Greetings to all, thank you Magnus and Bob for the information, I hope there is someone who has the image copy of the Eprom so I can try to update my HP 5372A I would be curious to try it with this option! Regarding the use of Stable32 it is possible to please have some more information on how to configure the program as long as it acquires data from the 5372A, I have both a Prologix interface and a N.I. what do you recommend to use? Regards 73 de IZØTYD - Claudio [email protected]
