Using a passive antenna (VE3DO loop) with a Clifton Labs Z10042 11 dB Norton amplifier connected directly to Red Pitaya at N6TV, strong intermodulation from two nearby FM broadcast stations on 92.3 and 106.5 MHz was clearly visible (106.5 - 92.3 = 14.2 MHz):
Inserting the 14:1 transformer between the pre-amp and the Red Pitaya reduced the intermod significantly, and atmospheric band noise (wideband sensitivity) improved by about 4 dB:
Recently there has been an article published in Nature Physics which describes the use of Red Pitaya in a project of relativistic electron bunches in synchrotron light sources. This project was done at French national synchrotron radiation facility SOLEIL. We are proud to say that Red Pitaya was not not just a part of the experiment but the FPGA was the main component of the control.
Red Pitaya, a pioneer of low cost, open-source, reconfigurable instrumentation, has launched a new, uprated version of its STEMlab™ credit-card-sized platform that is tailored for HF+50MHz SDR (Software-Defined Radio) and RF applications that require DAQ systems with higher precision.
