Model SC2112

8 GHz 60 dB PXI RF Attenuator
National Instruments P/N PXI-5695

SC2112-300x300
The PXI RF Attenuator provides two channels of programmable attenuation with one fixed attenuation path and one programmable attenuation path. The combined paths can provide up to 60 dB of total attenuation when cascaded. Using an external attenuator, you can generate RF signals in the most accurate range of the signal generator and attenuate the signal to the desired output power.

 

Typical Applications

  • Attenuates RF input signals to improve the power accuracy of your RF signal generator in lower power ranges
  • Design Verification Test
  • Semiconductor Production Test

The PXI-5695 is a two-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 can generate RF signals in the most accurate range of the signal generator and attenuate the signal to the desired output power.
