waveforms.
Any voltage source, whether a generator or a battery, will NOT supply an output current unless it is connected to a load. So the only way to test the output current is by connecting it to a load.
we can predetemine the efficiency of a dc machines working as a motor or generator
Run the test signal through a small isolation transformer.
