PXIe-5451 DC Output Configuration Clarification

[Veera.Tessolve]

I’m using an NI PXIe-5451 Arbitrary Waveform Generator in my setup. According to the specifications, the module supports three load types: 50 Ω, 1 kΩ, and Open. For my test requirement, I need to force 5 V DC to an op-amp input (high-impedance load).
However, I’m unable to select the “Open” load type in LabVIEW (NI-FGEN) and instrument studio.

Questions:

1. How can I configure the PXIe-5451 output for an open-load (high-impedance) condition in LabVIEW?

2. If I keep the output open-load (no termination), can the PXIe-5451 source 5 V DC?

3. If not, what is the maximum DC output voltage the PXIe-5451 can provide in open-load condition?

4. Here load impedance means Output impedance of PXle-5451?

Thanks,
