NI PXI/PCI-5401/5411/5431
Output Enable

You can specify which feature to disconnect and connect different devices to the NI PXI/PCI-5401/5411/5431 during operation. However, even when the output enable relay is OFF, the waveform generation process continues internally on the NI PXI/PCI-5401/5411/5431.

You can change the output enable state at any time during waveform generation. When you change this setting, the bouncing of electromechanical relays in Function Generator/Frequency List mode on the NI PXI/PCI-5401/5411/5431 distorts the output signal for approximately 200 ms. In the Arbitrary Waveform/Arbitrary Sequence Waveform mode on the NI PXI/PCI-5401/5411/5431 the output signal is distorted for approximately 10 ms.
