Overview
National Instruments PXI RF signal conditioning modules include low-noise/
high-gain amplifiers and programmable attenuators. You can use these 3U PXI
modules to optimize the dynamic range of PXI RF vector signal generators and
analyzers. The NI PXI-5690 is a 100 kHz to 3 GHz, two-channel programmable
amplifier and attenuator; the NI PXI-5691 is a 50 MHz to 8 GHz, two-channel
programmable amplifier; and the NI PXI-5695 is a 50 MHz to 8 GHz, two-channel
programmable attenuator.

RF Signal Conditioning Applications
You can use PXI programmable amplifiers with both RF signal generators and
RF signal analyzers. When combined with RF vector signal generators, PXI RF
amplifiers enable high-power signal generation. For example, the PXI-5691 offers
up to 28 dB of gain and a 1 dB compression point of +21 dBm. Using this module,
you can extend the upper power range of your vector signal generator.
When used with RF vector signal analyzers, the same programmable
amplifiers can improve the noise floor of the measurement system. For example,
with a typical noise figure of 5 dB at 2.5 GHz, the PXI-5691 programmable
amplifier can be combined with the NI PXI-5663 RF vector signal analyzer to
measure signals down to -163 dBm/Hz.
With PXI programmable attenuators, 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.
Note:
All values are typical results at either 2.5 or 6.6 GHz.

Amplifier/Attenuator
The PXI-5690 is a 100 kHz to 3 GHz, two-channel programmable amplifier and
attenuator with one fixed gain path and one programmable gain/attenuation
path. The combined paths offer up to 37 dB of total signal gain at 2.5 GHz when
signal paths are cascaded.
