NI’s Getting Started documentation identifies this product as the “NI PXI-5691 8 GHz RF Amplifier.” The same document states that the NI 5691 is a two-channel programmable RF amplifier and that it provides fixed gain and programmable gain in a single-slot PXI module. This confirms the PXI-5691 as RF test hardware rather than a DAQ device. https://download.ni.com/support/manuals/376267a.pdf
NI’s support model page describes the PXI-5691 as a 2-channel, programmable amplifier and states that it can programmatically bypass its gain by switching to a direct path. NI also identifies the hardware as a single-slot 3U PXI module. https://www.ni.com/en-za/support/model.pxi-5691.html
