8 GHz, 70 dB PXI RF Attenuator—The PXI‑5695 is a 2‑channel programmable attenuator with one fixed attenuation path and one programmable attenuation path. The combined paths can provide up to 70 dB of total attenuation at 2.5 GHz when cascaded. With the PXI‑5695, you can improve the power accuracy of your RF signal generator in lower power ranges. With an external attenuator, you generate RF signals in the most accurate range of the signal generator and attenuate the signal to the desired output power.
