-This system was constructed particularly for VLBI, but was already used during test measurements also for spectroscopy,​ continuum and pulsar observationsThis frequency range is not free of interference. Observers wanting to do continuum or pulsar observations might have to search for a frequency range not obstructed by interference and/or use a narrower bandwidth.+{{ :​electronics:​rx:​techinfo:​bsb_p26mm_holo_20210316.pdf |Block Diagram}} ​of the P26mm
