Replacing the FAN.... Old FAN: Papst 8500N, 110 Volts 34 dB, 61 m3/hour New FAN, Noctua, NF-R8 12 Volts 17 dB, 53 m3/hour The unit stays very cool, no problems with temperture. The uP was getting hot, also in the old situation, so placed a cooling strip on th uP. Fore the GPIB i use the Prologic, is also quite expensive, but works very good. But was already in use for other equipment. can make your own software on the easy way, as post somewhere above. i also use Free pascal for that. |

I have no experience with it, but I've heard this Agilent 82357 clone works reasonably well: http://www.measuretechnic.com/?product=m82357-usbgpib-interface-alternative-to-agilent-82357b It can be had for < $100, though still a bit expensive for what it is, it's not too bad a price for such a niche item, assuming it works as advertised. |

I also just bought one of these too! I'll post pictures in a day or two. Also, w/o the high stability time base I believe but with the 1.3 GHz option. Considering a necessary timebase upgrade, for a cheap option (<<$100), the morion mv89a double oven OCXO's for $25-35 on ebay seemed like the best option for possibly (depending it's condition) 10-11/sec stability and even 10-8/year discussed here: http://www.ke5fx.com/Morion_MV89A_IEEE_IFCS_2002.pdf 10E-8 would be quite good enough for me. The HP 10811 option, from the specs I saw did not seem to be nearly as good, and looked likely $100+. |

You rather have a look at the power supply, the Morion neets lot of juice on the 12V line where the 10811 is only supplying oscillator and oven controller because of its dedicated Heater connector. |

Well, here's what I got off ebay, a serial prefix 2323A model with option 010, 030 and 040. Typical horror story, the seller shipped with the fan flopping around by the power leads smashing things up a bit. I collected 5 loose parts and identified a couple broken leads. But, I got the 10811-60111 timebase unexpectedly. I need to replace the broken off caps and transistors before I'll power on. It was shown working in the listing. Allan |
