Dear Azelio, Tom, John and Luciano ( I hope I am not missing anybody), Thank you all of you for your kind advise on this subject. I am sorry I was unable to reply in a timely manner. I had to leave town for a week for new IT business. I think I will start by dismantling the unit display and test the tantalum capacitors as you mentioned. If I can achieve success by doing this it is fine. Otherwise I could consider using it as the GPIB workhorse as I just started to obtain my first ADEV, MDEV and TDEV graphs with TimeLab and a Prologix adapter. May I know the command for turning the display off via the GPIB port? That is something nice for long periods of sampling.
A whole new world has just opened to me. Know I am starting to get intimate with my frequency standards by knowing them in deep. If all goes well I should start updating my wish list for a Wavecrest DTS unit next year. For now I will squeeze every single Tau value from the graphs using the 53132A. Last but not least. If the display fades away I could eventually consider buying a new one as the whole instrument is in pristine condition and would be a shame to see it working without a brilliant display. Thank you for all your feedback. Wishing you all a pleasant evening/morning.
