Model SC2111

8 GHz 60 dB PXI RF Amplifier
National Instruments P/N PXI-5691

SC2111-300x300
PXI RF Amplifiers offer fixed gain and configurable gain in a single-slot, 3U PXI module. They also can programmatically bypass the gain by switching to a direct path. This functionality enhances testing and monitoring performance of compatible PXI RF Vector Signal Analyzers by letting you shift the dynamic range to easily monitor very weak and very strong signals.

 

Typical Applications

  • Optimizes Dynamic Range and Sensitivity of RF Vector Signal Analyzers
  • Design Verification Test
  • Semiconductor Production Test

The PXI-5691 is a two-channel, programmable amplifier offering one fixed gain path and one programmable gain path in a single-slot 3U PXI module. The PXI-5691 has gain and noise figure characteristics that optimize the dynamic range and sensitivity of compatible PXI RF Vector Signal Analyzers. The PXI-5691 can also programmatically bypass its gain by switching to a direct path. This functionality enhances the testing and monitoring performance of compatible PXI RF Vector Signal Analyzers by enabling you to shift the dynamic range to easily monitor both very weak and very strong signals.
