National Instruments NI PXIe-5601 10MHz- 6.6GHz RF Downconverter - tested

Description

One National Instruments (now just NI) PXIe-5601 RF downconverter in good physical and functional condition.  This downconverter is a lot more than just a mixer, it's a complete functional block of mixers, filters, and amplifiers which comprises the downconversion stage of the PXIe-5663 vector signal analyzer and others.  When fed an LO and configuration data, the unit will amplify as needed, downconvert to a 187.5MHz (or 53MHz in one frequency band) IF with required image rejection filtering.  The unit does not have a direct RFSA soft front panel interface, but can be controlled through LabView or direct interface (an example VI automates a companion PXI/PXIe-5652 frequency and level control), and can be combined with a PXI LO source and digitizer to operate through the RFSA soft front panel.  This unit tests good and some sample modulations downconverted from an RF signal are pictured.
The PXIe-5601 module features:
10MHz to 6.6GHz RF input frequency
>50MHz instantaneous bandwidth above 330MHz (some examples pictured)
<-154dBm/Hz typical noise floor across all bands (better at lower frequencies)
104+dB nominal spurious free dynamic range
PXIe Mainframe interface (Not compatible with older PXI only mainframes)
Fully software configurable and programmable through LabView and others
Full specification available from NI's website
You will get the PXIe-5601 module itself and none of the pictured other equipment used in testing and demonstration.  At the time of listing, I am also selling a PXI-5652 and PXIe-5652 modules which can provide the LO source to this downconverter in other listings.
Ships via USPS Priority to the US or internationally.  I have other electronic parts, test equipment, and test equipment parts available in my store, and shipping is automatically discounted on multiple items.  Feel free to ask any questions.
