Hi I have a 53132A which seems to be working OK. Passes the power on self test, also passes the ALL TEST self tests (in Utility menu: power + recall key) and passes calibration procedures. However, when I choose specifically the FR END test in the utility menu, for which you have to connect the 10MHz out to ch1 and ch2 via a BNC-T, it always fails. Can anyone with a working unit try this test and see what happens? My unit came with original option 010. History: the power supply and the 38V VFD supply were dead which I fixed and now all voltages are well within specs and solid but I am not sure about their noise. Could that be the problem? Perhaps replacing the PSU caps would help? |

Actually there are some VFDs on ebay.com right now from China for $95 each This is not the ITRON model but it should work well. https://www.ebay.com/itm/112732008985 |

I have seen those on ebay but I was hoping to find it cheaper. The seller offered $85 but the shipping to Canada is also $30 So $115 for display is a bit too much... |

I just bought an HP 53132A on Ebay that was listed as parts only with a blank display. I gambled and got it and it looked pretty good. It had the 3 Ghz card and the HS oscillator (010 option) but as shown on Ebay, the display was completely dark. I took the case off and visually inspected the inside and the only problem at first glance was the white bumper on the main board was completely melted with just some goo remaining. Looking more closely I noticed one cap in the power supply had a bulging top so I replaced that 1000 uF/16V cap and the counter works perfectly. It took a while to find which REV I had so I could access the cal procedure but once I got that info and went through the cal menu, everything seems to be working as it should, even the display looks fairly bright. I had to relube the fan because it wouldn't always start on its own but after the oil worked its way onto the entire shaft it worked o.k. as well. If the fan was stopping that might have shortened the life of the faulty cap. I'll replace all of the power supply caps, just in case. |
