Specifies whether to use input signals for measurement or internal test generator.

Parameter syntax: SignalSource

Possible values: Inputs, Test

Default value (RST condition): Inputs


Built-in test signal generator is used for performing internal device calibrations but can also be used for testing purposes. This setting must be used only for testing or demonstrational purposes when there is no possibility to connect external source of signal to instrument’s inputs.

Inputs- Normal operation

Test - Using internal test signal generator instead of inputs on front (back) panel. Output of the internal generator are connected to inputs A, B, D, E and can be measured. Please, note: test generator is using independent coarse time base and is not expected to provide accurate frequency. It is not the same generator which drives rear Pulse Output of the device.
